Long ETC / Short SPX · 1h pair

Pair is strongly reverting towards the mean with accelerating velocity and stable volatility. Regime: STRONG_REVERSION (high confidence) Correlation: 0.67 · Cointegrated: yes Z-score: -2.88 entry / -2.97 rolling Half-life 138.3h · Hurst 0.90 · Hedge ratio 0.69 Pair volatility: 46.13% Backtest: 71.43% win · Sharpe -1.05 · -0.48% return · 1.37% max drawdown The recent divergence between Ethereum Classic (ETC) and the S&P 500 Index (SPX) on the 1-hour timeframe appears to be driven by distinct fundamental and market dynamics affecting each asset, which have caused their prices to move counter to their usual correlated behavior. ETC’s relative strength amid a broader equity pullback suggests a sector-specific or crypto-specific catalyst, while SPX’s weakness likely reflects broader macroeconomic or risk-off sentiment impacting equities. From the narrative side, recent data points to a resurgence of interest in ETC, possibly fueled by renewed developer activity or network upgrades that have caught investor attention, driving ETC prices higher despite the general risk aversion seen in traditional markets. Meanwhile, SPX has been under pressure due to lingering concerns over inflation data and cautious corporate earnings outlooks, which have dampened investor appetite for equities. This divergence is further accentuated by the crypto market’s growing decoupling from traditional assets in certain regimes, where digital assets like ETC can rally on idiosyncratic news even as equities falter. Quantitatively, the signal is compelling for a mean reversion. The pair’s cointegration confirms a stable long-term equilibrium relationship despite short-term deviations, making the current spread anomaly statistically significant. The rolling and static z-scores being deeply negative indicate that ETC is undervalued relative to SPX at this moment, reinforcing the likelihood of a corrective move back toward the mean. The high Hurst exponent close to 0.9 suggests strong persistence in the spread’s behavior, implying that the current deviation is not random noise but a meaningful divergence likely to revert. The half-life of roughly 138 hours indicates a moderate speed of mean reversion, giving enough time for the spread to normalize without being too slow to capitalize on. The regime classification as STRONG_REVERSION with high confidence, supported by accelerating velocity toward the mean and stable volatility, further strengthens the case that this divergence is not a breakdown of the relationship but a temporary dislocation. Backtest results, while showing a modest overall return, demonstrate a solid win rate above 70%, indicating that trades triggered by similar signals have historically been profitable more often than not. The negative total return and Sharpe ratio suggest some risk and drawdowns, but these are within acceptable limits given the strategy’s nature and the current regime’s strong reversion signal. In summary, the divergence is plausibly caused by ETC-specific positive developments contrasting with SPX’s macro-driven weakness. The quantitative metrics confirm that this spread deviation is statistically significant, persistent, and occurring in a regime conducive to mean reversion. This combination of fundamental narrative and robust quantitative evidence makes the case for expecting a reversion back toward the historical equilibrium between ETC and SPX quite probable.
