According to @KobeissiLetter, the Russell 2000 has outperformed the S&P 500 for 10 consecutive sessions, the longest run since 1990, with small caps up 7.5% over the period versus 1.3% for large caps (source: @KobeissiLetter). This indicates a multi-decade-extreme phase of small-cap relative momentum that traders can express via long IWM versus short SPY or by overweighting small-cap exposure, while managing mean-reversion risk after a 10-day streak (source: @KobeissiLetter). For crypto-focused desks, the source documents an equity risk-on episode in small caps but provides no direct crypto data; any BTC or altcoin correlation assessment should be derived from internal models rather than assumed (source: @KobeissiLetter).

According to @EricBalchunas, he wagered on ETF IQ that U.S. small caps will lag large caps through year-end 2025, signaling a bearish small-cap versus large-cap relative view.
