Investors were optimistic during today’s trading session about the meeting between U.S. President Donald Trump and his Chinese counterpart Xi Jinping. Technology and semiconductor stocks rose in hopes of improving market conditions and strengthening the trade partnership between the United States and China.

Technology stocks have long attracted investors, helping drive their prices higher, especially with increasing investments in smart computing and artificial intelligence technologies worldwide, and the concentration of massive capital from global companies in this sector in particular.

However, economists are concerned about the existence of a price bubble in this sector — meaning an exaggerated and unrealistic valuation of these stocks — which could later lead to a sharp decline in prices. This could indeed happen if these markets fail to justify all the investor attention and strong confidence in the advancement of artificial intelligence.

As the European session approaches its close, London market stocks appear to be performing well. Germany’s DAX index rose by 1.39%, while the UK’s FTSE 100 also gained 0.39%. The Euro Stoxx index followed the same trend, rising by 0.98%.

In Asia this morning, performance was mixed. Japan’s Nikkei index fell by 0.98%, while China’s Shanghai index declined by 1.52%. Meanwhile, Australia’s ASX 200 and Hong Kong’s Hang Seng index remained relatively stable.

Technology stocks showed gains yesterday evening on the New York Stock Exchange. The Nasdaq 100 index rose by 1.04%, while the S&P 500 advanced by 0.58%. In contrast, the Dow Jones Industrial Average slipped slightly by 0.14%.

Investors hope this visit will positively impact global trade and the energy supply crisis resulting from the outbreak of war in Iran. China is the world’s largest oil importer, and China, Iran, and Russia are among the key Eastern bloc countries competing against U.S. global dominance.

Recent reports indicated rising prices in the United States, as both the Consumer Price Index (CPI) and Producer Price Index (PPI) for April came in higher than expected. Meanwhile, retail sales data were largely in line with expectations, although they declined compared to previous readings. Despite this, forecasts suggest a lower likelihood that the Federal Reserve will ease its monetary policy this year.

On another front, the U.S. Energy Information Administration’s report on crude oil inventories for last week showed a decline in stockpiles. If this decrease continues, the United States will require additional energy supplies, which would naturally push prices higher.
