OptionHouse has a number of commission rates. If you trade in size, their $8.50 + .15 per contract makes sense. Trade smaller? Up to 5 contracts (or spreads) for $5 plus $1 for each contract might be better.
That's not bad, I probably would use the former rate. I wouldn't have >30 contracts and likely the max rate would be $13 with 30, then.
I prefer Interactive Brokers at .25 to .75 cts per contract (lower for BIG volume) with free assignment and exercise.
Yeah, I looked at IB's commission page. 0.25 is pretty good for the cheap contracts. But 0.75 is on the higher side of things. Commission would be $22.50 with 30. Free assignment/exercise is very nice, though. I have to check what it would cost at optionshouse. I'm more concerned about assignment.
I will have to start adding commissions to my spreadsheet and see the costs.
Put premiums are less than call premiums because of the carry cost of the underlying and dividends, if any. The advantage of selling puts is fewer commissions and less slippage and that can add up significantly if you're chasing income (the 3-7% that you mentioned).
I was specifically talking about short-term calls and puts, ie. weekly, so dividend does not come into play unless there is one scheduled that week.
For SPY it's quarterly. For example, the SPY $125 put for this friday closed at $1.27 . But the SPY $125 call closed at $2.04 . Quite a difference. Maybe the market just expects it to go up, even though today was a down day.
If I look at the LEAPS SPY puts and calls, the pattern gets inverted.
Jan 2014 $125 call is $17.32 . But Jan 2014 $125 put is $21.60 - much more.
The short weekly put is covered by the long term put (calendar or diagonal spread). The long term put is a substitute for the underlying. That seriously reduces risk. For that benefit, you pay a premium.
Right, it reduces risk, and also probably eliminates the return in the process, or pushes it negative ;-)
With a options, you have multiple considerations. You need to compare the risk graphs of various long legs. Because of the risk premium, it makes more sense to me to buy 1-2 month long leg rather than a LEAP with weekly diagonals. Should you be lucky enough to recover the long premium after a few successful weekly writes that expire, you could end up with an unencumbered long leg that has the potential to make a lot more than the weekly premium. Imagine what that might achieve if you were doing it on both sides and subsequently ended up with a low to no cost long strangle or straddle?
Yes, that sounds interesting, but one would have to be fairly lucky to see the market go up during the first few weeks with the writes, and then down just before the long put expires. Things can move the other way around, too.
If I buy a 1-2 month put, there are only 4-8 weeks left to make the premium back with weekly put writes.
Profit is much more likely if one doesn't buy a long put. But risk of a sudden major market slump is there. One way to protect against it is to write a way OOM put. For example writing a put at 90 cents on the dollar on SPY almost never gets assigned. I think only once over the last 4 years, in October 2008. And the shares go back above strike within the next week.
Downside is that the premium from such OOM puts is very low. Many weeks I calculated it to be actually 0 for previous weeks of low volatility. My spreadsheet rounds down all the puts I write to the lowest cent to try to account for bid/ask spreads.
I think writing the 90% OOM puts weekly earned <1% annualized. But risk was close to 0.
