United Microelectronics (UMC) hit a 52-week high, rallying almost 10% on Wednesday's session after posting 2.3% year-over-year growth. As George Tsilis explains, the AI chip fabricator's unique positioning in the tech trade gave bulls more incentive to run. He makes comparisons in UMC to TSMC (TSM) and ASML Holding (ASML) as the company works on building up its balance sheet.
