Nvidia’s post-earnings jump of 8.74% fuelled a technology-led rebound in US equities, pushing the S&P 500 up 0.72% and the Nasdaq up 1.57%. The S&P 500 finished within 1% of its record high, while information technology rose 3.40%. Beneath the headline move, breadth was weak: over two-thirds of S&P 500 constituents fell, and the equal-weighted S&P 500 declined 0.29% as every major sector outside information technology closed lower.
European markets also retreated as higher energy prices stoked inflation concerns. The STOXX 600 fell 0.69%, its worst session in a month, while France’s CAC 40 slid 1.68% as French lenders lagged, with BNP Paribas down 4.79%, Crédit Agricole off 3.97% and Société Générale lower by 4.99%. In Asia, the KOSPI dropped 1.24% and the CSI 300 edged down 0.10%, while the Nikkei climbed 0.75% and the Hang Seng gained 0.47%, alongside a 0.08% rise in the Shanghai Comp. US S&P 500 futures were down 0.04%.
Market Breadth and Seasonal Risks
We are seeing a market that looks healthy on the surface but is incredibly fragile underneath. While a massive jump in a few tech giants pushed the S&P 500 up, over 66% of the index’s stocks actually declined during the rally. This extreme divergence means we should not trust this market surge blindly.
Historically, September is the worst-performing month for the S&P 500, averaging a decline of about 1.2% since 1928. With the equal-weighted S&P 500 already dropping 0.29% as the main index rose, the broader market lacks the support needed to sustain these highs. Derivative traders should prepare for this seasonal weakness by targeting volatility.
Options Strategies for a Fragile Market
We suggest buying protective puts on major index ETFs like SPY or QQQ while implied volatility remains relatively cheap. The CBOE Volatility Index (VIX) historically climbs in September as trading volume returns after the summer lull. Buying near-the-money put options expiring in late September will help hedge against a sudden correction in mega-cap tech.
Another smart play is to trade the divergence between tech and weaker global sectors, especially with European banks under pressure. We can set up bear put spreads on equal-weighted indexes or weaker sectors to capture downside room without betting against tech momentum directly. This neutralizes our risk while positioning us to profit from a broader market rollover.
