A signal-driven, one-asset-at-a-time strategy that shifts between leveraged tech/bond exposure and short-term Treasuries based on SPY’s 21-day volatility, selecting the single asset with the lowest 21-day RSI among TECL, TQQQ, and TLT when volatility is low, or switching to SHY when volatility rises; weights are equal, with no automatic rebalancing.

V1b is a conditional, one-asset-at-a-time strategy. It first checks SPY’s recent volatility. If volatility is very low, it selects one asset from three high-risk/levered instruments (TECL, TQQQ) or a long-duration bond (TLT) using the lowest RSI (momentum) among them, and allocates all cash to that single asset. If volatility is moderate (<2), it uses the same selection rule. If volatility is high (>=2), it shifts to SHY (short-term Treasuries) as a safer choice. The weights are equal across the chosen asset(s) via the “wt-cash-equal” mechanism, effectively putting all the investment into the selected asset. There is no continuous rebalancing; a new signal (i.e., a new SPY volatility reading that triggers a different branch) would be required to change allocations. The “rebalance-corridor-width” of 0.05 implies a small tolerance for weight drift, but since the rebalance rule is set to none, actual rebalancing only occurs when the signal changes. Note: TECL and TQQQ are leveraged ETFs (designed to magnify daily moves of tech indices) and TLT/SHY are treasury-bond ETFs. Leveraged products can be highly volatile and are generally not suitable for long-hold strategies without proper risk controls.

Out-of-sample, this rule-based strategy targets higher upside than the S&P 500 (≈53% annualized) with solid risk-adjusted metrics (Calmar ~1.24, Sharpe ~1.34), using volatility gates. Drawdowns can be larger in downturns.
