In this series, I have been using the stock of General Electric as an example. Here is its chart as it appeared on January 13:
We were looking at this as a bullish example, discussing which expirations to choose for call options.
In the last paragraph of part 3, I said:
Today we'll look at that further.
This is a chart of GE as of today, January 20, 2016:
The area of demand that we had identified earlier from $27.48 to $28.09 had so far held up. Coincidentally (or not), the lowest price reached before a bounce today was exactly $27.48, the lower bound of our previously identified demand zone. If we had the nerve for it, this was still a possible bullish play.
The two simplest possible option trades for a bullish situation are buying call options or selling short put options. We discussed buying calls last time and explained why we would want to look for options with an expiration a few months away when buying.
Note the indicator in the bottom of the above chart. This is Implied Volatility, which is an indication of over- or under-pricing of options. The current reading was quite high indicating that options were expensive. When that is the case, then being a short seller of options, rather than a buyer, is indicated.
Let's say that we decided selling put options was out best choice. The plan would be to collect money for selling the options now to people who believed that GE was going lower; and then wait for the options to become worthless when GE did not go lower.
When we use this kind of plan, we want the options to be in the last few weeks of their life. That is when their value drops fastest. Remember that when buying calls we specifically did not want to own the options in the last few weeks of their life, and for the same reason. A good time to be short is a bad time to be long.
Since the February cycle ends on February 19, thirty days away, that would be a good choice for an expiration date.
For strike prices, we had a couple of alternatives. The 27 strike would be a bold choice. The February 27 puts could be sold for about $.60 per share. The investment required would be a $27 per share cash deposit. A sixty cent return on $27.00 is about a 2.2% return in a month, or 26.7% annualized. This would be our return on investment as long as GE was not below $27 on February 19. If it was lower than that, then we would be forced to pay $27 a share for it. After deducting the $.60 received for the puts, our net cost would be $26.40 per share, which would be our break-even price.
Using the near-term puts in this situation would give us a greater profit per day, as all options lose their time value at an ever-increasing rate. The March $27 puts, for example, with 57 days to go, could be sold for about $.91. That was a daily rate of return of $.91 / 57 = $1.59 per day. The February 27 puts described above, by comparison, would make $.60 in 30 days, or exactly $2.00 per day.
The shorter life of the near-term options also means that there is less time for the trade to go wrong. With short option trades, we want the clock to run out without the stock passing the strike price. The less time there is the better chance we have.
In terms of strike price selection, our second more conservative alternative was to sell puts at a $25 strike price. That would put the strike below the next lower level of demand ($24.79-25.24 on the chart). The February $25 puts could be sold for about 25 cents, which was one percent of the strike price. Our return would thus be 1% in a month, or 12% annualized (If GE did not drop below $25).
With the $25 puts, if GE should drop from its current level, it would have to fall all the way to $25 before our maximum profit was threatened. In the worst case, we would own the stock at a net cost of $25.00 - $.25 = $24.75 per share.
Whether we choose to be conservative or aggressive in selecting our strikes, the right choice of expirations is also crucial. The basic rule is to buy longer expirations, but sell shorter expirations. This allows us to be hurt the least (in the case of long options) or helped the most (in the case of short options) by the inexorable decay of time value.
