An equity strategy
Own calls + cash adjacent investments.
Model the risk profile.
Make money
Don't overthink it.
Iran Play
IMO, Iran has no hope. Therefore I'm investing based on a quick loss for them. Its working.
Double Eagle
I found a 'cash adjacent' investment to enhance my returns. A stock, ticker DEA. It pays 8%, plus nice capital gains potential. Two sources of profits.
Oppenheimer Fund, 1987
Oppenheimer funds recorded exceptional performance in 1987 despite the October market crash, with the Oppenheimer Ninety-Ten Fund leading as one of the best-performing mutual funds of the year with a return of +94.77% through December 23, 1987.
It was 40 years ago. I was impressionable. I was impressed.
1. You can't insure excellent results normally. You can always insure before a catastrophic loss with good results.
2. You can manage "insurance" costs.
3. You can't implement an insurance strategy passively with good results usually.
Options to Reduce Risk
Its obvious that a stock + a Put is less risky then just the stock.
Likewise a `call is simply the piece of a stock that can only go up.
To emulate a stock portfolio, sell the stock, and buy an exactly equivalent number of calls.
You reduced risk of loss.

Call Options
A stock can be decomposed into simple vectors, a scalar, Strike Price, and an expiration date.
Call Option: A vector that begins at the strike price, ends at the termnal price, and extends upward until expiration.
Put Option: A vector that begins at the strike price, ends at the termnal price, and extends downward until expiration. It's value is -price.
Strike Price: A scalar representing the starting price of the options.
Stock=Call+Strike(Cash)-Put
Often referred to as Put/Call Parity.
Most important: Stock+Put=Call+Cash.
