The last few years have been great for gold investors. Since 2009, the price of gold jumped up from about $800 an ounce to a high around $1,800 last year. This is because when the economy is weak and the stock market is shaky, investors flee to gold as a safe haven. High gold prices worked out great for companies like Keegan Resources Inc. (NYSE: AKG), a small-cap gold mining firm. After nearly going bankrupt, Keegan saw its share price go up over 800 percent. This has been a great stock for investors over the past few years, but things appear to be going sour.......
