What is the 200-week Simple Moving Average (SMA)?

The 200-week SMA is a long-term trend indicator that averages a stock's closing price over the past 200 weeks (roughly 4 years). When a stock's price falls below its 200-week SMA, it may signal a potential buying opportunity for long-term investors.
