Many investors use moving averages, and more specifically, moving average "crossovers," where one suddenly starts trading above or below the other, to try and gauge which way a market may be headed.
Among technical analysts, one combination has often been seen as a good pointer to prospective long-term trends.
The bullish version is called a "golden cross." That is when the price of a security rises above its short-term average (traditionally, the 50-day moving average), which is also above its long-term average (traditionally, the 200-day moving average).
