Remember my exhortation against stock picking, due to the few winners driving gains and the majority of stocks being meh or losers? This Morningstar article posted an insightful finding based on a recent study:
Half of U.S. stock-market wealth creation has come from 0.33% of listed companies.Please note, that figure is not 33%. It is one third of 1%—one security out of 300.Of the 26,000 stocks that appear in CRSP’s database, 86 provided half the aggregate wealth creation, 282 are required to reach the 75% figure, and 983 account for the full 100%. That is, after the 983 highest wealth creators, the remaining 25,000-plus securities are net neutral. Some made money for their investors, and some lost, but overall they were a wash.
In other words, do as your columnist prescribes, not as he does: Diversify. Widely and broadly.
