The S&P 500 and the Nasdaq close at records, as chip stocks including Marvell rise

The S&P 500 rose 0.58% and the Nasdaq Composite 0.45%, Reuters and the Motley Fool reported. It was the S&P's first record close since August, Yahoo Finance said.

The S&P 500 rose 0.58% on Tuesday 6 October and the Nasdaq Composite rose 0.45%, and both closed at all-time highs, Reuters reported in a story carried by Yahoo Finance. The Motley Fool, also on Yahoo Finance, reported the same moves. The index providers' own closing data was not opened from here, so the figures are reported.

It was the S&P 500's first record close since August, Yahoo Finance's live coverage said, and the Nasdaq's record was its second in a row, following a record close the day before, Yahoo Finance said.

Chip stocks rose. Marvell Technology climbed 5.8% after raising its fiscal 2028 revenue forecast, Reuters reported, and the Motley Fool gave the same gain. The Switchboard covers Marvell's new targets under the same date.

The records came the day after Taiwan's stock market record of 5 October, which the Switchboard covered, and show investors still paying up for AI hardware. Exact index levels differed by a few hundredths of a point between the two outlets, so only the percentage moves are given here.
