NEW YORK/LONDON, Aug 25 (Reuters) - MSCI's global equities gauge rose on Tuesday as investors awaited economic data and Nvidia's financial results, while bond yields declined and oil prices fell following a U.S. threat to expand sanctions against Iran.
Yields on U.S. 10-year and 30-year bonds were set for a second straight day of declines as traders weighed the implications of U.S. Treasury Secretary Scott Bessent's decision last week to expand Treasury buybacks.
On Monday,
Bessent warned countries to cut their financial ties with Iran or face secondary sanctions as part of what had been billed as "economic D-Day." However, oil prices fell to a one-week low on Tuesday as traders viewed economic pressure as less of a risk to oil supplies than a military escalation.
On Wall Street, the heavyweight technology sector was poised to recoup some of Monday's losses, ahead of the release of second-quarter results from AI chip leader Nvidia after market close on Wednesday.
NVIDIA RESULTS PROVIDE A FOCUS
"Technology is stronger today after the recent weakness," said Tim Ghriskey, senior portfolio strategist at Ingalls & Snyder, noting that much of the boost was from Nvidia whose upcoming results are on investors' minds.
"Nvidia has been weak and its price to earnings valuation has been down. There are buyers of Nvidia here looking for a strong earnings report. Nvidia is helping to pull up the rest of the tech market."
The strategist also said Treasury yields were "moving in the opposite way they have been moving which is positive for the stock market," but that the move was modest.
