币界网报道：Coinbase's stock rating was downgraded by Oppenheimer from "Outperform" to "Perform" due to concerns over market volatility and regulatory uncertainty. Analyst Owen Lau cited declining trading volumes and potential risks from the SEC's ongoing scrutiny of crypto exchanges as key factors. The downgrade follows Coinbase's Q1 earnings report, which showed a 33% revenue drop year-over-year despite beating estimates. Lau noted the company's strong balance sheet and diversified revenue streams but expressed caution about near-term challenges in retail trading activity. The analyst removed his $160 price target, reflecting reduced confidence in the stock's performance amid current market conditions. This marks the second major Wall Street downgrade for Coinbase in recent months as traditional finance firms reassess crypto exposure. The exchange's shares fell approximately 3% following the announcement.
