Along with fixed share funds, the rise of Target Date Funds (TDFs) has moved a significant share of retail investors into contrarian trading strategies that rebalance between stocks and bonds so as to maintain age-appropriate portfolio shares. We show that i) TDFs actively rebalance within a few months following differential asset-class returns to maintain stable portfolio shares, ii), this rebalancing drives contrarian rebalancing flows across funds held by TDFs, iii) investors do not move funds into or out of TDFs to offset these flows, and iv) using fund holdings to measure (indirect) TDF ownership, these flows have quantitatively large effects on stock prices. Continued growth in TDFs may dampen stock market volatility and increase the transmission of shocks between asset classes.
