# Stock Market Today, April 20: Market Rebound Stumbles as Oil Disruption Continues

The **S&P 500** (SNPINDEX:^GSPC) fell 0.24% to 7,109.14, the **Nasdaq Composite** (NASDAQINDEX:^IXIC) slipped 0.26% to 24,404.39, and the **Dow Jones Industrial Average** (DJINDICES:^DJI) edged down 0.01% to 49,442.56 as optimism about U.S.-Iran conflict de-escalation faltered.

## Market movers

WTI crude jumped almost 6% to close at $88.85 per barrel, causing energy names to climb while travel stocks fell. **American Airlines** (NASDAQ:AAL) fell after it rejected a merger approach from **United Airlines** (NASDAQ:UAL) on Friday.

In tech, **Atlassian** (NASDAQ:TEAM) rallied after falling by almost 65% in the past year, potentially as investors look for opportunities. **AST SpaceMobile** (NASDAQ:ASTS) slumped after a flawed satellite launch.

**Apple** (NASDAQ:AAPL) fell in after-hours trading on news that CEO Tim Cook would step down in September. **Marvell Technology** (NASDAQ:MRVL) gained on reports of a possible artificial intelligence (AI) chip deal with **Alphabet** (NASDAQ:GOOG).

## What this means for investors

After last week’s new highs, markets lost steam today on concerns of renewed tensions in the Middle East. The current U.S.-Iran ceasefire is set to end on Wednesday evening, and further headline-driven volatility is likely. Transit through the crucial Strait of Hormuz remains heavily restricted, despite Friday’s brief hopes of a reopening.

Some economists fear a prolonged disruption to the oil supply could slow global growth. Wall Street will be watching upcoming earnings from heavyweights for signs that high energy prices are squeezing margins. **Tesla** (NASDAQ:TSLA), **UnitedHealth** (NYSE:UNH), **GE Aerospace** (NYSE:GE), and **AT&T** (NYSE:T) are all due to report this week.
