U.S. major stock indices began to fall.

As of 9:47 a.m. on the 20th (Eastern Time), the Dow Jones Industrial Average recorded 42,694.80, down 97.27 points (0.23%) from the previous session at the New York Stock Exchange (NYSE).

The S&P 500 index is down 23.61 points (0.40%) at 5,939.99, while the Nasdaq index is moving down 113.24 points (0.59%) at 19,102.22.

Generally, all sectors started lower.

Information technology is down 0.8%, while real estate and energy are down around 0.4%. In contrast, utilities are up 0.3%. Global quantum computing corporation D-Wave Quantum is seeing its stock surge 22% after officially launching its next-generation quantum computer system "Advantage2."

So far, the market has continued its upward trend despite negative factors such as tariff burdens, concerns about a U.S. recession, and Moody's downgrade of the U.S. credit rating outlook. As a result, some are raising caution about overheating.

Ryan Dietrich, chief market strategist at Carson Group, noted, "Concerns about the market are realistic" and added, "The important thing is the movement of the market." He diagnosed, "In the past 27 trading days, the S&P 500 has risen about 20%," and explained that "this is neither a rebound in a bear market nor a technical rebound due to the unwinding of short positions."

Meanwhile, European stock indices are all rising today. The Euro Stoxx 50 index is up 0.69% compared to the previous session. The German DAX index is up 0.54%, the British FTSE index is up 0.84%, and the French CAC 40 index is up 0.79%.

International oil prices have shown a downward trend for two consecutive days this week. As of 9:40 a.m. today, the price of the near-month June West Texas Intermediate (WTI) crude oil is down 0.10% at $62.63 per barrel, while the price of the global benchmark Brent crude for July delivery is down 0.27% at $65.36 per barrel.
