IDEX Beats the S&P 500 Year to Date, but Recent Weakness Shows

IDEX Corporation shares outperformed the S&P 500 over the year to Sept. 22, 2026, but fell behind the index over the prior three months. IDEX, traded on the New York Stock Exchange as IEX, gained 25.1% year to date and 38.2% over 52 weeks.

Over three months, IDEX shares lost 1.1%, while the S&P 500 rose 3.5%, according to Barchart’s comparison. The results show how the measurement window changes the picture: IDEX’s longer-term gains are strong, but its recent momentum has weakened.

The stock was also below its 50-day moving average, a measure of its average price over roughly 10 weeks, from early September. It remained above its 200-day average, which tracks a longer stretch of trading and can help show the broader trend.

Business results offer one reason investors have backed the shares this year. IDEX reported second-quarter sales of $920.6 million, up 6% from a year earlier, and adjusted earnings of $2.32 per share, a 12% increase.

Orders provided another positive signal. The company said total orders rose 28% organically, excluding acquisitions and currency effects, while orders in its Health & Science Technologies segment climbed 47%.

IDEX linked demand in that segment to data centers, semiconductors, and space and defense markets. The company raised its 2026 adjusted earnings outlook to $8.70 to $8.85 per share after the quarter.

The next test is whether those orders turn into sales and earnings while the share price regains short-term momentum. IDEX is scheduled to report its next quarterly results in November, according to the company’s investor calendar.
