Simple Moving Averages for Trend Signals and Breakout Trading
Summary
The document introduces moving averages as a way to smooth price data and describe trends. It distinguishes shorter and longer averaging periods, gives the arithmetic average as the basic calculation, and also describes a weighted recursive SMA convention used by Chinese trading platforms. It presents moving-average crossovers as signals: a shorter average crossing above a longer one suggests a long position, while a downward cross suggests selling or shorting.
It cautions that there is no universally best lookback period; performance varies by stock and time period. The example strategy uses a ten-day reference based on the average of the high, low, and close, buying when price breaks above it and selling when price falls below. The document supplies no backtest results, transaction-cost analysis, or detailed rules for handling whipsaws, so the strategy should be treated as an illustration rather than evidence of profitability.
Key ideas
- Moving averages smooth daily price or volume data to make trends easier to observe.
- A shorter average crossing above a longer average is presented as a bullish signal, with the reverse cross treated as bearish.
- The document says the best averaging period varies across stocks and market periods.
- Its example buys above a ten-day high-low-close average and sells below it.
- No performance evidence or execution details are provided.
