Value Investing is dead unless you understand velocity of change

The fundamental religion of Value Investing is Mean Reversion. The entire strategy relies on the belief that "Price fluctuates more than Value." You buy a beaten-down stock because you believe the market is emotional, and eventually, the price will snap back to the business's "true" steady state. But here is the catch that gets ignored: Mean Reversion only works if the "Velocity of Change" is slow. In Ben Graham’s day, you could buy a boring stock and have 15-20 years to milk the cash flows before the business died. The speed of disruption was physical, it took decades to build new factories or shipping lines. Today, the Velocity of Change isn't just fast; it's growing exponential. Using 50 years of historical data to prove that "Value works" is dangerous because the physics of the market have changed. In an AI world, businesses may not slowly revert to the mean-they may get deleted overnight. Graham’s "margin of safety" doesn't exist when the asset can melt to zero in 18 months (see Chegg). When you buy a "Cheap" stock today, you are essentially betting that the technology disrupting it will fail, or at least happen slower than the market thinks. Look at PayPal (PYPL). On paper, it’s a classic value play. Massive free cash flow, historical low P/E. But the market is pricing it for death because "digital wallets" are being made obsolete by friction-less payments (Apple Pay, etc) and AI agents. If you buy PYPL, you aren't just buying a bargain; you are explicitly betting that the velocity of AI payments is slower than the market expects. Look at Adobe (ADBE). It looks like a fortress with a "moat." But it’s trading at a discount because AI creates a world where you don't need complex editing software, you just need a prompt. The market sees a "Seat License" model collapsing. If you buy it, you are betting that AI video generation won't be good enough to replace human editors for another decade. The Bottom Line: We need to stop analyzing stocks based on simple P/E ratios and "vibes." Too many theses here boil down to: "This looks cheap historically, and I just feel like they'll survive." That isn't a thesis; that's a prayer. In an exponential world, financial metrics are lagging indicators of a world that is disappearing. The "Better Way" isn't staring at a spreadsheet, it's understanding the technology better than the market does. If you can't explain technically why the disruption will fail, the low P/E doesn't matter. You don't have an edge; you just have a bag.
