A daily rebalanced, high‑risk overlay that toggles between SOXL (semiconductors), SPXS (S&P 500 inverse), UVXY (volatility), and BIL (cash) based on short-term RSI and volatility signals to seek upside in semiconductors while hedging during volatility.

What you’re seeing is a rule-based overlay that sits on top of a small set of ETFs. Assets used: SOXL (3x bet on semiconductors), SPXS (3x bet against the S&P 500), UVXY (volatility proxy; goes up when volatility rises), and BIL (short-term Treasuries for safety). Signal logic at heart: - Momentum signals (RSI) on UVXY and SOXL tell the system when those assets have had recent strength or weakness. - Very short-term volatility check (2-day累積 return on UVXY) helps decide if volatility is spiking and risk needs to be reduced. - If signals look favorable for growth (SOXL momentum positive and volatility moderate), the system tilts toward SOXL; if signals warn of risk (volatility rising or momentum weakening), it shifts toward SPXS or UVXY and/or BIL to dampen risk. There are several named “wraps” (scenarios) such as Gobi’s Vol Catcher Wraps and Vol Catcher Only, each with its own allocation rules. The allocations are updated daily, so the position can swing between growth (SOXL), hedges (SPXS/UVXY), and cash-like buffers (BIL). Why this could work: it attempts to ride uptrends in the semiconductor space when momentum is favorable while guarding against volatility spikes with hedges and safe cash. Why it could fail: leveraged ETFs can magnify losses quickly, and timing signals can misfire during fast-moving markets. The strategy assumes a willingness to take on high risk for potentially higher short-term returns and accepts drawdowns in adverse periods.

Out-of-sample, this high-risk overlay captures semiconductor upside with strong risk controls: annualized return ~91% vs S&P ~50%, max drawdown ~1% vs ~6%. It dynamically tilts among SOXL, SPXS, UVXY, and cash to ride trends and hedge volatility.
