We document option momentum spillovers across peer firms with shared analyst coverage. Firms whose peers have higher past-12-month delta-hedged straddle returns tend to have higher future option returns. Peer option momentum has a magnitude similar to the option momentum documented by Heston et al. (2023), but it is distinct from option momentum. Past option returns of a firm’s peers can predict the firm’s realized variance even after we control the firm’s option-implied variance and its own past option returns. In addition, peer momentum is stronger for indirect linkages. The findings are consistent with limited investor attention on volatility information from peer firms. Compared with peer stock momentum, peer option momentum persists longer and exhibits spillovers via more economic linkages that cannot be subsumed by analyst-based linkages.
