What do you consider long term? A few years? Ive already been doing it for 10 months and have a profit of 138%. Now, can I increase my position sizes by 100 fold and it still work? I have no idea. Maybe not. Maybe that's why the big boys don't do it. They cant trade large enough positions. A lot of the options that I'm trading have small amounts of open interest. I am currently short 8 MA June 615 puts and long 8 July 615s. The open interest on both of those puts is 8 so these are the only trades in those strikes. Others I have less than 1% of the open interest so who knows.
I think there is something to be said for what Utrecht is saying. Plenty of options being traded have very small open positions and probably aren't interesting enough for professional money traders, although maybe computerized trader programs buy and sell individual contracts, I don't know.
When I first learned about options and dabbled in trading them was in my early 20s. All my co workers who were in their 20 and 30s we all bought options (either calls or puts) nobody had the capital or the inclination to write options. What fun is it to collect $2 by writing an option when you can make $20 buying a OTM call and seeing the stock shoot up in couple of months.
So I think the number of individual trader who write options is much smaller than the number of individual who want to buy them. This imbalance I think creates an opportunity to make a profit.
Back in the 80s it was way more expensive to trade options than it is today and the 5+% commission (including the larger spreads) wiped out any potential of profit. Now days the cost are pretty small a percent or so round trip.
Still in the case of SPY options the volumes are high and there is little doubt we are competing with the big boys, so I am less convinced that there is any advantage to be found. My experience writing weekly puts was there probably some Alpha, but the tax hassles (even though turbo taxes imported the trades I still want to verify them) and trading hassles weren't worth the extra few hundred dollars. When I looked at doing the same thing in IRA, the logistical hassle outweigh any advantage.
Regarding you mastercard options trade. It looks like you are paying $3.50 or so for buying a deep in the money put. Is there some reason you think the stock will drop in July and not in June
