Notable tech headlines for the week: AMD, Qualcomm and Lumentum in focus

What happened

Technology stocks had a volatile week, and the Nasdaq Composite closed higher Friday as it led a recovery from its worst day in more than a year. Qualcomm shares plunged after smartphone chip revenue fell 26%; the company reported fourth-quarter adjusted earnings of $2.17 per share and revenue of $10.44 billion.

Confirmed

Global impact / market context

Qualcomm’s falling smartphone chip revenue, which the article links to higher memory prices and weaker handset demand, points to pressure on chip sales. If that demand weakness continues, revenue and profit per sale could remain under strain; the article also cites lost Apple modem share as a near-term risk.

Analyst inference

The article describes a broad technology sell-off alongside sharply different weekly share moves, followed by a Friday Nasdaq recovery. Qualcomm’s mixed outlook and Lumentum’s steep decline show company-specific results and risks coincided with sector-wide volatility; the article does not establish what drove Lumentum’s fall.

Analyst inference

What to watch

1. Watch Qualcomm’s next results for smartphone chip revenue and whether handset demand improves as memory prices weigh on buyers, since this could change its sales outlook. Analyst inference
2. Watch for details on Marvell’s intended all-stock Lumentum deal; the supplied article says it intends a deal but provides no terms or completion timeline. Proposed
3. Track whether Qualcomm’s guidance and analyst price-target changes reflect continuing margin pressure and Apple modem share losses, both identified as risks to its near-term outlook. Analyst inference
