Stock price when the opinion was issued
Chart shows a channel formation in 2012 and 2013, followed by a severe drop in the last half of 2014. This is not a good sign. Feels that the sudden drop has taken the stock so far from the mean that it should rebound. If crude continues lower, there is no bottom in sight for the stock. If you are trading, and it makes a 52-week low, he would sell immediately.
This stock was very unattractive before the oil slide. At oil prices now, balance sheet gets weaker and the cash flow is about 3.9X. Valuation gets pricier, not horrible at 8.3X versus its peers at around 7.5. Dividend is not safe. Prefers others.
