Trade Secrets: Dailies 05.27.2026

US stock futures wavered as investors watched for updates on negotiations between the US and Iran.
In day trading on Tuesday, the S&P 500 (^GSPC) and Nasdaq Composite (^IXIC) both rose to record highs. Optimism that the US and Iran could reach a lasting peace agreement somewhat soon, as well as confidence in the chip trade, lifted markets.
A conclusive end to the US-Iran war, however, remains murky, with Secretary of State Marco Rubio cautioning that any deal would likely take a few days to formalize. In the meantime, the Strait of Hormuz remains mostly shut to commercial traffic.
Earnings season continues to wrap up this week, with Marvell Technology (MRVL), Salesforce (CRM), Snowflake (SNOW), and Abercrombie & Fitch (ANF) set to report their results Wednesday.
Asian stock markets were mixed on Wednesday, with Japanese and South Korean shares scaling fresh record highs on the back of Wall Street’s technology-driven rally, although uncertainty over a possible U.S.-Iran peace agreement kept broader investor sentiment cautious.
Wall Street’s S&P 500 and NASDAQ Composite closed at all-time highs overnight.
Japan’s Nikkei 225 climbed as much as 2.2% to a new record high of 66,428.81 points, while the broader TOPIX index traded flat.
South Korea’s KOSPI surged 5% to a fresh record of 8,457.9 points, as an AI-fuelled rally in chipmakers gathered pace.
Shares of SK Hynix (KS:000660) jumped nearly 14%, pushing the company’s market capitalisation above $1 trillion for the first time and joining rivals Samsung Electronics (KS:005930) and Micron Technology (NASDAQ:MU) in the trillion-dollar club.
Samsung Electronics shares also hit a record high, climbing as much as 8%, after unionised workers approved a contentious wage and bonus agreement that averted a potentially disruptive strike.
Technology shares across the region continued to benefit from optimism surrounding artificial intelligence spending after Micron Technology rallied sharply on Wall Street following a bullish brokerage upgrade.
Still, gains in regional equities were capped by concerns that renewed U.S. military strikes on Iranian targets could derail negotiations aimed at ending the Middle East conflict.
Oil prices remained volatile, with Brent crude hovering near $99 per barrel amid continued supply disruptions through the Strait of Hormuz.
China’s Shanghai Composite fell 1.1%, while the blue-chip Shanghai Shenzhen CSI 300 index eased 0.7%.
Hong Kong’s Hang Seng index slipped 0.8% despite chipmaking stocks advancing.
India’s Nifty 50 ticked 0.1% higher. Singapore markets were closed for a public holiday.
Australia’s S&P/ASX 200 edged up 0.2% after data showed underlying consumer prices rose 3.4% year-on-year in April, from 3.3% in March, reinforcing views that the Reserve Bank of Australia may keep interest rates elevated for longer.
Elsewhere, the Reserve Bank of New Zealand kept its official cash rate unchanged at 2.25% but signalled that future rate hikes would likely be needed sooner and by more than previously expected due to mounting inflation pressures from higher energy costs.
The central bank warned inflation could peak at 4.3% later this year as the Middle East conflict drives up fuel and petrochemical prices, even as economic growth weakens.
New Zealand’s NZX 50 index rose 0.9%.
Globally, investors awaited further developments in Middle East diplomacy and upcoming U.S. inflation data on Thursday.
