Calculating profits on a covered call. What method do you use?
yes, you are double counting. Your profit is between ($7.25 and $8) OR ($7.75 and $8.50). in other words, you bought the stock at $7.75 and sold at $8.00 and made $0.50 on top. Profit =  $8.00-$7.75+$0.50 (of course all this assumes that the stock is at or above $8.00 when the option expires. If it's below, then your profit = market price - $7.75 + $0.50 by the way the statement  won't call me away until the stock reaches $8.50 is wrong. They already paid $0.50 for the right to buy the stock at $8.00. If the stock is $8.01 on the day of expiration your options will be executed(automatically i believe). "at $8.50:  total profit = $120.00 *basis of stock, not paid in cash, so not included in ""total paid"" at $8.50: total profit = $75.00"
"The heart of the question is: why can't Bill just pay whatever he owes based on his income in that quarter? If Q2 is gang busters, he'll increase his tax payment. Then if Q3 is surprisingly slow, he'll pay less than he paid in Q2. I think what's most interesting about this question is that the other answers are geared towards how a taxpayer is supposed to estimate taxes. But that's not my objective -- nor is it Bill's objective. My [his] real objective is:  In other words, the answer to this question either needs to deal with not overpaying, or it needs to deal with mitigating the underpayment penalty. AFAICT, there are 2 solutions: Solution 1 Figure your estimated taxes based on last year's tax. You won't owe a penalty if your withholding + estimated tax payments in each quarter are 25% or more of your previous year's tax liability. Here's the section that I am basing this on: http://www.irs.gov/publications/p505/ch04.html Minimum required each period.   You will owe a penalty for any 2011 payment period for which your estimated tax payment plus your withholding for the period and overpayments for previous periods was less than the smaller of: 22.5% of your 2011 tax, or 25% of your 2010 tax. (Your 2010 tax return must cover a 12-month period.) Solution 2 Use the ""Annualized Income Installment Method"". This is not a method for calculating estimated taxes, per se. It's actually a method for reducing or eliminating your underpayment penalty. It's also intended to assist tax payers with unpredictable incomes. If you did not receive your income evenly throughout the year (for example, your income from a shop you operated at a marina was much larger in the summer than it was during the rest of the year), you may be able to lower or eliminate your penalty by figuring your underpayment using the annualized income installment method. Emphasis added. In order to take advantage of this, you'll need to send in a Schedule AI at the end of the year along with a Form 2210. The downside to this is that you're basically racking up underpayment penalties throughout the year, then at the end of the year you're asking the IRS to rescind your penalty. The other risk is that you still pay estimated taxes on your Q2 - Q4 earnings in Q1, you just pay much less than 25%. So if you have a windfall later in the year, I think you could get burned on your Q1 underpayment." "OK, reading between the lines here it looks like the services offered by your company are of an ""adult"" (possibly illegal?) nature and that this individual has actually paid you in full for the services rendered up to this point. The wrinkle here is that you say that you've been offered large cash ""gifts"" in return for unspecified future favours, but that your client hasn't provided a real Paypal account to do so. When you pressed him on it, he sent a fake email and invented a ""financial adviser"" to fob you off, then hasn't contacted you  since. It's pretty clear that he hasn't got any intention of making these payments to you. What you're now proposing to do is to use his known banking details to collect money to cover those verbal promises. In pretty much every part of the world, that's a crime. Without a written agreement to use that payment method for those promises, he could easily call the police and have you arrested for theft of funds. The further wrinkle is that his actions (claiming to have made payment via paypal, forged email headers, etc) strongly suggest that this individual is involved in cyber-crime and may well have used a fake bank account to pay for your initial services.  The bottom line here is that you need real legal advice, from an actual lawyer." Gifts from your parents are not treated as income for tax purposes. You should not include that in your subsidy calculation. If you are here on a student-visa and have been in the US for less than 5 years, then you are considered a non-resident alien, and you are not required to buy a qualified plan through the insurance marketplace. You might be able to get a cheaper student plan through your school, but the subsidy might be enough that it's still worth it when calculated correctly. If you are a resident-alien or you are a citizen of the US, then you are required to get coverage, though you can choose not to purchase coverage and pay the tax for not having creditable coverage. That tax cannot be collected by the IRS unless you have already had federal tax withheld. They can only confiscate your tax return money to recoup that money. I don't have enough information to recommend one way or the other what you should do, but I would bet that if you recalculated your subsidy without including your parents income it would cover the majority of the cost. You should also consider applying for Medicaid if you meet the eligibility requirements in your state. I think you need to be very careful here. Covered calls don't reduce risk or increase performance overall. If they did, every investment manager would be using them. In a typical portfolio, over the long term, the gains you give up when your stock goes beyond the strike of your calls will negate the premiums you receive over time. Psychologically, covered calls are appealing because your gains happen over a long period and this is why many people suggest it. But if you believe the Black-Scholes model (used for pricing options) this is what the model predicts over the long term - that you won't do any better than just holding stock (unless you have some edge other traders don't). Now you say you want to reduce diversification and raise your risk. Keeping in mind that there is no free lunch, there are several ways to reduce your risk but they all come at a price. For simplicity, there are three elements to consider - risk, potential gain and cash. These are tradeoffs and you can't simultaneously make them all favorable. You must trade one or more of them to gain in the others. Let's say you wanted to concentrate into a few stocks... how could you counteract the additional risk? 1) Covered calls: very popular strategy usually intended (erroneously) for increasing returns. You get the bonus of cash along with marginally less risk. But you give up a substantial amount of potential return. You won't have blowout returns if you do this. You still face substantial risk. 2) Collar your stock: You sell a covered call while using the cash from the sale to buy puts for protection. You give up potential gains, you're neutral on cash but gain significantly on reducing risk.  3) Use calls as proxy for stock: You don't hold stock but only calls in equivalent delta to the stock you would have held. Substantially lower risk while still having potential gain. Your tradeoff is the cash you have to pay for the calls. When using this, one must be very, very careful not to overleverage.  4) Puts as protection for stocks: This is basically the same as #3 in tradeoffs. You won't overleverage and you also get dividends. But for the most part it's the same. These are the main ways to reduce the risk you gain by concentrating. Options themselves are far broader. But keep in mind that there is no free money. All these techniques involve tradeoffs that you have to be aware of. You are NOT responsible for liquidating the position.  You will either end up retaining your 100 sh. after expiration, or they will be called away automatically. You don't have to do anything.  Extending profitability can mean different things, but a major consideration is whether or not you want to hold the stock or not.  If so, you can buy back the in-the-money call and sell another one at-the-money, or further out. There are lots of options. This link does it ok:  http://investexcel.net/1979/calculate-historical-volatility-excel/ Basically, you calculate percentage return by doing stock price now / stock price before.  You're not calculating the rate of return hence no subtraction of 100%.  The standard is to do this on a daily basis: stock price today / stock price yesterday. The most important and most misunderstood part is that you now have to analyze the data geometrically not arithmetically.  To easily do this, convert all percentage returns with the natural log, ln(). Next, you take the standard deviation of all of those results, and apply exp().  This answers the title of your question. For convenience's sake, it's best to annualize since volatility (implied or statistical) is now almost always quoted annualized.  There are ~240 trading days each year.  You multiply your stdev() result by (240 / # of trading days per return) ^ 0.5, so if you're doing this for daily returns, multiply the stdev() result by 240^0.5; if you were doing it weekly, you'd want to multiply by (240 / ~5)^0.5; etc.  This is your number for sigma.  This answers the intent of your question. For black-scholes, you do not convert anything back with exp(); BS is already set up for geometric analysis, so you need to stay there. The reason why analysis is done geometrically is because the distribution of stock returns is assumed to be lognormal (even though it's really more like logLaplace). I often sell covered calls, and if they are in the money, let the stock go. I am charged the same fee as if I sold online ($9, I use Schwab) which is better than buying back the option if I'm ok to sell the stock.  In my case, If the option is slightly in the money, and I see the options are priced well, i.e. I'd do another covered call anyway, I sometimes buy the option and sell the one a year out.  I prefer to do this in my IRA account as the trading creates no tax issue. To calculate you take the Price and divide it by the Earnings, or by the Sales, or by the Free Cash Flow. Most of these calculations are done for you on a lot of finance sites if the data is available. Such sites as Yahoo Finance and Google Finance as well as my personal favorite: Morningstar
