Golden Cross / Death Cross
A chart signal in which a short-term moving average crossing above a long-term one is read as a golden cross (a sign of a turn upward), and crossing below it as a death cross (a sign of a turn downward).
Golden cross = a short-term moving average (e.g., 50-day) passes from below to above a long-term one (e.g., 200-day)
A golden cross means the short-term flow has risen above the long-term flow, so it is commonly read as a sign of a turn into an uptrend.
In plain terms
There is a short-term moving average (e.g., the 50-day line) showing the price's "recent flow" and a long-term line (e.g., the 200-day line) showing the "longer flow." The moment the short line breaks up through the long line from below is called a golden cross.
Conversely, the moment the short line breaks down through the long line from above is a death cross. Think of it as a name given to the "junction where the direction of the flow changes."
What it tells you
It shows at a glance whether the recent mood (the short-term line) has moved past the larger flow so far (the long-term line). It is widely used to gauge whether a trend is about to turn up or down.
The crossing of the 50-day and 200-day lines is the most widely talked about. Because many people watch the same lines, that itself can become a signal that draws the market's attention.
Formula
Golden cross = a short-term moving average (e.g., 50-day) passes from below to above a long-term one (e.g., 200-day) Death cross = a short-term moving average passes from above to below the long-term one
What high or low means
A golden cross means the short-term flow has risen above the long-term flow, so it is commonly read as a sign of a turn into an uptrend.
A death cross is the opposite — it's read as a signal of a turn toward a downtrend. That said, both are the result of averages of "prices that have already passed" crossing, so they show up a beat late.
Moving averages are lagging indicators, so by the time a golden cross appears the price has often already risen quite a bit. The lateness of the signal is a limit of this indicator.
In a sideways market the two lines tangle often, so "false signals" — golden and death crosses appearing in turn — are frequent.
This signal looks only at price movement, so it has nothing to do with the company's value. In itself it is not a suggestion to buy or sell, but a reference tool for reading a trend.
