Less Risk, More Return .The curious tale of less-liquid stocks. -- Rather, they were created by ranking all stocks by their liquidity, from a 2014 Journal of Portfolio Management article entitled "Dimensions of Popularity," by Roger Ibbotson and Tom Idzorek. (Liquidity, meaning the ability to trade the security, is calculated in this instance as the percentage of a stock’s shares that are traded each day. The higher that percentage, the higher the stock’s liquidity score.) The top-gaining quartile, that is the group that averaged 15.5% per year, consisted of those stocks that had the lowest liquidity. Conversely, the bottom quartile, which lagged far behind at 8.27%, held the most-tradeable stocks. -- I would say that egrx is among the low liquid hence the jerky moves at times. http://news.morningstar.com/articlenet/article.aspx?id=733808
