🇺🇸 U.S. Stock Market

Big Three Close (April 22 Session)

The S&P 500 and Nasdaq Composite both ended at all-time highs on April 22, fueled by President Trump's declaration of an indefinite extension of the U.S.-Iran ceasefire. Tech-led strength dominated, spreading rally momentum across the broader market. The Dow Jones finished with modest gains, approaching record territory. However, after-hours Tesla reported worse-than-expected earnings, immediately reversing futures into negative territory and raising anxiety ahead of April 23's open.

Key Moves (April 22 Close)

• Tesla (TSLA): Weakness post-close — After-hours earnings miss spooked futures to the downside
• S&P 500 overall: New high — Ceasefire extension boosted risk appetite, concentrated tech buying
• Nasdaq Composite: New high — Large-cap tech strength approaching 15 consecutive trading days of gains since 2009

Sector Trends

Tech and growth stocks bore the brunt of Middle East risk relief, while energy oscillated with oil prices. As earnings season hits full stride, sector divergence based on big tech results is widening.

🌏 Asia & Europe Stock Markets

Asia (Japan, China, Hong Kong)

Despite the U.S.-Iran ceasefire extension announced on April 22 (Wed), Asian markets slipped across the board as uncertainty over conflict sustainability lingered. Both the Nikkei 225 and Hong Kong Hang Seng endured corrections. On April 23 (Thu), reports of a U.S. military seizure of an Iranian tanker reignited broad selling pressure across Asia; the KOSPI widened losses from intraday highs.

Europe (United Kingdom, Germany, France)

On April 21 (Tue), European markets tumbled as investors waited to gauge the trajectory of U.S.-Iran peace negotiations. Major indices including the FTSE 100 and DAX fell in tandem, with geopolitical uncertainty dominating risk-off sentiment.

📊 Today's Market Drivers

• U.S.-Iran Ceasefire Extension & Tanker Seizure: President Trump declared on April 22 that the U.S.-Iran ceasefire would be extended indefinitely, triggering broad risk-asset buying globally. However, the same day brought reports of a U.S. military tanker seizure, sparking a sharp sentiment reversal on April 23. With peace talks now on hold, whether the truce actually holds has become the market's biggest wild card.

• Tesla Earnings Shock: Tesla's post-market earnings on April 22 missed expectations, prompting S&P 500 futures to reverse course right after hitting new highs. The miss underscored earnings season volatility and triggered caution heading into April 23's open.

• Fed Rate Path Uncertainty: Concerns over oil-driven inflation have dramatically cut investor expectations for Fed rate cuts this year to below 10bp (one cut or less). Market logic that strong corporate profits can sustain equities even in a high-oil, high-rate environment has been the cornerstone of the recent rally—but earnings season is now the ultimate test of that thesis.

🔭 What to Watch Next

Major Events This Week
