NEW YORK, Nov 15 — Several hedge funds expanded their bets on big technology stocks including Amazon, Microsoft and Meta Platforms even as these companies stumbled some during the third quarter after having fuelled broad market gains this year, new regulatory filings show.

Tiger Global Management, a widely watched fund in the investment world, increased its holding of Nvidia, whose semiconductors back artificial-intelligence systems, by 77 per cent during the third quarter. It boosted its bet on Alphabet by 40 per cent, the filings show.

The firm also raised its Meta investment by 4 per cent, boosted its bet on Microsoft by 8 per cent and increased its Amazon stake by 6.5 per cent.

Tiger Global and other hedge funds nursed heavy losses in 2022 when technology stocks skidded lower. But many fund managers put more money to work in the sector this year when seven big tech stocks raced higher, playing a critical role in helping the broader stock market recover after last year’s drop.

Bill Ackman, whose Pershing Square Capital Management is widely followed for investment clues, reported raising his stake in Alphabet Inc Class A shares by nearly 100 per cent to own 4.4 million shares at the end of the quarter.

Coatue Management, founded by Philippe Laffont, increased its position in Meta by 9 per cent to own 6.2 million shares on September 30, the filings show.

Glen Kacher’s Light Street Capital increased its position in Amazon by 5 per cent after having reported a new position in the online retailer in the second quarter.

Ratan Capital Management reported even bigger increases, saying it increased its Amazon holding by 72 per cent and boosted its Meta stake by 67 per cent. The fund also reported a new position in Alphabet, saying it owned 20,000 shares on September 30.

Goldman Sachs reported in late August that hedge funds held record exposure to the seven biggest tech stocks by market capitalization.

2023 has been a better year for investors, with the S&P 500 .SPX stock market index up 18 per cent since January after a 20 per cent drop in 2022. The rally has been largely fuelled by a small number of companies — the so-called magnificent seven.

Since January, Meta’s share price has surged 169 per cent while Amazon gained 70 per cent and Microsoft is up 53 per cent.

Investment managers must disclose what they hold in US stocks at the end of each quarter and report that information to the Securities and Exchange Commission 45 days after the end of the quarter. The deadline for so-called 13-F filings for the third quarter is yesterday.

While 13-F filings are backward-looking, they are closely watched by investors for trends.

But investors, many of whom suffered big losses only last year, also showed caution during the third quarter when markets stumbled some and certain tech stocks lost some ground.

Light Street cut its stake in Meta by 31 per cent after having increased it 27 per cent in the second quarter and Coatue cut its stake in Microsoft by 28 per cent and reduced its stake in Amazon by 15 per cent.

Representatives for the funds did not immediately respond to requests for comment. — Reuters
