In technical analysis, traders look for patterns in stock prices, which they then use to determine buy/sell decisions. One such pattern is the "head and shoulders," which, as the name suggests, is two small peaks, with a larger one in the middle. Such a pattern is often considered bearish, particularly if the price breaks through the "neckline." Unfortunately (or not, depending on your view of technical analysis), Apple's share price recently exhibited this pattern. See the article here, Yahoo.
