營收創新高動能策略

The Highest Monthly Sales Momentum Strategy

摘要


本研究使用單月營收對最高單月營收比率構建營收創新高動能策略,其可獲取1至12個月顯著正的平均報酬。營收創新高動能是一個獨特的效應,在控制價格動能、52週高價動能、盈餘動能、營收動能、投資者關注與風險等因素之下,仍然持續存在。本研究也發現投資者傾向對接近歷史最高營收之好消息過度反應,以及對遠離歷史最高營收之壞消息反應不足,以致營收創新高動能長期不存在價格反轉。

並列摘要


In this study, the ratios of monthly sales to the highest monthly sales of listed companies in Taiwan are used to construct the highest monthly sales momentum strategy, which generates significant positive average returns over 1- to 12-month holding periods. The highest monthly sales momentum is a unique effect that persists even after controlling price momentum, 52-week high price momentum, earnings momentum, sales momentum, investor attention, and risk. I also find that investors tend to overreact to good news near the highest sales and underreact to bad news far from the highest sales, so that there is no long-term price reversal in the highest monthly sales momentum.
