Key Highlights

• A broad semiconductor rebound is lifting AMD (NASDAQ: AMD), Qualcomm (NASDAQ: QCOM), Teradyne (NASDAQ: TER), ON Semiconductor (NASDAQ: ON), Microchip (NASDAQ: MCHP), and Monolithic Power Systems (NASDAQ: MPWR).

• Bank of America's characterization of last week's Meta-driven selloff as a temporary adjustment has helped restore sector-wide investor confidence.

• The rebound follows an over 11% two-session drop in the Philadelphia Semiconductor Index tied to AI infrastructure oversupply fears.

A single research call from Bank of America, characterizing last week's sharp semiconductor sector selloff as a temporary adjustment, appears to have played an outsized role in driving a broad-based rebound across chip stocks to start the new week.

The scale of the rebound is notable across multiple names. ON Semiconductor surged alongside AMD, up over 9%, and TSMC, rising approximately 4.8% amid Citigroup's expectations of upward revenue guidance revisions. Microchip Technology also gained, building on a May earnings beat that saw multiple analysts raise price targets to $120.

Qualcomm led the rebound with a near 6% gain, aided by Barclays' dramatic upgrade from Underweight to Overweight and a price target increase from $150 to $245. Teradyne, meanwhile, staged a sharp recovery after shedding roughly 14% the prior week, with Goldman Sachs lifting its target to $465 from $350.

Monolithic Power Systems also outperformed, surging over 6% and sharply beating both the broader semiconductor sector and the technology ETF XLK, supported by a strong first-quarter earnings beat of its own.

The common thread across all of these moves is the prior week's selloff, triggered by fears that AI hyperscalers like Meta were monetizing excess compute capacity, which had sent the Philadelphia Semiconductor Index down over 11% in two sessions. BofA's more constructive framing appears to have given multiple analysts across different firms the confidence to reaffirm or raise their targets, driving the coordinated rebound seen across the sector this week.

Taken together, this week's rebound illustrates how quickly sentiment can shift across an entire sector on the back of a single supportive research call, even as the underlying debate over AI infrastructure demand and potential compute oversupply remains far from fully resolved.

Cross-referencing moves in equipment names like Teradyne against pure chip designers such as AMD and Qualcomm can offer investors a more complete picture of where in the AI supply chain the current rebound in sentiment is concentrated.
