Upcoming Session: Tickers to Watch

01Walmart (WMT) — reported U.S. comparable-store sales excluding fuel up 2.6% with a 0.8 percentage-point headwind from lower drug prices, and the stock fell roughly 9% on Aug. 20. The U.S.-close selloff may not be fully priced in Asia; watch the Tokyo/HK open for elevated volatility and repricing among retailers.
02CAC 40 (FRA40) — JD Sports cut full-year pre-tax profit guidance to £700m–£800m from a prior upper limit of £850m after a 3.1% like-for-like sales decline and a 6.8% North American sales drop, sending JD shares down more than 14% and pressuring the CAC. The guidance landed in European hours; watch the NYSE open for potential spillover into U.S. retail and European-exposed names.
03U.S. 10-year yield (10Y) — the Treasury said it would at least double long-dated liquidity-support buybacks, helping pull the 10-year toward roughly 4.65% and the dollar index (DXY) toward about 98.83. With that liquidity signal still being absorbed across markets, monitor the next open for further adjustments and cross-asset spillovers.
04American Gold & Copper Inc. (AGCI) — signed a non-binding letter of intent to acquire the Shamrock Nickel-Copper Project from Homeland Nickel Inc. The LOI is preliminary and may not be fully parsed by offshore investors; watch the next open for volume-led revaluation of AGCI and small-cap miners.
