I would need a long and audited track record to judge his advisory service. However...
a) the catchphrase "A Conservative Stock Options Trading Strategy Designed To Never Lose Money" is a smoking gun for any seasonned professional. He then links it to his "tip Nr 6", where he admits having losing month occasionally. oh really?
b)he sells his tips to non-pro, individuals investors, but promotes, in the "Stock Options Trading idea Of The Week" (homepage) the exotic butterfly spread, which is advanced enough to make me say confidently that it doesn't fit the profile and risk appetite of his targets.
--> save some bucks, get "Options Volatility & Pricing", Sheldon Natenberg.
