Allegro Microsystems is trading 4.44% higher at $36.94 as investors position ahead of fiscal Q2 2027 results. - Results are scheduled for release before the market open on October 29, with a conference call at 8:30 a.m. ET; the release is not yet confirmed in available pre-market information. - Prior-session gains were also linked to chip-sector optimism and Allegro’s AI data-center products, but weak semiconductor futures make that backdrop a less likely explanation for the current gain.
