This MarketWatch article notes that 22% ($1.7 trillion) of mutual fund assets are now in passively managed index funds, double the amount from ten years ago.
Not so fast...Might this marked shift towards passive management have made the market more easily beaten? That's an intriguing question, since the markets' much-vaunted efficiency comes from so many investors trying to do better than simply buying and holding. That means, ironically, that in a world in which everyone is invested in an index fund, the market would be quite easy to beat.
...investment managers who are trying to beat the market trade much more frequently today than they did a decade ago.
The bottom line remains unchanged:So, even though active fund managers have a smaller market share than a decade ago, on average they today are more aggressive in their active management. These two trends largely cancel out, leaving little net effect on market efficiency...
My three decades of tracking investment advisers has shown that, over long periods of time, about one out of five advisers are able to do better than simply buying and holding an index fund. While that means it isn't impossible to outperform the market over the long term, the odds are stacked against us.
