The Newest Stock in the S&P 500 Is Obliterating Nvidia and Palantir This Year. Is It Too Late to Buy?

Robinhood Markets was added to the S&P 500 on September 22nd, following a year-to-date stock surge exceeding 200%. This strong market performance, however, contrasts with significant underlying business challenges, including a 20% sequential decline in Q2 2025 transaction revenue, particularly a 55% drop in crypto trading, and a shrinking monthly active user base. While net interest income grew 25% year-over-year due to increased client cash and margin loans, future headwinds from falling interest rates and potential market corrections are noted. The article concludes that the stock's current price-to-sales ratio of 30.8, well above its historical average of 10.2, represents an unsustainable multiple expansion, signaling a high risk of a sharp correction.

Analysis

Robinhood Markets' (HOOD) inclusion in the S&P 500 on September 22 follows a 208% year-to-date stock appreciation, yet this market performance is starkly misaligned with deteriorating core business fundamentals. The company's Q2 2025 transaction revenue, its primary business component, declined 20% sequentially to $539 million, driven by a 55% plunge in volatile crypto-related revenue to $160 million. This decline is compounded by a shrinking monthly active user base in the first and second quarters of the year. While net interest income grew 25% year-over-year to $357 million, this was due to record margin loans and client cash balances offsetting recent Federal Reserve rate cuts, a dynamic that is vulnerable to a market correction or economic recession. The most significant red flag is the stock's valuation; its price-to-sales (P/S) ratio has expanded to 30.8, roughly three times its historical average of 10.2. This extreme multiple expansion, coupled with declining revenue and user metrics, signals an unsustainable valuation and a high probability of a significant price correction, with the article noting a 67% stock decline would be required just to revert to its long-term average P/S ratio.

Key Decisions for Investors

• Investors should recognize the significant risk posed by the divergence between Robinhood's soaring stock price and its declining core fundamentals, specifically a 20% drop in transaction revenue and a shrinking user base.
• The stock's price-to-sales ratio of 30.8, triple its historical average, indicates an unsustainable valuation and a high probability of a sharp correction, making new long positions exceptionally risky at this level.
• Considering the heavy reliance on volatile crypto revenue and the vulnerability of net interest income to a market downturn, holders of HOOD may consider trimming positions to lock in gains, as the risk/reward profile has become unfavorable.
