Here's an investing strategy for emerging markets that claims it will generate 75% of a 'fully invested' strategy, but with half the volatility.

Emerging markets investors worried about a pullback can do what Bob Phillips, a managing partner at Spectrum Management Group in Indianapolis, calls "creating an anchor."

Every month the allocation should be rebalanced back to a 50-50 split. Over time, Phillips says, that strategy has produced 75% of the returns with half the volatility.
