Short Position in Leveraged Inverse ETF Options in light of a potential market correction

During recent trading sessions, the major indices have shown signs of exhaustion at higher levels, with a decline in institutional buying momentum and a rise in short-term implied volatility. The structure of the The S&P 500 and the Nasdaq 100 This reflects a phase of contained distribution, with accumulated technical divergences and an increase in the volume of puts purchased at 7, 60, and 776 DTE. In this context, I am conducting a Tactical entry using call options on the leveraged inverse ETF SPXS.

Long Call on SPXS: Structure and Trading Rationale

The position is one Long Call Strategy which directly exposes us to an increase in the value of the leveraged short index on the SPX:

ContractCall 40 · Maturity: January 16, 2026

Time Horizon76 DTE since the position was opened
Adjusted deltaElasticity >0.40 compared to the underlying asset

Potential upsideOpen amid sharp declines in the SPX

The choice of a Call 40 With ~76 days to maturity, it allows investors to capture a potential corrective move in the S&P 500 without incurring the daily erosion typical of leveraged ETFs, thereby benefiting from a delta-adjusted elasticity greater than 0.40, which amplifies the premium's positive sensitivity to increases in implied volatility and declines in the index.

Unlike direct short positions in futures or short positions in stocks, a call option on SPXS has a a fixed risk from the start: The maximum loss is always the premium paid. If the S&P 500 continues to rise, the position simply expires worthless. If the anticipated correction occurs, the convexity of the leveraged ETF (×3), combined with the leverage of the option, generates an asymmetric return far greater than that of a direct position.

Macroeconomic Context

Why Go Short Now: Structural Weakness on Three Fronts

The rationale behind this position is not tactical, but rather structural: a set of converging signals pointing to a gradual deterioration in credit conditions and a loss of momentum in the factors that had sustained the final leg of the rally.

Goldman Sachs: Hedge Funds Balancing Long and Systematic Short Positions in Indices

According to the latest report from Goldman Sachs Prime Brokerage, hedge funds were net buyers of global stocks for the second consecutive month (+0.4σ), driven by sustained buying of individual stocks. However, the most significant figure is in the macro positioning:

SegmentFlowLevelContext
Individual ActionsNet purchase6th consecutive month · +0.7σLong/Short Ratio: 3 to 1 · Technology, Industrials, Materials
Macro Products (Indices and ETFs)Net sales4th consecutive month · –0.3σShort positions 1.3 to 1 compared to long positions

% Short Positions in ETFs on Total13,301 TP3T of the total short positions96th percentile for the past year

This institutional repositioning indicates that the funds have begun to hedge long exposures with systematic index sales., a strategy that typically precedes periods of correction in the equity market when credit conditions deteriorate. The concentration of short positions in ETFs in the 96th percentile for the past year confirms the scale of the defensive shift.

Synthesis

A defensive stance in the face of structural deterioration

Short-selling is not justified as a speculative tactical move, but rather as a defensive position in the face of structural deterioration which converges to three simultaneous vectors:

Vector 01 · Credit

The Fed maintains a restrictive bias which is putting pressure on multiples. The market for commercial real estate loan It acts as a source of systemic risk, with CMBX spreads widening and delinquency rates exceeding the critical threshold of 10%. Commercial banks with record exposure to CRE are vulnerable to any contagion from the sector.

Vector 02 · Institutional Momentum

Hedge funds are systematically selling indices and ETFs while maintaining long positions in individual securities: the classic strategy of reducing beta exposure in environments of deteriorating credit conditions. The VIX above 22 indicates early signs of stress.

Vector 03 · Assessment

The Long positions lose their asymmetry as interest rate cuts cease to be an immediate catalyst. The economy is beginning to reflect the consequences of two years of restrictive monetary policy. Hedging becomes the most rational approach to risk management in this context.

Estimating the Impact on a Long Call on SPXS in the Event of S&P 500 Corrections

Enter the current price of SPXS, the estimated percentage decline in the SPX, and the call option parameters. The tool estimates the new price of SPXS (assuming a multiplier of ×3) and the potential return on the premium.

SPXS price at the time the position was opened.
The SPX falls by this % → The SPXS rises by ~3× that percentage (intraday).

Estimated SPXS Variation+15,0%
Total admission cost$215
Estimated post-correction premium~$5,40
Estimated P&L+$325
Return on Premium+151%
Note: The impact on SPXS assumes a nominal ×3 multiplier on the SPX’s daily movement. During prolonged movements lasting several days, the ‘volatility drag’ of the leveraged ETF may differ from the theoretical multiplier. The post-correction premium value is a simplified linear approximation based on delta; in practice, an increase in implied volatility (vega) also increases the premium, favoring the position. This does not constitute financial advice.

Frequently Asked Questions

Questions About the Position and About Diego García del Río

What is SPXS, and how does it work as a hedging tool?

SPXS (Direxion Daily S&P 500 Bear 3X Shares) is a leveraged inverse ETF that seeks to track three times the inverse daily movement of the S&P 500. If the S&P 500 falls by 1% in a single day, SPXS rises by approximately 3%. Buying out-of-the-money (OTM) calls on SPXS allows investors to capture potential market corrections with risk limited to the premium paid.

Why use a call option instead of buying SPXS directly?

The call option offers superior convexity: risk is limited to the premium paid, while the upside is amplified if the corrective move is significant and rapid. Furthermore, as an option with 76 DTE, it avoids the daily erosion of the leveraged ETF’s value in sideways or moderately bullish markets.

What macroeconomic indicators justify this short position?

Several indicators point in the same direction: (1) delinquency rates on office CMBS are at a record high of 11.80%, surpassing the peak of the Great Financial Crisis; (2) Powell is hawkish, and a December rate cut is far from a certainty; (3) hedge funds are increasing their short positions in macro products to the 96th percentile of the past year, according to Goldman Sachs; and (4) the VIX is above 22.

How is the impact of a decline in the SPX on the SPXS calculated?

Since SPXS tracks the daily movement of the SPX with a 3x inverse ratio, when the SPX falls by X%, SPXS rises by approximately 3X% on that day. For prolonged movements lasting several days, the effect of daily rebalancing introduces some lag, but in rapid, straight-line declines, the amplification is close to the nominal 3x multiplier.
