ATI Shares Plunge 18.36 as $660M Surge in Trading Volume Ranks 205th Amid Expanded Boeing Titanium Supply Pact

On July 31, 2025, ATI (NYSE: ATI) closed with a 18.36% decline, despite a 112.41% surge in trading volume to $660 million, ranking 205th in market activity. The drop followed a major strategic update: the company extended and expanded its long-term titanium supply agreement with Boeing, solidifying its role as a key supplier of aerospace-grade materials. The deal covers Boeing’s narrowbody and widebody commercial aircraft programs and includes titanium alloy sheet production from ATI’s new South Carolina facility. CEO Kimberly Fields emphasized the agreement’s alignment with growing demand for high-strength titanium alloys and the company’s capacity expansion efforts.

The partnership reinforces ATI’s position in critical aerospace applications, with its materials present on nearly all commercial aircraft in operation. The agreement also positions ATI to support Boeing’s third-party subsidiaries, broadening its market reach. Management highlighted the strategic integration of Specialty Materials and Specialty Rolled Products divisions to deliver differentiated solutions. While the financial terms were not disclosed, the expansion underscores ATI’s focus on scaling production to meet rising aerospace industry needs, particularly as global air travel recovery accelerates demand for advanced materials.

The strategy of purchasing the top 500 stocks by daily trading volume and holding them for one day delivered a 166.71% return from 2022 to the present, outperforming the benchmark by 137.53%. This success is attributed to capturing liquidity-driven momentum, as seen in high-volume stocks like ATI. The approach reflects the current market’s emphasis on short-term liquidity shifts, though its effectiveness may vary as market dynamics evolve. For ATI, the surge in trading activity on July 31 aligns with this trend, suggesting investor focus on its strategic positioning in the titanium supply chain amid aerospace sector growth.
