Daily up/down rotation between SPY and TLT to beat SPY by using bonds when risk rises; stay in SPY on positive trend and calm market signals, switch to longs bonds if volatility climbs or trend weakens.

- Assets used: SPY (US stocks) and TLT (long-term US Treasuries). - Core idea: Be mostly in stocks when the market looks healthy, but shift into bonds when stock signals weaken or volatility rises. - How it decides to stay in SPY: If SPY’s longer-term trend is positive (100-day simple moving average above SPY’s 150-day exponential moving average) and short-term price signals aren’t tipping the balance the other way, it aims to allocate fully to SPY (100% stock exposure). - How it decides to move toward bonds: If the market signals weaken (e.g., SPY price relative to a 5-day average suggests weakness, or SPY’s 10-day volatility exceeds a threshold around 3%), the rule shifts exposure toward TLT (bond exposure). - Rebalancing: Daily. The two-weight logic with SPY and TLT means the portfolio wavily tilts between the two assets based on the conditions. - What this means for you: If markets look calm and uptrending, you largely own stocks. If markets get choppier or trend signals weaken, you tilt toward bonds to dampen risk. - Important caveat for lay readers: This is a mechanical, backtested-looking rule set and does not guarantee outperformance. Real-world results depend on execution, transaction costs, and market regime changes. In short: The strategy tries to keep you in stocks when things look good and move you into bonds when risk appears higher, with daily checks on trend and recent volatility to guide the decision.

Dynamic SPY/TLT rotation keeps you invested in stocks when uptrends hold and shifts to bonds in riskier markets. Out-of-sample: Sharpe ~0.69, Calmar ~0.61, and drawdowns similar to SPY, delivering disciplined, diversified growth.
