moving average
A technical indicator that smooths price data by creating a constantly updated average price over a specific time period, helping identify trends.
Example
“Traders watch when the 50-day moving average crosses above the 200-day as a bullish signal.”
Memory Tip
MOVING average = the average MOVES with time. Smooths out the noise in price charts.
Why It Matters
Moving averages help traders and investors identify price trends without getting distracted by daily price fluctuations. Understanding this tool can improve your ability to make better timing decisions when buying or selling investments, potentially protecting you from making emotional decisions based on temporary price swings.
Common Misconception
Many people believe that a moving average predicts future prices or guarantees profits, but it actually only shows past price behavior. A moving average is a tool for understanding current trends, not a crystal ball that tells you where prices will go next.
In Practice
If you track a stock that closed at 100, 102, 98, 101, and 103 dollars over five days, the 5-day moving average would be 100.80 dollars. On the next day when the stock closes at 105, you would drop the first price and add the new one, giving you a new average of 101.80, helping you see that the trend is gradually moving upward.
Etymology
MOVING (constantly updated) AVERAGE (mean of past prices). The average MOVES forward in time.
