EMA (Exponential Moving Average)

An EMA is a line on a price chart that shows a stock's average price over time, but gives extra weight to recent prices. Think of it like a moving average that cares more about what happened yesterday than what happened three months ago. You'll see EMAs everywhere in technical analysis—traders use them to spot trends and potential buy or sell signals. For example, if a stock's price crosses above its 50-day EMA, some traders see that as a bullish sign. The main appeal: EMAs react faster to price changes than regular moving averages, so they're useful for catching momentum early. Just remember, they're one tool among many—not a crystal ball.
