What stands out

Stocks closed the day lower but finished the month higher, a reminder that headline shocks and calendar flows can move price and mood in different directions. The Federal Trade Commission (FTC) suing Amazon grabbed attention, because a major antitrust action threatens parts of Amazon's retail and marketplace economics even as the Iran conflict keeps energy and geopolitical risk on the table. For long-term investors this clip matters because it forces a choice between reacting to legal headlines and sticking with the secular growth story under the hood.
