Dr. Andrew Lo: ‘Buy and Hold’ Does Not Work Anymore

Dr. Andrew Lo is a thought leader in the world of portfolio management.

The MIT/Sloan School of Management professor and Director of MIT’s Laboratory for Financial Engineering has been widely quoted on the implications of the 2008 financial crisis. One theme that Dr. Lo emphasizes repeatedly is that the risks associated with different asset classes can vary dramatically over time and for this reason, risk must be tracked, forecasted and budgeted.

In a world in which the risk of any given asset class (and therefore, also the risk of any portfolio of asset classes) can change dramatically in a short period of time, a passive buy-and-hold approach may, in fact, result in unacceptable levels of volatility. Continue reading

Burton Malkiel Says Buy and Hold is Alive and Well, and it Works

Burton G. Malkiel, the Princeton professor who brought Efficient Market Theory to the mass market in his classic A Random Walk Down Wall Street has taken up the defense of buy and hold investing, and the idea of diversification more broadly.

Ever since the trauma of 2008 when so many global asset classes moved down in tandem,  there’s been ample discussion of the merits of diversified portfolio building. Many assets classes have continued to be highly correlated.

Arguing about the Market’s Best Days

In the Big Picture post on this chart earlier this week,  Barry Ritholtz is drawn to that spiking yellow line.  “If you manage to avoid the 10 Worst Days, your portfolio  more than doubles the Buy & Hold performance,” he writes. $100,000 invested in the S&P 500 ETF  in February 1993, would have grown to a total of $692,693.00. Buy and hold gets you to $324,330.15.

Figure out a way to miss the losing periods, Ritholtz notes, and you’re literally golden.

But to me, it’s just as interesting that the 10 best days almost exactly outweigh the 10 worst days. Continue reading
