5 Things to Watch on
April 20, 2026

U.S. stocks are down more than -0.4% while oil prices are surging again, up more than +5%, as hopes for a Strait of Hormuz resolution collapsed over the weekend. Iran had announced Friday it would reopen the vital chokepoint, sending oil prices plunging and vessels rushing for the crossing. The reversal came swiftly: the U.S. refused to lift its own blockade, and the Navy seized an Iranian cargo ship, the Touska, in the Gulf of Oman after it failed to comply with warnings, the first such incident since Washington adopted the blockade strategy seven weeks into the Persian Gulf war.

Marvell Technology (MRVL) is up more than +6% in premarket trading after reports that the chipmaker is in talks with Alphabet (GOOGL) to develop two new AI chips, including a memory processing unit to work alongside GOOGL's tensor processing units and a new TPU engineered for inference workloads. The news weighed on existing GOOGL chip partners Broadcom (AVGO) and Celestica (CLS), which slipped -1.5% and -1%, respectively. Analysts called the deal a "meaningful incremental positive" for MRVL, noting it would diversify its custom chip customer base beyond Amazon (AMZN) and Microsoft (MSFT).

Tesla (TSLA) is down -0.8% in premarket trading despite announcing over the weekend that it has expanded its robotaxi service to Dallas and Houston, bringing its Texas coverage to three cities alongside Austin, where the geofenced self-driving network has operated since last year. TSLA posted footage of a fully driverless Model Y without a safety monitor, though its San Francisco Bay Area service still deploys one. Further expansion is planned for Phoenix, Miami, Orlando, Tampa, and Las Vegas, with investors set to hear more during TSLA's earnings call on Wednesday.

PepsiCo (PEP) unveiled a major rebrand of Gatorade, shifting the iconic sports drink from an athlete-focused product to a broader everyday hydration platform with new packaging, cleaner formulas, and occasions like work and travel. The revamped lineup is organized by whether each drink hydrates better, faster, or longer than water, with a new Gatorlyte Longer Lasting product rolling out later this year and reaching national availability in 2027. The move expands Gatorade's addressable audience well beyond athletes, a potentially significant revenue lever for PEP's beverage portfolio.

Billions of dollars are set to flow back to American importers after the Supreme Court struck down President Trump's IEEPA tariffs in February, with a new claims portal launching today through U.S. Customs and Border Protection. Roughly 330K importers and 53M shipments are eligible for an estimated $166B to $175B in repayments, though refunds are expected to take 60 to 90 days. The trade fight is far from over: the administration is seeking to reinstate tariffs under different statutory authority, with Treasury Secretary Scott Bessent signaling levies could return to prior levels by early July.
