What is a straddle?
"A straddle is an options strategy in which one ""buys"" or ""sells"" options of the same maturity (expiry date) that allow the ""buyer"" or ""seller"" to profit based on how much the price of the underlying security moves, regardless of the direction of price movement. IE: A long straddle would be: You buy a call and a put at the same strike price and the same expiration date. Your profit would be if the underlying asset(the stock) moves far enough down or up(higher then the premiums you paid for the put + call options) (In case, one waits till expiry) Profit = Expiry Level - Strike Price - (Premium Paid for Bought Options) Straddle" "Came across this very nice video which explains the ""Long Straddle"". Thought will share the link here: http://www.khanacademy.org/finance-economics/core-finance/v/long-straddle"
Long Straddle:  \\/  Assuming you're trying to straddle the spot price, it will be more expensive to set up than a strangle as options strikes near the spot are more costly. Any price movement will regain against what was spent to acquire the options.  Long Strangle:  \\_/  Assuming you're trying to strangle the spot price, it will be less expensive to set up than a straddle as the options strikes are away from the spot.  It will require a larger price movement than the straddle to begin to regain value against what you spent, as there is a dead zone between the strikes where both expire worthless.  The / is the gain from a price movement up from the increase in value of calls; the \\ is the gain from a price movement down from the increase in value of puts.

"Support and resistance points indicate price levels where there have been a large amount of trading activity, usually from institutions, that tend to stabilize the price of a stock. Support is a temporary FLOOR, where people have been buying in large quantities. That means there's a good chance that the stock won't go below this level in the near term. (But if it does, watch out.) Resistance is a temporary CEILING where people have been selling. When the stock price hits this level, people tend to sell, and push it back down. Until there are ""no more"" sellers at this level. Then the price could skyrocket if there is enough buying." G spread - you have a 5.5 year bond, you take your yield minus the yield on the 5.5y point (interpolated) of the benchmark sovereign curve. Think of G = Government.      I Spread - same as G Spread but you use the relevant Swap Curve. E.g. USD bond, compare against the USD Swaps curve. I = interpolated.      Z Spread - stands for zero volatility curve spread. You strip the swaps curve to get zero rates (i.e. Zero coupon rates for each tenor), then find the constant spread on top of each part of the curve's zero rates to arrive at your bond's yield.      In G and I Spread, you're basically discounting the bond's cash flows using one rate (i.e. The interpolated yield on the curve). With Z Spread, you're discounting using the entire portion of the curve that's relevant to your bond's maturity. The mechanism is allowing insertion of 3 butyl rubber seals in the window between the frame and the opening sash. It has an external seal, mid window, and inner seal. Due to its constructional make-up many non-tilt turn manufacturers are limited to one or two seals. "The question mentions a trailing stop. A trailing stop is a type of stop loss order. It allows you to protect your profit on the stock, while ""keeping you in the stock"". A trailing stop is specified as a percentage of market price e.g. you might want to set a trailing stop at 5%, or 10% below the market price. A trailing stop goes up along with the market price, but if the market price drops it doesn't move down too. The idea is that it is there to ""catch"" your profit, if the market suddenly moves quickly against you. There is a nice explanation of how that works in the section titled Trailing Stops here. (The URL for the page, ""Tailing Stops"" is misleading, and a typo, I suspect.)" Depending on the structure of you're portfolio, it could be that your portfolio is delta neutral to take advantage of diminishing time value on options, short straddles/strangles would be an example. The main reason is that you move from the linear payoff structure to a non-linear one. This is called convexity in finance. With options you can design a payoff structure in almost any way to want it to be. For example you can say that you only want the upside but not the downside, so you buy a call option. It is obvious that this comes at a price, the option premium. Or equivalently you buy the underlying and for risk management reasons buy a put option on top of it as an insurance. The price of the put could be seen as the insurance premium. You can of course combine options in more complicated ways so that you e.g. profit as long as the underlying moves strongly enough in either direction. This is called a straddle. Activist Investor is the entrenched capitalists fake news meme. Trump wants to pass a law that says shareholders don't even get a vote until they pass a certain threshold on ownership % of a company so they can keep all the little people from having any say. Ownership isn't really ownership unless you're rich I guess. Democracy bad! Freedom! America! Basic arbitrage is the (near-)simultaneous purchasing and selling of things that are convertible.   The classic example is the international trading of equities. If someone in London wants to purchase a hundred shares of Shell for 40 GBP ea. and someone in New York wants to sell you a hundred shares of Shell for 61 USD ea., you can buy the shares from the guy in New York, sell them to the guy in London and convert your GBP back in to USD for a profit of $41.60 minus fees.  Now, if after you buy the shares in New York, the price in London goes down, you'll be left holding 100 shares of Shell that you don't want. So instead you should borrow 100 shares in London and sell them at the exact same time that you buy the shares in New York, thus keeping your net position at 0. In fact, you should also borrow 4000GBP and convert them to USD at the same time, so that exchange rate changes don't get you. Honestly this sounds like a bug. In the early days of HFT, quote stuffing looked like this, but everyone created anti manipulation algos that do Fourier transforms to catch that kind of behavior. Modern manipulation is much cleverer than this. Source: I have designed anti manipulation algos for a HFT firm. Bootstrap has been a verb for a very long time, and you've used it as such all your life, or at the very least it's short form: booting.

This is a ""depth chart"" that I pulled from google images, specifically because it doesn't name any security.  On the left you have all of the ""bids"" to buy this security, on the right you have the ""asks"" to sell the security.  In the middle you have the bid/ask spread, this is the space between the highest bid and the lowest ask.  As you can see you are free to place you order to the market to buy for 232, and someone else is free to place their order to the market to sell for 234.  When the bid and the ask match there's a transaction for the maximum number of available shares.  Alternatively, someone can place a market order to buy or sell and they'll just take the current market price. Retail investors don't really get access to this kind of chart from their brokers because for the most part the information isn't terribly relevant at the retail level." If it wasn't true before I learned it than how was I taught it in the first place e where I would believe it?   Do you know what gish galloping is? I'm perfectly open to other viewpoints but I'm not going to watch two long videos. Can you just make the points in these vids?
