The risk in quant investing is not the model — it is the investor. Most people abandon a systematic approach precisely when it is about to work. A momentum model underperforms for a quarter, anxiety sets in, the investor exits — and misses the recovery the model was positioned for.
Momentum as a factor needs time. Stocks selected because the market is rewarding them need holding time to deliver the full return. Churning the portfolio based on short-term noise destroys the edge. The model needs to run without interference.
Use Quant Momentum. Monthly rebalancing keeps the screen current, but positions aren't replaced on short-term volatility — they're held until the framework's own exit rules trigger. The model selects, the portfolio holds, the market prices it in over time. Patience is built into the exit criteria, not the rebalancing calendar.
