Questions & Answers

Q: What is a simple moving average?

A simple moving average is a technical indicator that tracks a security's price over a specific time period and plots it on a line, helping to identify the overall trend.

Q: How can an investor create a simple moving average chart?

Choose a time frame (e.g., 20 days), calculate the average price for each day within that period, and plot the results on a chart. Continuously update the moving average by dropping the oldest price and adding the latest price.

Q: How can moving averages help investors decide when to buy or sell a stock?

Moving averages can act as support or resistance levels. When the price breaks above an upwardly sloping moving average, it may be a good time to buy. Conversely, a bounce off the moving average could signal a sell opportunity.

Q: What are the drawbacks of using simple moving averages?

The main drawback is lag, as simple moving averages are slow to reflect price changes. Additionally, they can generate false signals called whipsaws, where the stock initially gives one signal but then quickly reverses.
