March 20, 2026 (Friday): Index ETFs Turn Sharply Bearish While Tech Giants Maintain Bullish Support

Hong Kong SAR – The US stock options market on March 20, 2026 revealed a striking divergence in sentiment. The total net Dollar-Weighted Open Interest (DWOI) turned negative at -1.51M, driven by massive bearish positioning in index ETFs. Of the 27 tracked securities, 15 remained bullish while 12 turned bearish.

Key Findings

Index ETFs Signal Institutional Hedging

All major index ETFs showed strong bearish signals, indicating institutional-scale hedging activity:

SPY's net DWOI reached -2.67M with a daily change of -929K, signaling large-scale put protection building by institutional investors. IWM (small-cap index) showed equally alarming bearish positioning at -1.85M, suggesting a sharp decline in risk appetite for smaller companies.

VIX Bullish — Volatility Expectations Continue Rising

VIX led the bullish rankings with +1.86M net DWOI and was one of the only securities with positive daily DWOI change at +279K. This confirms traders expect further market turbulence ahead, aligning with the bearish index ETF signals.

Tech Giants Still Bullish but Momentum Fading

While NVDA, GOOGL, and AMD maintained positive DWOI, nearly all individual stocks saw negative daily DWOI changes, indicating weakening bullish conviction. TSLA's DWOI contracted by -213K in a single day.

SMCI Extreme Volatility — IV at 1,150%

SMCI's implied volatility reached an extraordinary 1,150% with net DWOI at -370K and daily change of -373K. Such extreme IV levels typically correlate with major corporate events and warrant extreme caution.

Market Outlook

Today's data presents a classic "bullish stocks, bearish indices" divergence pattern. Institutional investors are maintaining bullish positions in tech leaders while simultaneously building massive hedges through index ETFs. The persistent VIX bullishness further confirms short-term volatility concerns.

Key Takeaways:

• Index ETF bearish DWOI far exceeds individual stock bullish totals — overall risk appetite declining
• VIX is the only security with positive DWOI growth — volatility expectations rising
• Tech stock DWOI remains positive but universally contracting — bullish momentum fading
• SMCI's extreme IV warrants close monitoring
