Hedge Fund Highlights
One highlight from last quarter is Point72 Asset Management’s sharp increase in Teradyne, with the firm boosting its position by roughly 1,371%. Led by founder Steven Cohen, Point72 now holds about $562M value in shares, which suggests it appears more constructive on Teradyne’s earnings trajectory and semiconductor testing exposure.
Hudson Bay Capital Management, founded by Sander Gerber, also raised its Teradyne stake significantly, increasing its position by approximately 772% to roughly $9.5M value. This move may reflect growing interest as demand visibility improves across advanced chip testing.
Ardsley Advisory Partners, led by founder Philip Hempleman, increased its Teradyne position by about 453%, bringing its stake to roughly $12M value. While still modest in size, the scale of the increase suggests rising conviction relative to its prior exposure.
Meanwhile, Alkeon Capital Management, founded by Panayotis Sparaggis, continued adding to its Teradyne stake, lifting its position by nearly 49% to around $395M value, which may indicate a longer-term view on Teradyne’s role in a gradual semiconductor capital spending recovery, and for investors highlights selective optimism rather than broad consensus.
