The huge swings are more than just shorts or technical reasons. I sense it might be partly due to the idea that stocks might be in for a rough year and money pulled out of the stock market might be diversified into other forms of investing. If traders begin dumping their stocks and moving out of the stock market; they might begin to buy gold and silver, but other forms of investing, such as real estate or collectibles such as baseball cards or coins might also see an uptick. A down stock market and 0% interest in the bank leads people to wonder what to do with their money.
huge short position that went in Oct/Nov 2012 at around $12. They have realized they made a huge mistake and the company will grow into their dividend. Plus the company has now put up good number 4 straight quarters with good revenue, good profits, and fantastic international growth.
International revenue has gone from almost zero to now 8%. China is still growing and I wouldn't be surprised if international revenue is 12%-15% by year end.
So now you have short covering, long buying, hedge fund interest, a solid dividend, and a very low float. Charts and normal analysis can be thrown out the window.
