What is a call spread and how does it work?
A bullish (or 'long') call spread is actually two separate option trades.  The A/B notation is, respectively, the strike price of each trade. The first 'leg' of the strategy, corresponding to B, is the sale of a call option at a strike price of B (in this case $165).  The proceeds from this sale, after transaction costs, are generally used to offset the cost of the second 'leg'. The second 'leg' of the strategy, corresponding to A, is the purchase of a call option at a strike price of A (in this case $145). Now, the important part: the payoff.  You can visualize it as so. This is where it gets a teeny bit math-y.  Below, P is the profit of the strategy, K1 is the strike price of the long call, K2 is the strike price of the short call, T1 is the premium paid for the long call option at the time of purchase, T2 is the premium received for the short call at the time of sale, and S is the current price of the stock.  For simplicity's sake, we will assume that your position quantity is a single option contract and transaction costs are zero (which they are not). P = (T2 - max(0, S - K2)) + (max(0, S - K1) - T1) Concretely, let's plug in the strikes of the strategy Nathan proposes, and current prices (which I pulled from the screen).  You have: P = (1.85 - max(0, 142.50 - 165)) - (max(0, 142.50 - 145)) = -$7.80 If the stock goes to $150, the payoff is -$2.80, which isn't quite break even -- but it may have been at the time he was speaking on TV. If the stock goes to $165, the payoff is $12.20. Please do not neglect the cost of the trades!  Trading options can be pretty expensive depending on the broker.  Had I done this trade (quantity 1) at many popular brokers, I still would've been net negative PnL even if NFLX went to >= $165.
"Not all call options that have value at expiration, exercise by purchasing the security (or attempting to, with funds in your account).   On ETNs, they often (always?) settle in cash.  As an example of an option I'm currently looking at, AVSPY, it settles in cash (please confirm by reading the documentation on this set of options at http://www.nasdaqomxtrader.com/Micro.aspx?id=Alpha, but it is an example of this).  There's nothing it can settle into (as you can't purchase the AVSPY index, only options on it).  You may quickly look (wikipedia) at the difference between ""American Style"" options and ""European Style"" options, for more understanding here. Interestingly I just spoke to my broker about this subject for a trade execution.  Before I go into that, let me also quickly refer to Joe's answer:  what you buy, you can sell.  That's one of the jobs of a market maker, to provide liquidity in a market.  So, when you buy a stock, you can sell it.  When you buy an option, you can sell it.  That's at any time before expiration (although how close you do it before the closing bell on expiration Friday/Saturday is your discretion).  When a market maker lists an option price, they list a bid and an ask.  If you are willing to sell at the bid price, they need to purchase it (generally speaking).  That's why they put a spread between the bid and ask price, but that's another topic not related to your question -- just note the point of them buying at the bid price, and selling at the ask price -- that's what they're saying they'll do. Now, one major difference with options vs. stocks is that options are contracts. So, therefore, we can note just as easily that YOU can sell the option on something (particularly if you own either the underlying, or an option deeper in the money).  If you own the underlying instrument/stock, and you sell a CALL option on it, this is a strategy typically referred to as a covered call, considered a ""risk reduction"" strategy.  You forfeit (potential) gains on the upside, for money you receive in selling the option. The point of this discussion is, is simply: what one buys one can sell;  what one sells one can buy -- that's how a ""market"" is supposed to work.  And also, not to think that making money in options is buying first, then selling.  It may be selling, and either buying back or ideally that option expiring worthless. -- Now, a final example.  Let's say you buy a deep in the money call on a stock trading at $150, and you own the $100 calls.  At expiration, these have a value of $50.  But let's say, you don't have any money in your account, to take ownership of the underlying security (you have to come up with the additional $100 per share you are missing).  In that case, need to call  your broker and see how they handle it, and it will depend on the type of account you have (e.g. margin or not, IRA, etc).  Generally speaking though, the ""margin department"" makes these decisions, and they look through folks that have options on things that have value, and are expiring, and whether they have the funds in their account to absorb the security they are going to need to own.  Exchange-wise, options that have value at expiration, are exercised.  But what if the person who has the option, doesn't have the funds to own the whole stock? Well, ideally on Monday they'll buy all the shares with the options you have at the current price, and immediately liquidate the amount you can't afford to own, but they don't have to.  I'm mentioning this detail so that it helps you see what's going or needs to go on with exchanges and brokerages and individuals, so you have a broader picture." It's unclear what you're asking. When I originally read your question, it seemed that you had closed out one options position and opened another. When I read your question the second time, it seemed that you were writing a second option while the first was still open. In the second case, you have one covered and one naked position. The covered call will expire worthless, the naked call will expire in the money. How your broker will resolve that is a question best left for them, but my expectation is that they will assign the non-worthless calls. Whereas, if both options expired in the money, you would be assigned and you would have to come up with the additional shares (and again, that depends on how your broker works). In general, for both cases, your net is the premiums you received, plus the difference between strike price and the price that you paid for the stock, minus any cost to close out the position. So whether you make a profit is very much dependent on how much you received for your premiums. Scenario #1: close first call, write second: Scenario #2: write covered + naked, one expires worthless Scenario #3: write covered + naked, both expire in the money Disclaimer: the SEC does not consider me a financial/investment advisor, so this is not financial/investment advice "There isn't really a generic options strategy that gives you higher returns with lower risk than an equivalent non-options strategy. There are lots of options strategies that give you about the same returns with the same risk, but most of the time they are a lot more work and less tax-efficient than the non-options strategy. When I say ""generic"" I mean there may be strategies that rely on special situations (analysis of market inefficiencies or fundamentals on particular securities) that you could take advantage of, but you'd have to be extremely expert and spend a lot of time. A ""generic"" strategy would be a thing like ""write such-and-such sort of spreads"" without reference to the particular security or situation. As far as strategies that give you about the same risk/return, for example you can use options collars to create about the same effect as a balanced fund (Gateway Fund does this, Bridgeway Balanced does stuff like it I think); but you could also just use a balanced fund. You can use covered calls to make income on your stocks, but you of course lose some of the stock upside. You can use protective puts to protect downside, but they cost so much money that on average you lose money or make very little. You can invest cash plus a call option, which is equivalent to stock plus a protective put, i.e on average again you don't make much money. Options don't offer any free lunches not found elsewhere. Occasionally they are useful for tax reasons (for example to avoid selling something but avoid risk) or for technical reasons (for example a stock isn't available to short, but you can do something with options)." &gt;IOW, everyone is perfectly free to instantaneously decide that a dollar is worth only 1/1,000,000,000th of an orange, and oranges would instantly cost a billion dollars. Oranges cost less than that not because the government sets the price of oranges, but purely because that's what the market agrees to.   This shows a profound misunderstanding of how fiat currencies work.  The demand for fiat currencies comes from the fact they are necessary to pay taxes and debts.  Other currencies/commodities will not be recognized as settlement of debts in court disputes, so they would first need to be sold onto the market in exchange for the fiat currency.  Individuals can't simply *decide* what the relative value of certain goods and services are.  The market does that, collectively via voluntary trade.  &gt;I'm explaining internal combustion for a 5-year-old, and you're calling it inaccurate and misleading because it doesn't address the sociological implications of American car-culture.   Hahah, you're confusing the oil for the gasoline! "EDIT quid keenly identified the 1:7 reverse split In May 2017.  In a 1:7 reverse split, your shares are worth 7 times as much per share but you have 1/7 the amount of shares.  A share worth $3.78 now was worth (all else being equal) $0.54 a month ago.   So a call with a $2.50 strike a month ago was well out-of-the-money, and would now be the equivalent of a call with a $17.50 strike.  A $17.50 call with a $3.78 underlying (or a $2.50 call with a $0.54 underlying) would reasonably be worth only 5 cents. So I now suspect that the quote is a stale quote that existed pre-split and hasn't been adjusted by the provider. OLD ANSWER I can find no valid reason why those calls would be so cheap.  The stock price has been trending down from its onset in 2000, so either no one expects it to be above $2.50 in a month or it's so illiquid that there's not any real data to evaluate the options.  They did pay some massive (30%) dividends in 2010 and 2012, they've been hemorrhaging cash for the past 4 years at least, and I have found at least on ""strong sell"" rating, so there's not much to be optimistic about.  NASDAQ does not list any options for the stock, so it must be an OTC trade.   With an ask size of 10 you could buy calls on 1,000 shares for $0.05, so if you can afford to lose $50 and want to take a flyer you can give it a shot, but I suspect it's not a valid quote and is something that's been manufactured by the option broker." "I look for buying a call option only at the money, but first understand the background above: Let's suppose X stock is being traded by $10.00 and it's January The call option is being traded by $0.20 with strike $11.00 for February. (I always look for 2% prize or more) I buy 100 stocks by $10.00 each and sell the option, earning $0.20 for each X stock. I will have to deliver my stocks by $11.00 (strike value agreed). No problem for me here, I took the prize plus the gain of $1.00. (continuing from item 3) I still can sell the option for the next month with strike equal or higher than that I bought. For instance, I can sell a call option of strike $10.00 and it might be worth to deliver stocks by $10.00 and take the prize. (continuing from item 3) Probably, it won't be possible to sell a call option with strike at the price that I paid for the stock, but that's not a problem. At the end of the option life (in February), the strike was $11.00 but the stock's price is $8.00. I got the $0.20 as prize and my stocks are free for trade again. I'll sell the call option for March with strike $9.00 (taking around 2% of prize). Well, I don't want to sell my stocks by $9.00 and make loss, right? But I'm selling the call option anyway. Then I wait till the price of the stock gets near the strike value (almost ATM) and I ""re-buy"" the option sold (Example: [StockX]C9 where C means month = March) and sell again the call option with higher strike to April (Example [StockX]D10, where D means month = April) PS.: At item 9 there should be no loss between the action of ""re-buy"" and sell to roll-out to the next month. When re-buying it with the stock's price near the strike, option value for March (C9) will be lower than when selling it to April (D10). This isn't any rule to be followed, this is just a conservative (I think they call it hedge) way to handle options and stocks. Few free to make money according to your goals and your style. The perfect rule is the one that meet your expectation, don't take the generalized rules too serious." The strategy looks good on paper but in reality, the 150 call will have some time value particularly if it has got some time to mature. Let us say this time value is 0.50 , so the call costs 3.50.   If the stock stays above 150 (actually above 149.50) , by the expiration of the call, you will lose this 0.50 . Then you need to keep buying calls over and over and hope one day a big down move will more than make up for all this lost premium. It is possible, but not entirely predictable. You may get lucky, but it may take many months to produce a significant move to make up for all the lost premium. If a big down move were to happen and the market had any indication of that in advance, that would be priced into the call already, so the 150 call may cost 4$ or 4.50$ if the market had wind of a big move. (a.k.a high implied volatility) A long call options spread. In this case, a bet that the USO ETF would recover to $35. You can see, I got in when USO was $28, and it's continued to drop, but it has till Jan '17 to recover. The spread is set up to give leverage, when I entered the trade, a 50% recovery would result in a 200% gain, or 3X my bet. An option spread can be bought using any two strikes, and with different payouts depending on how far out of the money the strikes are.
