There is no single magic signal that will tell you when to buy a stock or index.
However, the golden cross has proven to be one of the more reliable, although not infallible indicators.
The pattern is formed when a shorter-term moving average, most commonly the 50-day moving average, crosses above the longer term 200-day moving average. The trend, coupled with strong trading volume is seen as a key indicator of bullishness left ahead and can help mindful investors ride a continued upward trend.
Additionally, with algorithmic trading becoming an ever more dominant trend, the technical factor can spark added buying pressure and cement that trend.
For a concrete example, the S&P Homebuilders index (XHB - Get Report) formed a golden cross pattern after rosy reports from KB Home (KBH - Get Report) and Lennar Corporation (LEN - Get Report) in late March. After crossing that line, the index ran nearly 10% to the upside in just the next week. Not a bad time for chart-watching traders.
