Market Index Analysis

  • Costco Wholesale Corporation (NASDAQ:COST) is a member of the NASDAQ 100 Index, the S&P 100 Index, and the S&P 500 Index.

  • All three indices recorded fresh all-time highs on bearish trading volumes, driven solely by AI-related companies, as the rest of the market underperforms.

  • The Bull Bear Power Indicator for the S&P 500 Index is bullish with a negative divergence.

Market Sentiment Analysis

Equity futures are wavering this morning but are mostly higher after Micron and SK Hynix topped $1 trillion in market cap for the first time, driven by the AI mania, which has pushed indices to record highs, a trend that could extend but slow its trajectory over the summer. Marvell Technology, Salesforce, Snowflake, and Abercrombie & Fitch will report earnings today, which could inject volatility.

Costco Wholesale Corporation Fundamental Analysis

Costco Wholesale Corporation is one of the world’s largest retailers and the largest retailer of beef, poultry, organic produce, and wine. Over 30% of Americans regularly shop at Costco Wholesale Corporation, which drives value through its in-house brand. It currently has 905 warehouses serving more than 130 million members.

So, why am I bearish on COST at current levels?

Costco Wholesale Corporation remains extremely overvalued and lacks medium-term bullish catalysts. I expect COST to beat its earnings estimates, but for the sell-off to accelerate, like Walmart (NASDAQ:WMT), as they face the same macro and consumer environment. Competition continues to increase, with reports indicating decelerating renewal rates for Costco’s membership.
