Movement in the stock market will hinge on the outcome of talks between the US and Iran, crude oil prices and trading activity of foreign investors in the holiday-shortened week ahead, analysts said. Technical-level talks will be held in Burgenstock, Switzerland, on Sunday between the US and Iran. US Vice President JD Vance was initially supposed to hold a first round of talks with senior Iranian officials on Friday at a mountainside resort in the tiny Swiss village of Obburgen, but his Iranian counterparts cancelled their plans to attend because of escalating fighting between Israel and Iranian-backed Hezbollah in Lebanon.
