Uses QQQ’s short‑term “hot/cold” reading to flip daily between a bearish hedge (VXX) when too hot, an aggressive bull bet (TQQQ) when too cold, or a safer asset (XLP or VBF) in between.

Each day, it checks a 0–100 “heat gauge” of recent moves on QQQ (the tech‑heavy Nasdaq‑100). If that reading is very hot (>79), it buys VXX, which tends to rise when stocks fall. If very cold (≤28), it buys TQQQ, a triple‑speed bet on a rebound. Otherwise, it parks in the more beaten‑down of two safer choices: consumer‑staples stocks (XLP) or an investment‑grade bond fund (VBF).

Rule-based strategy using QQQ heat to time VXX hedges, leveraged rebounds (TQQQ), or defensive assets (XLP/VBF). Out-of-sample Calmar ~0.67 with solid risk-adjusted performance offers diversification and added resilience vs the S&P 500.
