It sure would be an interesting world if the SEC decided to require COLA (Cost Of Living Allowance/Adjustments) towards the purchase of stocks... Until then, the Stock Market is as it is...I don't see how a future 3-28-2028 stock market valuation which is not adjusted so is apples to apples 3-28-2025 values. Not even sure a stock index is the measure to show whether your neighbors are better off in 36 months than today. Not everyone owns stocks. Or a house. Or a car. We all eat, though.
How about we bet on whether the price of a basket of groceries over these 36 months will go up more as a percentage than wages go up over the same 36 months? No need to adjust since are looking at growth or decline rather than absolute dollar change.
