I Love These Companies - But Wouldn't Touch Their Stocks With A 10-Foot Pole

I believe both U.S. refiners (e.g., Valero) and Walmart are fundamentally strong but currently overvalued, offering poor long-term risk/reward. VLO and peers benefit from exceptional refining margins due to geopolitical disruptions, yet current valuations reflect unsustainably high earnings and risk sharp downside if margins normalize. WMT's omni-channel growth, margin expansion, and AI resilience are impressive, but at 38x forward earnings, its stock is priced for perfection with limited yield.
