Berkley W R Corp Q2 2026 Investment Activity: Major Buys in TSM, PFE

According to the latest filing from Berkley W R Corp, there were observable changes in their investment portfolio during Q2 2026. The investor demonstrated significant buying activity, establishing new positions or increasing existing ones notably with Taiwan Semiconductor Manufacturing Corporation (TSM) and Pfizer Inc.

The purchase of TSM represents a substantial allocation at 1.21%. This indicates the firm's confidence in this technology sector player. Similarly, Berkley W R Corp significantly increased its stake in Pfizer Inc., acquiring shares that pushed its portfolio weight to approximately 1.19%, reflecting potential interest in the pharmaceutical giant.

In contrast, the investor also showed strong selling activity during Q2 2026. The most significant reduction occurred in NVIDIA Corporation (NVDA), where they sold a large portion of their holdings, resulting in an approximate 71.83% decrease from the previous quarter and lowering its portfolio allocation to just 1.27%. This suggests a strategic divestment or profit-taking decision.

Furthermore, Tesla Inc. (TSLA) experienced a substantial reduction in its holdings by Berkley W R Corp, with an approximate 62.5% decrease and the stock's portfolio allocation dropping to 1.07%. This is one of two exits noted for this quarter.

The investor also reduced their position in Microsoft Corporation (MSFT) slightly by about 2.1%, leading to a small reduction from its previous allocation, and sold some Amazon.com Inc. (AMZN), although the impact was less pronounced than on Tesla or NVIDIA.

Additionally, Berkley W R Corp initiated a new position in Bayview Acquisition Corp. (BAYA) with just 0.09% portfolio weight, indicating minimal significance for this investment vehicle during Q2 2026.
