NEW YORK ( TheStreet) -- For many Apple investors, the stock is only a couple of down days before it's time to wash their hands of it. It's easy to understand, when the news is full of reasons why you should sell and the shares are trading near 52-week lows.Typically, when a stock is trading near 52-week lows, it's a sell. After all, there's a reason why investors are bailing out, and the market usually gets it right. But sometimes the market is wrong, and it isn't changes in the fundamental business model that's driving share price; it's emotion and fear. You're making a substantial mistake if you underestimate the role emotion play in pricing securities. Emotion is especially influential during relatively short time periods. We see it every day in the market. A stock can gap higher at the open, fall below the previous day's low, and then spring back to close at a new high. Obviously the underlying company didn't change in value in a single day. In all likelihood, the company produced about the same amount of widgets as it made the day before and will make the next day. The force moving the share price is emotion, and while it's easy to visualize its impact during a single day, investors should know that the same applies over the course of days and weeks. RSH) and Pitney Bowes ( PBI), Both have falling revenue and earnings. The monthly charts take away most of the noise and leave you with a true sense of direction. Now try the same with Apple ( AAPL). Apple's monthly chart has rising 60-, 90-, and 200-period moving averages. With a price near $400, the stock is also trading well above the moving average. What this tells me is that money continues to flow into Apple, but emotion during 2012 drove it too far too fast. In other words, once you remove most of the emotional drivers and ignore everything other than the core (sorry, bad pun), what you're left with is a rising stock with solid fundamentals.
