And over the latter half (1958-2015), returns were no better at all."..."But there is a simpler form of market timing, which has some empirical support: rebalancing. It requires investors to decide first how they want to divide their investments. It could be, say, an equal split between American and non-American stocks. The precise weights matter less than that they are stuck to. That requires regular rebalancing to restore the original weights. It means shedding assets that have risen a lot in favour of those that have gone up by less.The virtue of rebalancing is that it is simple. You are less likely to make a costly mistake than if you follow a more complex strategy."
