The semiconductor sector experienced a dramatic three-week reversal, swinging from a significant sell-off to a rally that added over $400 billion in market value. The catalysts were strong earnings from Micron Technology and an ambitious long-term forecast from Qualcomm, reminding Wall Street the AI trade remains potent.
Micron's fiscal Q3 results were stunning, with revenue surging 346% year-over-year, driving shares up roughly 15-17% in after-hours trading. Qualcomm, meanwhile, projected $15 billion in data-center revenue by fiscal 2029 and raised its overall non-handset revenue target to $40 billion, signaling a major strategic shift beyond its traditional smartphone modem business.
This volatility highlights the market's sensitivity to new information. On June 4th, the sector was hammered on AI valuation concerns, with Micron dropping over 7%. Just weeks later, blowout earnings triggered a massive after-hours surge.
The partnership between Micron and Qualcomm to supply LPDDR5X memory for Snapdragon platforms points to a vertical integration trend in AI hardware, where controlling both processing and memory could offer competitive advantages. Analysts note that memory chips are becoming a critical bottleneck and profit center in AI infrastructure.
For investors, the key indicator to watch is quarterly capital expenditure guidance from major cloud providers, as it signals the durability of the current massive wave of AI infrastructure investment.
