Strategy #0000000111 · Factors and time-series momentum

Factor momentum
Enter trailing and next-period returns for three factors plus costs to inspect normalised long-short weights.

Factor momentum uses each factor’s own recent return to set its holding direction: recent winners remain long and losers short. It differs from stock momentum; factor correlation, lookback, rebalancing and costs matter. Research finds factor time-series persistence can explain part of stock momentum, without guaranteeing future continuation.

How do trailing factor directions form long-short weights?
