Based on an analysis of quarterly sector performance during the period 1995-2006, S&P 500 economic sectors that perform best in any given quarter tend to fare less well in the three months that follow. In contrast, groups that perform worst tend to improve their relative standing in the subsequent span.

So far this period, utilities and materials have been the best performers by a relatively wide margin. The laggards have been financials and consumer discretionary shares. If past trends hold true, it might make sense to shift sector allocations for the next three months away from shares in the winning sectors towards those in groups that finished at the bottom of the pack.

It's worth noting that this is a relative performance strategy. Some or all of the ten sectors could finish higher or lower next quarter, depending on what happens to the overall market.
