Weichai America Corp. has demonstrated a consistent pattern of selling activity in its recent SEC Form 4 filings, with no recorded purchases across its 97 reported transactions. The company’s trading activity is exclusively tied to Power Solutions International, Inc. (PSIX), with all transactions occurring between August 25, 2025, and September 11, 2025. During this period, Weichai America executed 25 sales, totaling $10,028,813.76 in value. Notably, the largest single sale occurred on September 11, 2025, amounting to $2,878,799.28, while smaller transactions, such as a $15,842 sale on August 26, 2025, reflect a range of trade sizes.
The selling activity was concentrated in late August and early September 2025, with multiple transactions occurring on the same dates. For example, on August 26, 2025, Weichai America conducted nine separate sales, including a $1,788,415.67 transaction and a $995,033.97 sale. Similarly, September 10 and 11, 2025, saw a flurry of activity, with six and four sales, respectively, including a $1,344,190.47 transaction on September 10 and a $617,983.76 sale on September 11. This consistent and concentrated selling pattern suggests a deliberate reduction in Weichai America’s holdings in PSIX during this period, with no indication of acquisition activity. The absence of buying transactions underscores a clear directional bias toward divestment.
