Momentum plays bet that what has risen most over the past months tends to keep outperforming for a while. The family guide
How to use it
- It trades often (about 12 switches a year per stock), so costs, spreads and taxes eat into it more than the backtest's 0.05% per switch suggests.
- Expect to be wrong more often than right: only 38% of its calls worked. Its results come from the size of the winners, so following it means sitting through strings of small losses.
- It worked best on Micro caps (50% beat holding on risk-adjusted return) and worst on Media & telecom (0%).
- Use it as one input. Your signal combines the plays you count with the other factors you weight into one call.
