Stock Alert - But Not What You Might Think
Before we cover the full analysis we make a quick alert here that Northern Trust Corporation (NASDAQ:NTRS) has seen its stock price move at an extreme low level. We'll go through the details below -- but that's the lede -- the stock has been unusally quiet.

Another bit to this alert of quiet time, which we cover in the article, is that while the historical volatility may be an extreme low level, the real question that needs to be answered for option traders is not if the HV20 is low, but rather if the implied volatility that is priced for the next 30-days accuratley reflects what we're about to see in the stock for the next month.
