Relative Sector StrengthA company's performance is determined in large part by the sector it is in. (The health of the overall market is just as important.)
Charting HistoryA weekly three- or five-year chart gives you a broad historical overview of a stock or a sector. It provides an immediate snapshot of a firm's earnings history, both good and bad. Sure, you could read five years of 10-Ks and analyst reports, but why waste all that time? The picture is worth many thousands of words. You can easily see how volatile a stock is with a quick glance. A chart showing wild intraday swings and sharp reversals might raise suitability issues for more conservative investors. A more measured, gradual chart might not fit the goals of short-term, more active traders. Either way, the chart provides some insight as to whether this stock is for you.
Reality CheckHow often has a piece of fundamental data or a tidbit of "unknown" or hot information induced you to buy a stock? The chart lets you know whether that data point is baked "in the cake" already. If someone tries to convince you to buy a stock because of the hot news he has, a quick glance tells you how warm or cool the news really is. A stock up significantly over the past three months implies that the hot tip you just got ain't so hot -- lukewarm is probably more like it. As my head trader is fond of saying, "Last man in pays for the beer." Buying a stock based on an analysis that is not fresh or advantageous is a recipe for losing money. Charts have more to offer than patterns and predictions. Savvy investors learn how to use them for recognizing warning signs, managing risk and selecting stocks. Over time, you will too.
