Multioption
I have used the deep in the money option directional trading strategy for many years.
Although often I go much deeper in the money to get a delta of close to 100 with lower theta.

Let's do a quick calculation:
Wed 10/26 after closing I looked at AAPL:
http://www.elitetrader.com/vb/showthread.php?s=&postid=879941#post879941
My assessment was to enter short at closing (AAPL at $57.03) with a stop loss at $60 and an exit target at $53.7 in 1-2 weeks. IV being relatively low 35-36% I decided to buy the Nov 60 put, QAAWL.
Let's compare this with the Nov 65 put, QAAWM (next strike deeper ITM).
To size my position I assume an account of $100k, and I'm willing to risk 1% for this position $1,000.
Quotes as of 10/26:
- QAAWL 3.7 / 3.9
- QAAWM 8 / 8.2
Worst case for my position:
- AAPL at $60
- IV 25% drop
- 2 weeks from opening
Using a B-S model this means:
- a drop of $2.8 for QAAWL
- a drop of $3 for QAAWM
With $1,000 I can buy:
- 3.53 contracts QAAWL
- or 3.24 contracts QAAWM
For the sake of this comparison I'll not round down the number of contracts to 3, as I'd do if I opened this position.
I attached the graph of the 3.53 QAAWL contracts, and the graph of the difference 3.53 QAAWL - 3.24 QAAWM contracts (a backspread with a ratio very close to 1, almost a bull put spread).
What do I read here?
- QAAWL position will make $800 if AAPL drops to $53.7 (green line), and lose $1,000 if stopped at $60 12 days before expiration (red line)
- QAAWM position will make $150 more than QAAWL if AAPL drops to $53.7 12 days before expiration, and up to $200 more if AAPL will be about $56 at that time. If stopped at $60 QAAWL will outperform QAAWM with $25 to $125.
- QAAWL ties up $1,377 (ask $3.9), while QAAWM (ask $8.2) ties up about twice as much $2,657; this represents also the absoulte maximum risk when AAPL gaps up through my stop loss, and I lose my whole investment.
- QAAWM offers up to 25% higher gain, with an investment 100% higher.
In conclusion I'll open the QAAWL position: less max risk, especially because AAPL is in a strong uptrend and I'm playing against it.
You may want to go after the up to 25% higher absolute return (for the same $1,000 stop loss), if so you should open the QAAWM position.
Slippage doesn't seem a factor here.
Also, even deeper in the money puts don't offer any advantage, and they tie more capital and increase the "black swan" risk.
