An analyst from The Motley Fool predicts a future sell-off for Robinhood (HOOD) stock, even after it climbed over 45% from its 52-week low of $63 in March. The analysis points to Robinhood's revenue composition, which remains heavily reliant on volatile options, crypto, and prediction market trading. In Q2 2026, the company reported $1.3 billion in revenue (+32% YoY), with transaction-based revenue at $776 million. Crypto trading revenue, however, plummeted 38% to $100 million. Additionally, the stock's price-to-sales (P/S) ratio stands at an elevated 16.5, significantly above its long-term average of 11.9, suggesting potential downside.
