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 addition of the one hundredth stock simply can't reduce the potential variance in portfolio performance sufficiently to compensate for the negative effect its inclusion has on the overall portfolio expectation.” [Warren Buffett](https://sms4smile.com/quotes/author/warren-buffett/) ## About This Quote This interpretation was drafted with AI assistance.
