Shares of industrial fluid and energy systems manufacturer Graham Corporation (NYSE: GHM) fell 2% in the afternoon session after the major indices continued to retreat (Nasdaq -1.5%, S&P 500 -1.2%) amid profit-taking and renewed concerns about tariffs. The sell-off was partly triggered by the latest ISM Manufacturing report, which showed activity in the sector shrinking for a sixth consecutive month. This news sparked a risk-off sentiment among investors, sending major indexes like the S&P 500 and Nasdaq down by more than 1%. Adding to the concerns, the ISM report highlighted executives' worries about unstable tariffs and a weakening global economy, which has led to decreased orders. The negative market-wide reaction to this economic data appears to be the primary driver behind the decline in Graham Corporation's shares, as no company-specific news was reported.

Graham Corporation’s shares are very volatile and have had 21 moves greater than 5% over the last year. In that context, today’s move indicates the market considers this news meaningful but not something that would fundamentally change its perception of the business.

The previous big move we wrote about was 14 days ago when the stock dropped 3.5% after investors took some profits off the table as markets awaited signals on future monetary policy from the Federal Reserve's Jackson Hole symposium later in the week. The downturn in the market was largely attributed to a significant sell-off in megacap tech and chipmaker shares.

Nvidia, Advanced Micro Devices (AMD), and Broadcom all saw notable drops, dragging down the VanEck Semiconductor ETF. Other major tech-related companies like Tesla, Meta Platforms, and Netflix were also under pressure. A key reason for this trend is that much of the recent market gains have been concentrated in the "AI trade," which includes these large technology and semiconductor companies. So this could also mean that some investors are locking in some gains ahead of more definitive feedback from the Fed.

Graham Corporation is up 9.4% since the beginning of the year, but at $48.31 per share, it is still trading 15.9% below its 52-week high of $57.43 from August 2025. Investors who bought $1,000 worth of Graham Corporation’s shares 5 years ago would now be looking at an investment worth $3,563.
