Downward trending stochastics above 72 suggest the stock is currently overbought, and the stock is threatening to break below the 10-day exponential moving average which it used as support throughout September.
Corrections Corp is currently priced close to the 10-day exponential moving average (EMA), and upward trending stochastics near 47, in addition to a relative strength index of 40, suggest the stock may be consolidating for a run higher.
So you see, what it means when a stock is trading at fair value is that you are not going to make additional money from a trending back up to fair value.
