0252 GMT - Nvidia's results are a strong validation of the artificial-intelligence infrastructure trade, Saxo Markets chief investment strategist Charu Chanana says in a note. Memory, networking, optics, power infrastructure and selected cloud providers all benefit from continued capacity expansion, but there is increasing need to prove AI returns, Chanana notes. Memory remains one of the clearest beneficiaries, with Nvidia's margin guidance confirming that supply is still tight, she says. Asian memory stocks are broadly higher after the results, with SK Hynix gaining 3.4% and Samsung Electronics rising 2.3%. Still, the next leg of the memory trade increasingly depends on whether AI demand and memory content per accelerator can absorb the rising supply capacity rather than simply on shortages pushing prices higher, she adds.
