Is 6% too high to trade stocks on margin?
"6% isn't ""too high"" in terms of market rates at the moment, however it's a very subjective question whether it's too high for you. The real question to determine is if paying 6%, can you make more than 6% return (to cover the costs plus your profit)? As for a rule of thumb, there's none I know of, however your best bet is to take the time to model it in Excel (not difficult).  It's different for each portfolio or investment. Something with a high standard deviation of returns is already high risk, adding margin to it only makes it worse.  So, long story short is that, ""it depends""." Okay so we are assuming that you can sustain 6% or more return on your investments.   Personally I would compare that rate to what lines of credit are going for and do what ever is least expensive.   Either way your risk is the same.  Your net worth is the same.  Your assets will be the same. Your liabilities will be the same. Its just a matter of who you owe it to and what the rate is. Don't be afraid of having a second mortgage.  If the stocks go down either way you have to sell what's left and pay your debt. Or what I should maybe say is don't be more afraid of a line of credit more than margin in your investment account. That seems a little high in my experience.  I've used a home equity line of credit instead, as the rates are much lower (~3.5%). Yes, 6% is a waste of money, because some other brokers such as IB offer margin rates below 2%.   Also, to borrow money for even less than any broker's margin interest rate, one can do an EFP transaction.   This involves simultaneously shorting a stock and buying the SSF for the same stock.   When the futures contract expires, you take delivery of the underlying stock to automatically close out your short position.  Until then, you've effectively borrowed cash for the cost of borrowing the stock, which is typically less than 0.5% interest for widely traded ones.  You also pay for the slight difference in price between the stock and the future, which is typically equivalent to another 0.5% interest or less.  The total often comes to less than 1% interest. The only risk with this transaction is that the stock could become hard to borrow at some point, so then you would have to pay higher interest on it temporarily or maybe even have to close out your short early.  But it is extremely rare for large, high-volume stocks to become hard-to-borrow.  The borrowing cost of SPY has spiked above 5% on only a handful of days in the last decade.
You're trying to mitigate the risk of having your investments wiped out by fraud committed by your broker by using margin loans to buy stock secured by other, non-cash assets in your account. The solution that you are proposing does not make any sense at all. You mitigate a very low probability/high impact risk by doing something that comes with a high probability/medium impact risk.  In addition to interest costs, holding stocks on margin subjects you to the very real risk of being forced to sell assets at inopportune times to meet margin calls. Given the volatility that the markets are experiencing in 2011, there is a high risk that some irrational decision in Greece could wipe you out. If I were worried about this, I would: If you have enough money that SIPC protection limits are an issue, you desperately need a financial adviser. Do not implement any strategy involving margin loans until you talk to a qualified adviser. "I think the question, as worded, has some incorrect assumptions built into it, but let me try to hit the key answers that I think might help: Your broker can't really do anything here.   Your broker doesn't own the calls you sold, and can't elect to exercise someone else's calls. Your broker can take action to liquidate positions when you are in margin calls, but the scenario you describe wouldn't generate them:  If you are long stock, and short calls, the calls are covered, and have no margin requirement.  The stock is the only collateral you need, and you can have the position on in a cash (non-margin) account.   So, assuming you haven't bought other things on margin that have gone south and are generating calls, your broker has no right to do anything to you. If you're wondering about the ""other guy"", meaning the person who is long the calls that you are short, they are the one who can impact you, by exercising their right to buy the stock from you.  In that scenario, you make $21, your maximum possible return (since you bought the stock at $100, collected $1 premium, and sold it for $120.  But they usually won't do that before expiration, and they pretty definitely won't here.  The reason they usually won't is that most options trade above their intrinsic value (the amount that they're in the money).    In your example, the options aren't in the money at all.   The stock is trading at 120, and the option gives the owner the right to buy at 120.* Put another way, exercising the option lets the owner buy the stock for the exact same price anyone with no options can in the market.  So, if the call has any value whatsoever, exercising it is irrational; the owner would be better off selling the call and buying the stock in the market." My interpretation of that sentence is that you can't do the buying/selling of shares outright (sans margin) because of the massive quantity of shares he's talking about.  So you have to use margin to buy the stocks. However, because in order to make significant money with this sort of strategy you probably need to be working dozens of stocks at the same time, you need to be familiar with portfolio margin.  Since your broker does not calculate margin calls based on individual stocks, but rather on the value of your whole portfolio, you should have experience handling margin not just on individual stock movements but also on overall portfolio movements. For example, if 10% (by value) of the stocks you're targeting tend to have a correlation of -0.8 with the price of oil you should probably target another 10% (by value) in stocks that tend to have a correlation of +0.8 with the price of oil.  And so on and so forth.  That way your portfolio can weather big (or even small) changes in market conditions that would cause a margin call on a novice investor's portfolio. With your numbers, look at it this way - You borrowed $50. When the stock is $100, you are at 50% margin.  What's most important, is that there's margin interest charged, so the amount owed will increase regardless of the stock price. When calculating your return or loss, the interest has to be accounted for or your numbers will be wrong. For a small investor, margin rates can run high, and often, will offset much of your potential gain. What good is a $100 gain if you paid $125 in margin interest? "Yes. There are several downsides to this strategy: You aren't taking into account commissions. If you pay $5 each time you buy or sell a stock, you may greatly reduce or even eliminate any possible gains you would make from trading such small amounts. This next point sounds obvious, but remember that you pay a commission on every trade regardless of profit, so every trade you make that you make at a loss also costs you commissions. Even if you make trades that are profitable more often than not, if you make quite a few trades with small amounts like this, your commissions may eat away all of your profits. Commissions represent a fixed cost, so their effect on your gains decreases proportionally with the amount of money you place at risk in each trade. Since you're in the US, you're required to follow the SEC rules on pattern day trading. From that link, ""FINRA rules define a “pattern day trader” as any customer who executes four or more “day trades” within five business days, provided that the number of day trades represents more than six percent of the customer’s total trades in the margin account for that same five business day period."" If you trip this rule, you'll be required to maintain $25,000 in a margin brokerage account. If you can't maintain the balance, your account will be locked. Don't forget about capital gains taxes. Since you're holding these securities for less than a year, your gains will be taxed at your ordinary income tax rates. You can deduct your capital losses too (assuming you don't repurchase the same security within 30 days, because in that case, the wash sale rule prevents you from deducting the loss), but it's important to think about gains and losses in real terms, not nominal terms. The story is different if you make these trades in a tax-sheltered account like an IRA, but the other problems still apply. You're implicitly assuming that the stock's prices are skewed in the positive direction. Remember that you have limit orders placed at the upper and lower bounds of the range, so if the stock price decreases before it increases, your limit order at the lower bound will be triggered and you'll trade at a loss. If you're hoping to make a profit through buying low and selling high, you want a stock that hits its upper bound before hitting the lower bound the majority of the time. Unless you have data analysis (not just your intuition or a pattern you've talked yourself into from looking at a chart) to back this up, you're essentially gambling that more often than not, the stock price will increase before it decreases. It's dangerous to use any strategy that you haven't backtested extensively. Find several months or years of historical data, either intra-day or daily data, depending on the time frame you're using to trade, and simulate your strategy exactly. This helps you determine the potential profitability of your strategy, and it also forces you to decide on a plan for precisely when you want to invest. Do you invest as soon as the stock trades in a range (which algorithms can determine far better than intuition)? It also helps you figure out how to manage your risk and how much loss you're willing to accept. For risk management, using limit orders is a start, but see my point above about positively skewed prices. Limit orders aren't enough. In general, if an active investment strategy seems like a ""no-brainer"" or too good to be true, it's probably not viable. In general, as a retail investor, it's foolish to assume that no one else has thought of your simple active strategy to make easy money. I can promise you that someone has thought of it. Trading firms have quantitative researchers that are paid to think of and implement trading strategies all the time.  If it's viable at any scale, they'll probably already have utilized it and arbitraged away the potential for small traders to make significant gains. Trust me, you're not the first person who thought of using limit orders to make ""easy money"" off volatile stocks. The fact that you're asking here and doing research before implementing this strategy, however, means that you're on the right track. It's always wise to research a strategy extensively before deploying it in the wild. To answer the question in your title, since it could be interpreted a little differently than the body of the question: No, there's nothing wrong with investing in volatile stocks, indexes, etc. I certainly do, and I'm sure many others on this site do as well. It's not the investing that gets you into trouble and costs you a lot of money; it's the rapid buying and selling and attempting to time the market that proves costly, which is what you're doing when you implicitly bet that the distribution of the stock's prices is positively skewed. To address the commission fee problem, assuming a fee of $8 per trade ... and a minimum of $100 profit per sale Commissions aren't your only problem, and counting on $100 profit per sale is a significant assumption. Look at point #4 above. Through your use of limit orders, you're making the implicit assumption that, more often than not, the price will trigger your upper limit order before your lower limit order. Here's a simple example; let's assume you have limit orders placed at +2 and -2 of your purchase price, and that triggering the limit order at +2 earns you $100 profit, while triggering the limit order at -2 incurs a loss of $100. Assume your commission is $5 on each trade.  If your upper limit order is triggered, you earn a profit of 100 - 10 = 90, then set up the same set of limit orders again. If your lower limit order is triggered this time, you incur a loss of 100 + 10 = 110, so your net gain is 90 - 110 = -20. This is a perfect example of why, when taking into account transaction costs, even strategies that at first glance seem profitable mathematically can actually fail.  If you set up the same situation again and incur a loss again (100 + 10 = 110), you're now down -20 - 110 = -130. To make a profit, you need to make two profitable trades, without incurring further losses.  This is why point #4 is so important. Whenever you trade, it's critical to completely understand the risk you're taking and the bet you're actually making, not just the bet you think you're making. Also, according to my ""algorithm"" a sale only takes place once the stock rises by 1 or 2 points; otherwise the stock is held until it does. Does this mean you've removed the lower limit order? If yes, then you expose yourself to downside risk. What if the stock has traded within a range, then suddenly starts declining because of bad earnings reports or systemic risks (to name a few)? If you haven't removed the lower limit order, then point #4 still stands.  However, I never specified that the trades have to be done within the same day.  Let the investor open up 5 brokerage accounts at 5 different firms (for safeguarding against being labeled a ""Pattern Day Trader""). Each account may only hold 1 security at any time, for the span of 1 business week. How do you control how long the security is held? You're using limit orders, which will be triggered when the stock price hits a certain level, regardless of when that happens. Maybe that will happen within a week, or maybe it will happen within the same day. Once again, the bet you're actually making is different from the bet you think you're making. Can you provide some algorithms or methods that do work for generating some extra cash on the side, aside from purchasing S&P 500 type index funds and waiting? When I purchase index funds, it's not to generate extra liquid cash on the side. I don't invest nearly enough to be able to purchase an index fund and earn substantial dividends. I don't want to get into any specific strategies because I'm not in the business of making investment recommendations, and I don't want to start. Furthermore, I don't think explicit investment recommendations are welcome here (unless it's describing why something is a bad idea), and I agree with that policy. I will make a couple of points, however. Understand your goals. Are you investing for retirement or a shorter horizon, e.g. some side income? You seem to know this already, but I include it for future readers.  If a strategy seems too good to be true, it probably is. Educate yourself before designing a strategy. Research fundamental analysis, different types of orders (e.g., so you fully understand that you don't have control over when limit orders are executed), different sectors of the market if that's where your interests lie, etc. Personally, I find some sectors fascinating, so researching them thoroughly allows me to make informed investment decisions as well as learn about something that interests me. Understand your limits. How much money are you willing to risk and possibly lose? Do you have a risk management strategy in place to prevent unexpected losses? What are the costs of the risk management itself? Backtest, backtest, backtest. Ideally your backtesting and simulating should be identical to actual market conditions and incorporate all transaction costs and a wide range of historical data. Get other opinions. Evaluate those opinions with the same critical eye as I and others have evaluated your proposed strategy." Most brokers have a margin maintenance requirement of 30%.  In your example, it would depend on how much money you're borrowing from your broker on margin. Consider this: You have $250, and short AAPL at $500 on margin. This would be a common scenario (federal law requires investors to have at least 50% of their margin equity when opening a transaction). If your broker had a requirement of 30%, they would require that for your $500 position, you have at least $500 * .3 = $150 equity. Since you are currently above that number at $250, you will not be hit with a margin call. Say the price of AAPL doubles, and now your position is worth $1000. $1000 * .3 = $300, which is $50 above your initial equity. Your broker will now consider you eligible for a margin call. Most will not execute the call right away, you will often have some time to either sell/cover stock or add funds to your account. But not all brokers will warn you if you are breaking margin requirements, and sometimes margin calls can take you by surprise if you are not paying attention. Also, many will charge interest on extra margin borrowed. "The T+3 ""rule"" relates only to accounting and not to trading.  It does not prevent you from day trading.  It simply means that the postings in you cash account will not appear until three business days after you have executed a trade.  When you execute a trade and the order has been filled, you have all of the information you need to know the cash amounts that will hit your account three business days later. In a cash account, cash postings that arise from trading are treated as unsettled (for three days), but this does not mean that these funds are available for further trading.  If you have $25,000 in your account on day 1, this does not mean that you will be able to trade more than $25,000 because your cash account has not yet been debited.  Most cash accounts will include an item detailing ""Cash available for trading"".  This will net out any unsettled business transacted. For example, if you have a cash account balance of $25,000 on day one, and on the same day you purchase $10,000 worth of shares, then pending settlement in your cash account you will only have $15,000 ""Cash available for trading"". Similarly, if you have a cash balance of $25,000 on day one, and on the same day you ""day trade"", purchasing $15,000 and selling $10,000 worth of shares, then you will have the net of $20,000 ""Cash available for trading"" ($20,000 = $25,000 - $15,000 + $10,000). If by ""prop account"" you mean an account where you give discretion to a broker to trade on your behalf, then I think the issues of accounting will be the least of your worries.  You will need to be worried about not being fleeced out of your hard earned savings by someone far more interested in lining their own pockets than making money for you." If this is the initial transaction, the rules of a short margin account say that if you shorted 1000 share of ABC at $5/share your credit balance would be $5000 from the short plus you would have to put up yourself $5000 cash or $10,000 of marginal securities. So this is not really leveraging using margin. You have to put in just as much as the short generates. Is that what this relates to? Once the initial purchase has been made the minimum maintenance for a stock trading under $5 per share is 100% of the short market value in the margin account or $2.50 per share whichever is greater. For stock trading at $5/share or greater the minimum maintenance requirement is $5/share or 30% of the short market value, whichever is greater. The minimum maintenance requirements can be tighter. I think George's answer explains fairly well why the brokerages don't allow this - it's not an exchange rule, it's just that the brokerage has to have the shares to lend, and normally those shares come from people's margin, which is impossible on a non-marginable stock. To address the question of what the alternatives are, on popular stocks like SIRI, a deep In-The-Money put is a fairly accurate emulation of an actual short interest.  If you look at the options on SIRI you will see that a $3 (or higher) put has a delta of -$1, which is the same delta as an actual short share. You also don't have to worry about problems like margin calls when buying options.  The only thing you have to worry about is the expiration date, which isn't generally a major issue if you're buying in-the-money options... unless you're very wrong about the direction of the stock, in which case you could lose everything, but that's always a risk with penny stocks no matter how you trade them. At least with a put option, the maximum amount you can lose is whatever you spent on the contract.  With a short sale, a bull rush on the stock could potentially wipe out your entire margin.  That's why, when betting on downward motion in a microcap or penny stock, I actually prefer to use options.  Just be aware that option contracts can generally only move in increments of $0.05, and that your brokerage will probably impose a bid-ask spread of up to $0.10, so the share price has to move down at least 10 cents (or 10% on a roughly $1 stock like SIRI) for you to just break even; definitely don't attempt to use this as a day-trading tool and go for longer expirations if you can. 200% margin for a short sale is outrageous. You should only need to put up 150% margin, of which 50% is your money, and the 100% is the proceeds.  With $100 of your money, you should be able to buy $100 of GOOG and short $100 of PNQI. Depends on the stock involved, but for the most part brokerages allow you gain entry at 50%, meaning you can short twice the cash on hand you have.   Going forward, you need to maintain 30%, so on a $10,000 short, you'd have to maintain $3000 in your account. Example, an account with $5000 cash - You can short $10,000 securities.  Let say 100 shares of xyz at $100 per share. After trade settles, you won't receive a margin call until your balance falls to $3000, probably right around the time xyz rises to $120 per share.  Riskier stocks will have higher margin maintenance requirements - leveraged vehicles like FAS/FAZ (triple leveraged) require 90% margin (3x30%) if they are allowed to be 'shorted' at all. "I think you should start here https://www.tastytrade.com/tt/ and learn about equity options. Its a lot more accessible for you to get hands on experience. Start with learning about put/call spreads and maybe put on some SPY trades. Options are essentially the same in every market; I would start here.    I think this idea you have of not having to use ""margin"" is coming from people running spread strategies that have limited downside/upside" "In my view, it's better to sell when there's a reason to sell, rather than to cap your gains at 8%. I'm assuming you have no such criteria on the other side - i.e. hold your losses down to 8%. That's because what matters is how much you make overall in your portfolio, not how much you make per trade. Example: if you own three stocks, equal amounts - and two go up 20% but one falls 20%. If you sell your gains at 8%, and hold the loser, you have net LOST money. So when do you actually sell? You might say a ""fall of 10%"" from the last high is good enough to sell. This is called a ""trailing"" stop, which means if a stock goes from 100 to 120, I'll still hold and sell if it retraces to 108. Needless to say if it had gone from 100 to 90, I would still be out. The idea is to ride the trend for as long as you can, because trends are strong. And keep your trailing stops wide enough for it to absorb natural jiggles, because you may get stopped out of a stock that falls 4% but eventually goes up 200%. Or sell under other conditions: if the earnings show a distinct drop, or the sector falls out of favor.  Whenever you decide to sell, also consider what it would take for you to buy the stock back - increased earnings, strong prices, a product release, whatever. Because getting out might seem like a good thing, but it's just as important to not think of it as saying a stock is crappy - it might just be that you had enough of one ride. That doesn't mean you can't come back for another one." "The short answer is that it depends on the industry. In other words, margin alone - even in comparison to peers - will not be a sufficient index to track company success.  I'll mention Apple quickly as a special case that has managed to charge a premium margin for a mass-market product.  Few companies can achieve this. As with all investment analysis, you need to have a very clear understanding of the industry (i.e. what is ""normal"" for debt/equity/gearing/margin/cash-on-hand) as well as of the barriers-to-entry which competitors face. A higher-than-normal margin may swiftly be undermined by competitors (Apple aside).  Any company offering perpetual above-the-odds returns may just be a Ponzi scheme (Bernie Maddof, etc.).  More important than high-margins or high-profits over some short-term track is consistency of approach, an ability to whether adverse cyclical events, and deep investment in continuity (i.e. the entire company doesn't come to a grinding halt when a crucial staff-member retires)." Your basic assumption is incorrect. You don't normally go to a bank to borrow money to invest, but brokerages do it all the time. It is called trading on margin.
