NEW YORK — Optimism for a definitive end to the conflict between the United States and Iran propelled Wall Street to historic levels on Wednesday, with major indices shattering records as investors bet on a swift diplomatic resolution.

In a landmark session on April 15 (local time), the S&P 500 closed above the 7,000-point threshold for the first time in history. The benchmark index climbed 55.58 points, or 0.80%, to finish at 7,022.95. During intra-day trading, it reached a peak of 7,026.24, further solidifying the market's bullish momentum.

The tech-heavy Nasdaq Composite also saw significant gains, surging 376.93 points, or 1.59%, to close at 24,016.02. This marked its highest finish in approximately six months and extended its winning streak to an impressive 11 consecutive trading days. In contrast, the Dow Jones Industrial Average experienced a slight pullback, shedding 72.27 points (0.15%) to close at 48,463.72, as investors rotated capital into growth-oriented sectors.

The "Trump Effect" and Geopolitical De-escalation
The primary catalyst for the day’s rally was a series of optimistic remarks from U.S. President Donald Trump. In a high-profile televised interview, the President stated that the war is "ending soon," providing a much-needed psychological boost to global markets.

These comments have effectively reversed the negative sentiment that had clouded the markets since the onset of the Middle East conflict. Analysts noted that the major indices have not only recovered all losses incurred during the peak of the wartime shock but are now entering a phase of sustained expansion.

Robust Earnings and AI Momentum
Beyond geopolitics, strong corporate fundamentals provided additional tailwinds. As the first-quarter earnings season gets underway, major financial institutions have reported results that significantly exceeded market expectations, reassuring investors about the resilience of the U.S. economy.

The semiconductor sector remained a key driver of growth. Shares in the industry rallied following news that a leading chipmaker secured an expanded supply contract for AI-specific processors with a major Big Tech firm. This development underscored the continuing influence of artificial intelligence on market valuations.

Economic Outlook and Energy Markets
The Federal Reserve, in its latest assessment, acknowledged that while the Middle East conflict remains a source of uncertainty for corporate decision-making, overall economic activity continues to trend upward. This balanced view from the central bank further mitigated fears of a potential slowdown.

In the commodities market, international oil prices remained relatively stable. The market was caught between two opposing forces: the expectation of decreased demand due to potential peace and a simultaneous decline in crude oil inventories.

As the possibility of a "peace dividend" grows, market participants are shifting their focus back to domestic economic indicators and the path of interest rates, while remaining watchful for any concrete diplomatic breakthroughs in the coming days.
