Hey Kim,
To me using options to boost your returns sounds like a no-brainer for a fundamental investor.
For e.g: Sell a naked put - Stock goes down to your strike and you get assigned. Win for you because you get to purchase the stock at the price you want. If the stock goes up, you get to keep your premium. Either way, you win unless there is a huge news that crashes the stock which is highly unlikely from a probability point of view.
What am I missing here? Or as you mentioned, 99% of fundamental investors are purely the buy and hold type?
