Can Index Returns be Enhanced Without Using Forecasts?

Enhanced indexing is suddenly a hot topic. The authors conjecture that much of this interest is driven by dissatisfaction, for the past several years, with active large capitalization US equity returns. But if poor large cap equity returns are the result of poor forecasts, why should one have any more confidence in an enhanced indexer’s ability to forecast? Producing enhanced index returns without forecasts are a possible solution to this dilemma. Are there methodologies to produce enhanced returns that do not require forecasts?
