Charts We Liked (And Didn't Like) Last Week

Elevated S&P 500 short interest, at the 95th percentile of its five-year range, indicates persistent caution on the broader market, even as breadth improves with more stocks hitting 52-week highs. Despite a recent SPX pullback from its +10% level post-PPI, tech valuations are growing at twice the money supply, nearing dot-com bubble levels, creating a complex outlook amidst returning institutional capital and ongoing inflation/tariff concerns. This mixed environment, underscored by Applied Materials' 14% after-hours drop on weak Q3 guidance, necessitates investor nimbleness and hedging strategies.

Analysis

The market is exhibiting a significant divergence between price action and underlying sentiment. While the S&P 500 is near all-time highs, short interest on the index has reached the 95th percentile of its five-year range, a level of pessimism that starkly contrasts with the positioning on the Nasdaq-100 (70.5th percentile) and Russell 2000 (93.3th percentile). This suggests concentrated hedging or bearish bets against the broader market. Despite this caution, there are signs of improving market breadth, with more constituents reaching 52-week highs, challenging the narrative of a rally driven by only a few mega-cap stocks. However, valuation risks are pronounced, particularly in the technology sector, where value is growing at twice the rate of the money supply, nearing levels reminiscent of the dot-com bubble. The market's sensitivity to forward-looking data was highlighted by Applied Materials (AMAT), which dropped 14% after-hours on weak Q3 guidance despite a Q2 earnings beat, reinforcing that future outlook is paramount. This environment, complicated by inflation and potential tariff overhangs, creates a complex dynamic where bullish momentum coexists with substantial underlying risk.

Key Decisions for Investors

• Given the elevated S&P 500 short interest and stretched technology valuations, investors should review portfolio hedges and consider strategies to protect against a potential market pullback or sector rotation.
• Monitor heavily shorted stocks such as RKLB, OKLO, and MP for any positive catalysts, as the significant short interest presents the potential for a short squeeze, but be aware of the inherent risks that attracted short-sellers.
• The market's severe punishment of Applied Materials' weak guidance underscores the need to prioritize forward-looking statements over historical performance during earnings season, as outlook is the primary driver of price action.
• Pay close attention to market breadth indicators, as continued improvement would signal a healthier, more sustainable rally, potentially warranting broader market exposure beyond mega-cap technology.
