How much money are you actually trading with options?
You would have paid $880.00 plus commission in this case, and made $85 before commissions. How much you would have made on expiration depends on the price that TSLA has on April 1, which hasn't come yet.  If it expires worthless, you typically don't pay a commission but you will have lost the full $880.  If it expires in the money and you want to exercise it, then you would pay a commission (often different than the commission to buy/sell the option itself) and you would have 100 shares of TSLA.  You won't know how much you make or lose in this case until you ultimately sell the shares of TSLA.
Yes When exercising a stock option you will be buying the stock at the strike price so you will be putting up your money, if you lose that money you can declare it as a loss like any other transaction. So if the stock is worth $1 and you have 10 options with a strike at $0.50 you will spend $500 when you exercise your options. If you hold those shares and the company is then worth $0 you lost $500. I have not verified my answer so this is solely from my understanding of accounting and finance. Please verify with your accountant to be sure. "With stocks, you can buy or sell. If you sell first, that's called 'shorting.' As in ""I think linkedin is too high, I'm going to short it."" With options, the terminology is different, the normal process is to buy to open/sell to close, but if you were shorting the option itself, you would first sell to open, i.e you are selling a position to start it, effectively selling it short. Eventually, you may close it out, by buying to close.  Options trading is not for the amateur. If you plan to trade, study first and be very cautious." Thanks. Just to clarify I am looking for a more value-neutral answer in terms of things like Sharpe ratios. I think it's an oversimplification to say that on average you lose money because of put options - even if they expire uselessly 90% of the time, they still have some expected payoff that kicks in 10% of the time, and if the price is less than the expected payoff you will earn money in the long term by investing in put options (I am sure you know this as a PhD student I just wanted to get it out there.)I guess more formally my question would be are there studies on whether options prices correspond well to the diversification benefits they offer from an MPT point of view. Just romped a competition my school had, won $100. I'm not participating in this, but the key is to trade options. I made 244% in 2 months off only 3 trades. Won another competition last semester in my investment analysis class as well This is exactly how I started, starting a simulation account on the CBOE website just to see what situation was profitable because it was all greek to me. Actually after learning the greeks, I realize that site was worse and eventually read some books and got better tools. The screenshot you have is telling you the strikes, but unfortunately they are showing you the technical name of the contract on the exchanges. For example, just like you type in AAPL to buy shares of AAPL stock, you can type in VIX1616K16E to get that one particular contract, expiration and strike. So lets break it down just by inferring, because this is what I just did with that picture: You know the current price of VIX, $17.06 Calls expiring November 16th, 2016:  What is changing? SYMBOL / YEAR / EXPIRATION DAY / STRIKE / OPTION-STYLE (?) So knowing that in the money options will be more expensive, and near the money options will be slightly cheaper, and out the money will be even cheaper, you can see what is going on, per expiration. One answer in four days tells you this is a niche, else there should be many replies by now.  The bible is McMillan on Options Note - I link to the 1996 edition which starts at 39 cents, the latest revision will set you back $30 used. The word bible says it all, it offers a great course in options, everything you need to know. You don't get a special account for option trading. You just apply to your regular broker, so depending what you wish to do, the amount starts at   You sell calls against stock you own in your IRA. You see, selling covered calls always runs the risk of having your stock called away, and you'd have a gain, I'd hope. By doing this within the IRA, you avoid that.  Options can be, but are not always, speculative. Covered calls just change the shape of your return curve. i.e. you lower your cost by the option premium, but create a fixed maximum gain. I've created covered calls on the purchase of a stock or after holding a while depending on the stock. Here's the one I have now: MU 1000 shares bought at $8700, sold the $7.50 call (jan12) for $3000.  Now, this means my cost is $5700, but I have to let it go for $7500, a 32% return if called. (This was bought in mid 2010, BTW.) On the flip side, a drop of up to 35% over the time will still keep me at break even. The call seemed overpriced when I sold it. Stock is still at $7.20, so I'm close to maximum gain. This whole deal was less risky than just owning one risky stock. I just wrote a post on this trade Micron Covered Call, using today's numbers for those actually looking to understand this as new position. (The article was updated after the expiration. The trade resulted in a 42% profit after 491 days of holding the position, with the stock called away.) On the other hand, buying calls, lots of them, during the tech bubble was the best and worst thing I did. One set of trades' value increased by a factor of 50, and in a few weeks blew up on me, ended at 'only' triple. I left the bubble much better off than I went in, but the peak was beautiful, I'd give my little toe to have stayed right there. From 99Q2 to 00Q2, net worth was up by 3X our gross salary. Half of that (i.e. 1.5X) was gone after the crash. For many, they left the bubble far far worse than before it started. I purposely set things up so no more than a certain amount was at risk at any given time, knowing a burst would come, just not when. If nothing else, it was a learning experience.

Matthew - what was the stock price and strike price of the option when you did this? I've never seen an at-the-money strike with only a month to run have a price 25% of the underlying stock. Jaydles covers the variables really well in his answer. If you can afford the cost and risk of 100 shares of stock, then just sell a put option.  If you can only afford a few shares, you can still use the information the options market is trying to give you -- see below. A standing limit order to buy a stock is essentially a synthetic short put option position. [1]  So deciding on a stock limit order price is the same as valuing an option on that stock. Options (and standing limit orders) are hard to value, and the generally accepted math for doing so -- the Black-Scholes-Merton framework -- is also generally accepted to be wrong, because of black swans. So rather than calculate a stock buy limit price yourself, it's simpler to just sell a put at the put's own midpoint price, accepting the market's best estimate. Options market makers' whole job (and the purpose of the open market) is price discovery, so it's easier to let them fight it out over what price options should really be trading at. The result of that fight is valuable information -- use it. Sell a 1-month ATM put option every month until you get exercised, after which time you'll own 100 shares of stock, purchased at: This will typically give you a much better cost basis (several dollars better) versus buying the stock at spot, and it offloads the valuation math onto the options market.  Meanwhile you get to keep the cash from the options premiums as well. Disclaimer: Markets do make mistakes.  You will lose money when the stock drops more than the option market's own estimate. If you can't afford 100 shares, or for some reason still want to be in the business of creating synthetic options from pure stock limit orders, then you could maybe play around with setting your stock purchase bid price to (approximately): See your statistics book for how to set ndev -- 1 standard deviation gives you a 30% chance of a fill, 2 gives you a 5% chance, etc. Disclaimer: The above math probably has mistakes; do your own work.  It's somewhat invalid anyway, because stock prices don't follow a normal curve, so standard deviations don't really mean a whole lot.  This is where market makers earn their keep (or not). If you still want to create synthetic options using stock limit orders, you might be able to get the options market to do more of the math for you. Try setting your stock limit order bid equal to something like this: Where put_strike is the strike price of a put option for the equity you're trading.  Which option expiration and strike you use for put_strike depends on your desired time horizon and desired fill probability.  To get probability, you can look at the delta for a given option.  The relationship between option delta and equity limit order probability of fill is approximately: Disclaimer: There may be math errors here.  Again, do your own work. Also, while this method assumes option markets provide good estimates, see above disclaimer about the markets making mistakes. Intuitive? I doubt it. Derivatives are not the simplest thing to understand.  The price is either in the money or it isn't. (by the way, exactly 'at the money' is not 'in the money.') An option that's not in the money has time value only. As the price rises, and the option is more and more in the money, the time value drops. We have a $40 stock. It makes sense to me that a $40 strike price is all just a bet the stock will rise, there's no intrinsic value. The option prices at about $4.00 for one year out, with 25% volatility. But the strike of $30 is at $10.68, with $10 in the money and only .68 in time premium. There's a great calculator on line to tinker with.  Volatility is a key component of options trading. Think about it. If a stock rises 5%/yr but rarely goes up any more or less, just steady up, why would you even buy an option that was even 10% out of the money? The only way I can describe this is to look at a bell curve and how there's a 1/6 chance the event will be above one standard deviation. If that standard deviation is small, the chance of hitting the higher strikes is also small.  I wrote an article Betting on Apple at 9 to 2 in which I describe how a pair of option trades was set up so that a 35% rise in Apple stock would return 354% and Apple had two years to reach its target. I offer this as an example of options trading not being theory, but something that many are engaged in. What I found curious about the trade was that Apple's volatility was high enough that a 35% move didn't seem like the 4.5 to 1 risk the market said it was. As of today, Apple needs to rise 13% in the next 10 months for the trade to pay off. (Disclosure - the long time to expiration was both good and bad, two years to recover 35% seemed reasonable, but 2 years could bring anything in the macro sense. Another recession, some worldwide event that would impact Apple's market, etc. The average investor will not have the patience for these long term option trades.) Robert is right saying that options' prices are affected by implied volatility but is wrong saying that you have to look at the VIX index. For two reasons:  1) the VIX index is for S&P500 options only. If you are trading other options, it is less useful. 2) if you are trading an option that is not at the money, your implied volatility may be very different (and follow a different dynamics) that the VIX index.  So please look at the right implied volatility.  In terms of strategy, I don't think that not doing anything is a good strategy. I accept any point of view but you should consider that option traders should be able to adjust positions depending on market view.  So you are long 1 call, suppose strike 10. Suppose the underlying price at the time of entry was 10 (so the call was at the money). Now it's 9.  1) you still have a bullish view: buy 1 call strike 9 and sell 2 calls strike 10. This way you have a bull call spread with much higher probability of leading to profit. You are limiting your profit potential but you are also reducing the costs and managing the greeks in a proper way (and in line with your expectations).  2) you become bearish: you can sell 1 call strike 9. This way you end up with a bear call spread. Again, you are limiting your profit potential but you are also reducing the costs and managing the greeks in a proper way (and in line with your expectations). 3) you become neutral: buy 1 call strike 8 and sell 2 calls strike 9. This way you end up with a call butterfly. You are almost delta neutral and you can wait until your view becomes clear enough to become directional. At that point you can modify the butterfly to make it directional.  These are just some opportunities you have. There is no reason for you to wait. Options are eroding contracts and you must be fast and adjust the position before time starts eroding your capital at risk.  It's true that buying a call doesn't make you loose more than the premium you paid, but it's better to reduce this premium further with some adjustment. Isn't it?  Hope that helps. :) The liquidity is quite bad. I have seen open Intrest drop from thousands to zero.  Theta and the lack of liquidity are strong reasons not to buy options. Instead, consider selling them.  They say that most Option purchases expire worthless. Why is this so? Because hedge funds buy those out-of-the-money puts in case their position goes against them (like insurance).  Make money selling insurance. No one makes money buying insurance. This is a snapshot of the Jan '17 puts for XBI, the biotech index.  The current price is $65.73. You can see that even the puts far out of the money are costly. The $40 put, if you get a fill at $3, means a 10X return if the index drops to $10. A 70X return for a mild, cyclic, drop isn't likely to happen.  Sharing youtube links is an awful way to ask a question. The first was far too long to waste my time. The second was a reasonable 5 minutes, but with no example, only vague references to using puts to protect you in bad years.  Proper asset allocation is more appropriate for the typical investor than any intricate option-based hedging strategy. I've successfully used option strategies on the up side, multiplying the returns on rising stocks, but have never been comfortable creating a series of puts to hit the jackpot in an awful year. Rate of return is (Current value - initial value) divided by initial value. Buy $10,000 worth of put options and sell them for $15,000, and your rate of return is 0.5, or 50%. "When you buy a put option, you're buying the right to sell stock at the ""strike"" price. To understand why you have to pay separately for that, consider the other side of the transaction. If I agree to trade stock for money at above market rates, I need to make up the difference somewhere or face bankruptcy.  That risk of loss is what the option price is about. You might assume that means the market expects the price of AMD to fall to 8.01 from it's current price of 8.06 by the option expiration date. But that would also mean call options below the market price is worthless. But that's not quite true; people who price options need to factor in volatility, since things change with time. The price MIGHT fall, and traders need to account for that risk. So 1.99 roughly represents the probability of AMD rising to 10. There's probably some technical analysis one can do to the chain, but I don't see any abnormality of AMD here." The option commissions with IB for trading in the US market are between $0.25 to $0.70 per contract. However if you are looking to trade in Canada, where you are from, their option commission for Canada are $1.50 per contract (as you mention in your question). Note that each contract is for 100 shares, so if you wanted to trade the equivalent of 1000 shares, you would need to trade 10 contracts, so you would have to multiply the above commissions by 10 to get your final costs. (i.e. $2.50 to $7.00 in the US and $15.00 in Canada).
