cash clay, 1) i'm almost positive that is bad data on the chart 2) carl icahn didn't "invest" in SSE, he got it as part of the spinoff of Chesapeake. There is 1.5bn of debt on the company (a nice chunk due in 2019) and for icahn this little spin off is like 0.0001% of his portfolio. And, its pretty much worthless for him.
This play is highly levered to the price of oil, there is currently almost no equity value to the company at present (a lottery ticket) as the market knows that the company is so underwater on its debt its hard to imagine it being repaid if oil were to stay in this range for an extended period.
But if you're up for trading a stock that has little liquidity and barely any equity value, go for it.
