How does corporate merger and acquisition activity affect stock prices?

Stock prices of listed companies rumored to be involved in M&A activities typically react to such rumors, with most experiencing an upward trend. Two main reasons drive this phenomenon: first, investors anticipate improved post-merger performance; second, some investors speculate on the M&A event itself, driving up share prices. For example, Julong Pipe Industry announced in May 2014 its acquisition of mobile game developer Eglis. Its stock price rose from RMB 13 to approximately RMB 24. Without market speculation surrounding the M&A announcement, such a sharp increase would likely not have occurred. 2. Stock price increases usually occur before the official M&A announcement. Stock prices generally rise prior to the formal announcement of an M&A deal, but the upward momentum tends to slow—or even reverse into a decline—after the announcement. This occurs because insiders—including certain company employees and individuals involved in the M&A—may leak confidential information to select market manipulators ("big players") before the official announcement. These manipulators then artificially inflate the stock price through speculative trading. Once the announcement is made, they quickly sell their shares to lock in substantial profits, shifting the risk onto retail investors. 3. The acquiring company’s strength and industry sector significantly influence stock price volatility. Generally, stronger acquiring companies operating in more promising industries are more likely to trigger stock price increases following an M&A announcement; conversely, weaker companies or those in less promising sectors may see their stock prices fall. This is because stronger companies operating in high-potential industries generate higher investor expectations for post-M&A earnings growth. Consequently, M&A deals involving strong companies in attractive industries tend to attract investor attention and enthusiasm, pushing up share prices. In contrast, weaker companies or those in stagnant industries produce the opposite effect.

What should Chinese raw-material companies learn from Ashland’s potential sale?

A century-old company supplying specialty raw materials to global giants like L’Oréal and Pfizer has recently been placed on the auction block by Wall Street. On June 9, U.S.-based activist investment firm Ancora Alternatives publicly urged Ashland to consider a full sale. Its rationale: Ashland possesses high-quality businesses and valuable customer assets, yet the market has failed to assign them appropriate valuations; under new ownership, these assets could command significantly higher value. That same day, Ashland’s stock rose over 6%. Nine days later, another activist fund, Cruiser Capital, followed suit, formally proposing a sale to Ashland’s board. On July 28, Ashland reached an agreement with Ancora: two independent directors backed by Ancora joined the board, and the company established a Capital Allocation Advisory Committee. By August, Bloomberg reported that Ashland had begun exploring a potential sale after receiving expressions of acquisition interest. From public pressure to board representation to active exploration of a transaction, the entire process took just two months. Thus, a global specialty chemicals company was thrust from behind the scenes into the spotlight. FBeauty Future Trace argues that Ancora succeeded in launching this campaign because Ashland’s underlying assets remain attractive—even as its operational results have persistently disappointed public-market investors. For Chinese cosmetics ingredient companies accelerating their entry into capital markets, this contradiction is far more instructive—and cautionary—than the acquisition itself. Why was Ashland placed on the 'auction block'? Ashland’s current predicament can be summarized in one sentence: it owns excellent assets but has failed to fully convert them into visible, sustained growth for shareholders. Founded in the 1920s, Ashland has long focused on high-value-added markets including life sciences, personal care, coatings, and specialty additives. In cosmetics, its products span cellulose derivatives, film-forming agents, bioactive ingredients, and preservative systems; in pharmaceuticals, many of its products require lengthy customer qualification periods. Such businesses share a defining trait: gaining entry into a customer’s supply chain is difficult—but once achieved, replacement costs for the customer are high. In its June public statement, Ancora noted that Ashland holds high-quality end markets, mature customer relationships, and defensible assets—yet its stock price had plunged nearly 50% since late 2022. To Ancora, the public-market valuation had fallen below the potential control-value of these assets. The root problem lies in operations…
