Also I think the stock market is likely overvalued, probably because so many retirement programs are now just funneling money into the stock market which inflates stock prices.
Also the way we calculate net worth by multiplying the last share price times total number of shares likely vastly overestimates the value of a company. If large numbers of shares were sold the price per share would almost certainly fall.
@alienghic @rbreich but they're not sold all at once, for that very reason. They're sold in controlled small batches.
