Ann: Quarterly Update, page-364

First of all its worth noting that motley fool are not a great source of information. They are super biased and analysts and c*s like them put up posts like that to scare people off and drop the price and the buy in to make a profit. secondly its all about your timeframe. Generally you can ignore short term price fluctuations if you believe you're on a good thing then the share price will look after itself. I qlso wouldnt recommend putting all you money on volatile stocks if you can't control your emotions. Sometimes you need to be ready to see your holdings in the red and be willing to average down to reap the best rewards but it can be scary. If volatility is not your forte I would recommend an index fund or etf. Best of luck.
