“And Nvidia will decelerate,” he added, referring to the company’s hitherto strong earnings growth.
Monday’s decline follows disclosures on Friday that the chipmaker’s chief executive and co-founder, Jensen Huang, sold almost $95m worth of shares in the days shortly before and after it became the world’s most valuable company.
The trades were part of a previously scheduled “rule 10b5-1″ sale plan, which was set up in March, filings show.
Nvidia declined to comment on the sales.
The stock’s rapid ascent has prompted some sceptical observers to draw comparisons with Cisco, the networking equipment maker that briefly became the world’s most valuable company at the peak of the dotcom boom in March 2000.
Cisco lost around 80 per cent of its value in the subsequent year as the bubble burst and telecoms groups slashed their spending on broadband infrastructure.
The reversal for Nvidia has weighed on the broader chipmaking sector, with the PHLX Semiconductor Index down 6 per cent since Thursday.
The tech-dominated Nasdaq Composite stood 0.3 per cent lower in midday trade in New York.
But the broader stock market shrugged off Nvidia’s decline, with the blue-chip S&P 500 gaining 0.3 per cent and the small-cap Russell 2000 index, which has massively under-performed large-cap indices in recent months, up 0.8 per cent.
Manish Kabra, head of US equity strategy at Société Générale, said Nvidia’s sell-off on Monday constituted “a super-healthy development for the market”.
“Either the market rally broadens out or we form a bubble [in tech stocks] that we don’t yet have,” Kabra said.
