There is one thing of which I can assure you. If good performance of the fund is even a minor objective, any portfolio encompassing one hundred stocks (whether the manager is handling one thousand dollars or one billion dollars) is not being operated logically.

The man claiming to be a financial alchemist may become rich. But gullible investors rather than business achievements will usually be the source of his wealth.
