BioMarin Pharmaceutical Inc (NASDAQ:BMRN) Stock Volatility Hits A Tumbling LowDate Published: 2017-11-25
Stock Alert - But Not What You Might Think
Before we cover the full analysis we make a quick alert here that BioMarin Pharmaceutical Inc (NASDAQ:BMRN) has seen its stock price move at a tumbling 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 a tumbling 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.

BMRN Recent Stock Volatility
Stock volatility using proprietary measures has hit a tumbling low level.
Even though BioMarin Pharmaceutical Inc generates substantial revenue, its market cap is small enough that just the fact that it's a biotechnology pharmaceutical company, in and of itself, makes BMRN susceptible to excessive risk as the stock may vascillate based on drug trial results, FDA decisions, competitor FDA data, new government pricing rules, and especially takeover rumors.
We also note that BMRN has negative GAAP earnings in the last year which makes it ever more susceptible to stock volatility.
