What is MACD?

MACD (Moving Average Convergence Divergence) tracks the momentum of a stock — whether buying pressure is building or fading — by comparing two moving averages of the price.

The idea in one paragraph

Take a fast moving average (12 days) and a slow one (26 days). When the fast one pulls away above the slow one, recent buying is stronger than the longer trend — momentum is building. When it sinks below, recent selling dominates. MACD is simply the gap between the two, plotted over time.

What to look for

Example: A stock is still above its 50-day average, still in an uptrend — but MACD has just turned negative. Price says "fine"; momentum says "slowing". Often the price follows the momentum within weeks. That disagreement is exactly the early warning MACD exists to give.

The honest limitation

MACD is built from moving averages, so it lags. It will never catch the exact top or bottom — it confirms turns after they begin. Used as momentum confirmation alongside trend and support levels, it's one of the most useful indicators there is. Used as a standalone signal generator, it whipsaws in sideways markets.
