This old song? That share prices reflect something other than the "intrinsic value" of a company is well documented in over 300-years of history starting with the Mississippi Bubble and most recently the COVID crash. https://twitter.com/SenWarren/status/1355187260514250754

Position sizing, checks from the Gov't to individuals, Fed, social media, animal spirits all play their part in moving price away from intrinsic value....always have and always will.

Not to belabor a point, BUT....when the value of a stock rises it almost ALWAYS benefits the employees of the firm in that it allows capital raises ($AMC), reduces debt ratios to allow additional debt financing, all of which tend to keep their employees employed.
