Shannon River, a New York-based hedge fund, recently sold roughly $44 million worth of InterDigital (IDCC) stock during the fourth quarter (the three months ending on Dec. 31, 2025). That reduced its position in the technology stock by about 75%. Here’s what it means for investors.
First off, we should recognize that IDCC stock has been on quite the run. Over the last three years, shares have advanced by 397%, equating to an exceptional compound annual growth rate (CAGR) of 69.4%. Therefore, it’s possible, and perhaps likely, that Shannon River is simply taking profits in a stock that has delivered astonishing returns.
Looking ahead, there are a few things investors should know about IDCC stock. In the plus column, the company is riding high. Revenue and net income are both near record-high levels. IDCC has secured several key legal victories ensuring the ability to monetize its patent portfolio. What’s more, management has provided upbeat revenue and earnings guidance for 2026.
On other hand, the stock’s long run of success could prove a new challenge. In particular, the stock’s valuation is now gaining increased scrutiny. IDCC’s price-to-earnings (P/E) multiple now stands at 30x. That’s near its highest level in three years and nearly double its three-year average PE multiple of 17x.
In summary, Shannon River’s sale of IDCC is likely prudent portfolio management. After all, on balance, IDCC’s overall business fundamentals look solid given its near-record revenue and its bullish guidance. However, valuation concerns could temper demand for IDCC stock at its current level.
