“Diversification is protection against ignorance, it’s a sound approach for a novice”
But….
“Diversification makes little sense for people who know what they are doing”
…… Warren Buffet reckons forcing yourself to diversify is a mistake.
“A really wonderful business is very well protected against shocks in the economy”
It’s better to have 3 quality businesses than 100 well known big businesses. In fact, it’s less risky….
……As Buffet puts it, “Why would I buy my 27th best business when I can add more to my second or third best business”??
• Peter Lynch
“It’s a huge mistake, I’d rather own one stock”
He is clearly against diversification, he recommends buying quality businesses instead.
He argues that buying mediocre businesses to balance a portfolio is insanity, because mediocre businesses go down.
• Monkish Pabrai
“Look at entrepreneurs -They usually have everything in their business”
(all their eggs in one basket betting on themselves)
“They don’t feel like they should sell their business to buy smaller stakes in many other businesses, they are happy with single bets.
…….. Monkish Pabrai
agrees with Buffet
“If you know what you are doing, diversification makes no sense, it seems like insanity to own 20 stocks”
Monkish follows a 10 by 10 portfolio
10 stocks with 10% on each, and in his personal portfolio he has about 5 stocks only.
