Waters Corporation (WAT) closed Tuesday at $440.20, a gain of 3.50% over the prior 24-hour period. The advance pushed the company's market capitalization to $41.78 billion.
Zooming out, the picture is mixed. Over the past seven days, shares are down 0.62%, reflecting some near-term softness. However, the 30-day window tells a more constructive story, with WAT adding 7.49% over that stretch.
Waters Corporation develops and manufactures analytical instruments, software, and services used primarily in life sciences and other industries. The stock's one-month gain suggests sustained buying interest even as the shorter-term trend showed a modest pullback heading into Tuesday's session.
As of October 6, 2026, WAT's price of $440.20 represents the net result of those competing timeframes, with the daily gain recouping a portion of the week's earlier losses against a backdrop of solid monthly performance.
