Emerald Advisers LLC has significantly reduced its holdings in Rambus Inc., selling 133,749 shares during the first quarter, a 21.3% reduction in its stake. The sale was disclosed in a recent filing with the Securities and Exchange Commission on July 14, 2026. Following the sale, Emerald Advisers still holds 493,236 shares, valued at approximately $42.4 million.
This news of institutional selling follows a period of volatility for Rambus stock, which experienced a sharp decline on July 13 after the company received an antitrust subpoena from the U.S. Department of Justice. The combination of the regulatory probe and the reduced position from a significant investor is drawing scrutiny from the market. A separate filing also indicated that Emerald Mutual Fund Advisers Trust cut its position by 21.5%.
