Share Turnover and Stock Returns

Using share turnover as a measure of stock popularity started to gain a lot of attention when Roger G. Ibbotson and Thomas M. Idzorek published their paper Dimensions of Popularity in the Journal of Portfolio Management at the end of 2014. Based on their research, the authors proposed the most popular stocks underperform in the long run. On average, the best returns are received from companies with low share turnover.

Based on this paper, the Economist magazine proposed that the popular shares will often become victims of the momentum effect: the temporal popularity drives up the price on short term (matter of months). But the long term earnings rarely meet the unreasonable expectations loaded on the company and the price will soon start to plunge.

Many speculative investors jump in when the bubble is about to reach its peak and normally generate the biggest losses for themselves. It is wise the very of companies too often in the news, firms with extremely hot product or stocks that are recommended by too many analyst.
