Near VIX 20market reversal amid sharp swings in semiconductor and technology stocks

U.S. stocks closed with a sharp reversal similar to Friday's pattern. Technology stocks turned lower after rising at the start of the session. The volatility index VIX approached 20.

Memory and semiconductor stocks showed weakness during the session. Some of the largest leading technology stocks turned negative by the close. Large technology stocks known as the 'Magnificent 7' weighed negatively on the day's overall returns.

Oil prices fell by more than 3% on expectations of an agreement with Iran. The news reflected market expectations that an agreement could be reached within 2~3 days. Energy-related indexes were affected by the move.

Market profit concentration remained high. The gap in profits between the top 20% and bottom 20% was observed to be increasing volatility. As a result, the market's own trading range widened.

The non-technology sector showed some recovery. A recovery across a broad range of sectors somewhat eased volatility in the index composition. However, overall volatility did not decline.

Overall, the market showed sectoral differentiation amid persistent short-term volatility. Investors monitored volatility indicators and crude oil flows. The influence of a single large-cap stock on the index determined the day's market trend.
