- Mean reversion, short only
- Risk elevated
Short Bullrun is a short-side mean reversion model that fades euphoria. It looks for stocks that have risen too far and too fast into overbought territory, shorts that exhaustion and covers as the rally unwinds, usually within a few days. Short selling needs a margin account at Alpaca.

Daily return series 2 Oct 2000 to 3 Nov 2026, supplied by the provider. The provider has not marked a live start, so treat the full series as a backtest: simulated results are a hypothesis, not a promise. Past performance does not predict future returns. Your own results depend on your position sizes, fills and costs.
