We show that the early-stage (late-stage) momentum strategy of buying identified early-stage (late-stage) winners and selling identified early-stage (late-stage) losers outperforms (underperforms) the conventional momentum strategy of buying winners and selling losers across all momentum stages. We also find that the price momentum of the early-stage (late-stage) momentum strategy experiences slower (faster) reversal than that of the conventional momentum strategy. The outperformance of the early-stage momentum strategy comes primarily from the contribution of losers, as options-implied measures better place losers in their momentum stages than winners. Moreover, the identification ability of options-implied measures increases with the informativeness of the options market and, more importantly, is driven by their predictive information about a firm's fundamentals, particularly for profitability. Overall, our results indicate that options-implied information is useful in identifying the momentum stages of stocks. |
