In particular, consider the following three investments.
CCJ: Cameco Corporation - Prior to the meltdown in mid-March, this stock was trading at right around $38 per share. There was a sudden, severe drop off, and the stock now trades close to $28. Have the fundamentals of the company changed in that time period? Certainly not, but the market appears to be sketched out concerning nuclear power, and this uranium producer feels the sudden pinch.
URA: Global X Uranium ETF - This exchange traded fund had the misfortune to be founded in mid-January, so it had a couple months at an average price around $21 before falling and now hovering just under $15. If you think that Cameco has the opportunity to grow, this fund helps to take away some of your risk while providing you exposure to an industry that could stand to make quick growth (21.76% of the fund is invested in Cameco stocks).
EXC: Exelon Corporation - If investing directly in a company that focuses exclusively on uranium production seems too focused, this utility that derives a good portion of its power from nuclear plants might be a good option. This stock is approximately 10 % off the price it held prior to the radiation leaks at Fukushima Daiichi, and if uranium prices have gone down as a response to the disaster, it stands to profit. Its current price to earnings (P/E) ratio is a very attractive 10.5, and the future P/E is also quite attractive at 13.37.
Disclaimer: I am not a financial professional by any stretch of the imagination. I also do not own any of these stocks, though I may make an investment within the next 72 hours.
