Abstract:** The US stock earnings season is putting on a dramatic "tale of two extremes." Dell's earnings are exploding thanks to AI servers, while retail giant Costco is sounding the alarm, giving us a crystal-clear picture of the current US economy. **Body:** Last night's earnings season was basically a massive "split personality" show! 🎭 On one side, we have a carnival for tech hardware; on the other, a sigh of despair for physical retail consumption. 🔥 **Dell: The "Pick-and-Shovel" Seller of the AI Era** Dell's stock price skyrocketed after hours, and the reason is simple—AI servers are on absolute fire! The earnings report showed that revenue from this related business beat market expectations by a whopping **26%**! What does this tell us? It proves that no matter the macroeconomic climate, big tech companies aren't saving a single penny when it comes to buying servers for the AI arms race. As long as the AI narrative is alive, "pick-and-shovel" sellers like Dell are going to be raking in the dough. 💰 🛒 **Costco: Is the Middle Class Starting to Clutch Their Wallets?** On the flip side, look at retail giant Costco. Although revenue is still growing, the pace has明显 (significantly) slowed down, and management has become cautious about future consumer expectations. This is the ultimate bellwether for US consumption! If even the middle class—who love hoarding bulk goods the most—are starting to pinch pennies, it shows that the pressure of high inflation and high interest rates has started to seep into ordinary people's dinner tables and shopping carts. 😟 **To sum it up:** The current market logic is absolutely brutal—if you're linked to AI, you're the king; if you're purely in consumption, you're at the mercy of the market.
