I'm not much of a chart guy when analyzing companies, but Oceaneering may have one of the poorest charts I've seen over the last 7 years. I'd be very, very curious what your banks logic is on purchasing the company.
Contago has negative book value per share, a current ratio nearing 0.5 (showing negative working capital) and only around $400,000 in cash when they have nearly $90 million in debt.
Petroshale I don't even feel comfortable commenting on, strictly because of liquidity issues. The stock has average volume of 124,173 and a share price of $0.13. This is only $16,142.49 in transactions a day. To me, that's a liquidity nightmare. You would more than likely have difficulty moving even.... $2000 worth of shares.
Suncor I hold, but am looking to get rid of it when it recovers a bit. I see some upside in it right now, but don't plan to hold long term.
And in terms of FEN, I've never really looked at a mutual fund my whole investing career. I'm not an expert in the funds.
In terms of whether or not you should sell, I'm not sure to be honest. I know nothing about your positions. I'm not sure if you got in at the highs, the lows etc. I'm not sure on your overall outlook on the oil and gas industry.
Buying/selling is really dependent on an individuals situation. The one thing I can say though, is think of the reason you bought them. Has that reason changed? This is often a catalyst for me to sell.
