Wall Street closed lower on Friday after a report of slowing US labour market growth, and all three major indexes posted weekly losses as investors braced for more possible downside surprises a day after disappointing earnings from Apple.

Apple's shares fell 4.8 percent, its biggest daily percentage decline since September 29, 2022 that dented the S&P 500 by about 16 points the day after the iPhone maker forecast a continued slide in sales.

A partial counterweight to Apple for the S&P 500 and Nasdaq was Amazon.com. Its shares rose 8.3 percent the day after the online retailer issued an upbeat third-quarter outlook.

"Those big bellwether companies really have the potential to cause investor jitters even though overall the trajectory and direction of both the economy and corporate earnings seems to be positive moving into August," Said Greg Bassuk, chief executive officer of AXS Investments in New York.

The trading session was choppy, with the indexes rising in the morning, then wavering before turning negative. Bassuk said Friday's decline was "more about investors resetting and positioning for potential downside surprises".

The weekly percentage declines for the S&P and Nasdaq were the biggest since March, with some investors taking profits after five months of gains due to economic data, disappointing earnings and rising Treasury yields.
