October 2025 saw the Dow Jones Industrial Average's 30 stocks on a rollercoaster ride. Some soared, others stumbled. Let's dive into the three biggest losers.

Apple Inc. took a 4.8% hit. iPhone production hiccups were to blame. Demand stayed strong, but supply chain issues got in the way. Sales targets? Missed. Stock price? Down. But hey, analysts aren't losing sleep. They're all about that Apple ecosystem and AR stuff on the horizon.

Boeing Company slipped 3.9%. Delivery delays and 787 Dreamliner quality control raised eyebrows. Regulators weren't thrilled. It's not all doom and gloom, though. Their order book's still chunky, and space ventures are looking up.

Walmart Inc. dropped 3.5%. Quarterly earnings didn't wow anyone. Labor costs went up, inflation kept biting. Kind of a bummer. But there's a silver lining - e-commerce is booming. Management seems pretty chill about their game plan to blend online and in-store shopping.

These dips didn't sink the Dow, though. Other stocks picked up the slack. The index kept climbing. Investors? They're keeping their eyes peeled, watching the economy and company news like hawks. Blue-chip stocks are always a wild ride.
