I'm a Due-Diligence(DD) Fanatic. I NEVER EVER trade a position without serious DD. It all starts and ends with a call to Investor Relations(IR).
I take tremendous pride in finding things out about companies that others are afraid to ask...;)
Invest in stocks that have high earnings beat or miss and hold them for a short term to several months using call or put options. Also use covered calls to make income on my current holdings. I also invest in biotech stocks.
