NEW YORK CITY, RAW – The Nasdaq has ended at a record high, lifted by Amazon, Microsoft and other top-shelf tech companies as investors shifted their focus to growth stocks.

Microsoft rose 1.1 per cent and its stock market value briefly breached $US2 trillion ($A2.6 trillion) for the first timewhile Apple, Facebook and Amazon also rallied more than 1.0 per cent each.

So-called value stocks, expected to benefit from the economic recovery, have outperformed in 2021 while growth stocks, including major tech names like Apple and Nvidia, have rallied since the Fed last week took a stance on future rate hikes viewed by many as more aggressive than expected.

The S&P growth index has added almost 2.0 per cent since before the Fed last Wednesday projected an accelerated timetable for interest rate increases compared with a drop of almost 2.0 per cent in the value index.

“The market was caught off guard regarding the Fed’s hawkish commentary, and that’s 100 per cent of what is happening,” said Andrew Mies, chief investment officer of 6 Meridian.

“All the smart people were surprised about how hawkish the Fed was, and now they are adjusting their portfolios.”

Nine of the 11 major S&P sector indexes rose, with consumer discretionary and tech the biggest gainers, each up about 1.0 per cent.
