Cash drag occurs when an index fund holds uninvested cash from received dividends, new investor subscriptions, or pending corporate actions. Because the index assumes full investment at all times, the fund's cash position creates a return difference. In rising markets, cash drag causes underperformance; in declining markets, it can provide a small buffer.
Factor-based indices require periodic reconstitution to update factor scores and rebalance to target weights. As stocks' factor characteristics change (e.g., a value stock becomes fairly valued, a momentum stock reverses), the index must add and remove constituents, generating higher turnover than a market-cap-weighted index, which is largely self-rebalancing (prices adjust weights automatically).
