I think MF is a good guide, but its still up to you to weed out whats good and not.
I think too many people expect the MF to be a get rich quick scheme. Yes, the MF has a pretty good positive record, but playing stock is like gambling in a casino.
MF should not be consider an guide to getting rich. MF should only be used as a general guide to steer you towards potential good stocks so you won’t have to weed through hundreds of stocks with your limited knowledge.
