FYI: During the past 40 years, low-cost indexing has risen from an abstract financial theory with very few takers to a juggernaut sucking up most of the new money flowing into equity investments. BlackRock Inc., Vanguard Group Inc. and State Street Corp., 1 the top three indexers, collectively own more than 10 percent of every company in the U.S. They own lots of overseas stakes as well.
