Modelling UVXY Short Strategies and Tracking Error in Leveraged Volatility ETFs
Summary
The document explains how UVXY’s daily leverage target and maturity maintenance lead to recurring portfolio rebalancing, and uses spreadsheet models to examine two trades: shorting UVXY with periodic rebalancing, and shorting a basket of UVXY and an inverse volatility ETF to isolate tracking error. Historical price behavior illustrates UVXY’s persistent decay alongside sharp upside bursts. The short strategy can profit over time but suffered severe losses during volatility shocks; more frequent rebalancing limits exposure drift while increasing trading costs.
The basket strategy aims for volatility neutrality so returns reflect deviations from each fund’s target exposure. The author reports that it appeared more attractive before the ETFs reduced leverage after Volmageddon, then largely ceased working as tracking improved. These results are presented qualitatively through spreadsheet charts rather than detailed performance statistics. Trading and borrow costs are omitted, and the document warns that they could materially reduce returns, particularly for the tracking error trade. Position sizing and rebalance frequency remain important risks.
Key ideas
- UVXY’s daily leverage and maturity targets require ongoing rebalancing.
- A short UVXY position may benefit from decay but can incur large losses during volatility spikes.
- More frequent rebalancing controls position drift while increasing trading costs.
- A volatility-neutral UVXY and inverse ETF basket seeks returns from tracking deviations.
- The analysis omits trading and borrow costs and describes the basket strategy as less attractive after leverage changes.
