I moved this discussion out of the short term thread.
I was looking to the option chain of SCTY this morning and I had an idea that probably has some flaw in it, but I can't find it. The problem is that normally you can have a high risk investment that has upside and downside, or you can have a low risk investment with a low downside but also a limited upside, but can never have the best of both worlds. But this idea seems to have a maximum loss of $1050,00 and a maximum upside of $7950,00.
You can sell a $24,00 Jan 2017 put for SCTY for $8,15 and buy a $21,00 Jan 2017 put for SCTY for $5,50. This means that you have a maximum loss of $3,00, but you already have gained $2,65. So your maximum loss is $0,35 (or 13,2% of your maximum gain).
... ignoring the bit about converting to TSLA...
...will be more than 13,2%, this should be a good deal. Or not?!
I am quite confused at the moment, but if I haven't made a logical misstep this could be quite a good opportunity for those who think that the deal will go through and TSLA won't plummet in the next two quarters.
I've never actually done complicated options trades like this. Actually this is relatively simple spread compared to people who do iron condors etc, but my point is that my options trades are usually one-sided. But your example piqued my interest, and I have a spare afternoon.
First, I tried to reproduce your actual numbers. Now, my broker is ETrade, and maybe the quotes are broker specific. And, I'm completely ignoring the TSLA part of your logic above, just talking about the raw SCTY trade.
The first thing is that your $8.15 was the last trade of the $240 puts. However, the Bid/Ask is $6.80/$7.80. That is, the stock moved without the options trading again. Realistically you might get $7.30 for this put (the average of the bid/ask spread).
The $21 puts did trade. The b/a spread is $5/$6, last trade $5.50 as you show.
Above, you calculate maximum risk as $3 (which is the difference between the two strike prices) less $1.80 (the money you already got), so the maximum loss is $1.20. The maximum return is when you get to keep all of that $1.80. So your maximum loss is actually 67% of your maximum gain. Failing to take into account the lack of trading of the write-side option is where your calculation went wrong. You would be right if you could actually execute the trades as you wrote them, but without further movement in the underlying stock you'll never be able to do that. Actually, movement in SCTY will tend to move both ends of the trade, so you'll probably never be able to do it. In fact, even my trade might be impossible.
This is one of my big problems with "paper trading", which a lot of people recommend to beginners. It is easy to convince yourself that you'd have made a fortune if only you had real money, but in reality either the trades wouldn't ever have happened or you'd get the timing wrong or something. All you can count on is that you'll never make as much as you thought you would. And the fortune you make may be negative
.
The good thing about this is that, like you, I followed the link to
optionsprofitcalculator.com (thanks
@MitchJi) and learned a lot about how the time value affects early exit from a trade like this. Suppose the deal goes through and on July 30 SCTY goes instantly to $26. You could probably exit both puts and get 12.5%, in only 3 weeks. Of course you'd make a lot more by ignoring the lower strike, and just selling the at-the-money puts, but then your downside insurance is all gone. If the deal tanks and SCTY goes down to $21, I can probably exit for only 15%. Note the disparity... time value works against us here.
The next good thing is that I knew ETrade allowed me to do these kinds of trades, but I'd never tried one. The way it works is I enter both ends of the spread, but instead of pricing the individual trades I just say "I want to get $2" (a little up from $1.80). This makes my downside $1 and upside $2, for a slightly better outcome. Of course the trade might never execute. I put it in for 10 contracts of each. We'll see, and I'll report back.
