As the festive season approaches investors will be preparing for the boring but essential job of selling some of their wonderfully-performing US shares to rebalance their portfolios back into underperforming bonds, protecting some of those gains.

The question investors face is whether such diversification will help protect their portfolios in the future.

Former US Treasury Secretary Larry Summers warned of the dangers in the eurozone in his latest op-ed for the FT, and it is hard to disagree. But part of what he said bothered me:

A worrisome indicator in much of Europe is the tendency of stock and bond prices to move together. In healthy countries, when sentiment improves stock prices rise and bond prices fall, as risk premiums decline and interest rates rise. In unhealthy economies, as in much of Europe today, bonds are seen as risk assets, so they move just like stocks in response to changes in sentiment.
