Since many brokers disallow investors from shorting sub-$5 stocks, why don't all companies split their stock until it is sub-$5
I do believe it comes down to listing requirements.  That is getting very close to penny stock territory and typical delisting criteria.  I found this answer on Ivestopedia that speaks directly the question of stock price. Another thought is that if everyone were to do it, the rules would change.   The exchanges want to promote price appreciation.  Otherwise, everything trades in a tight band and there is little point to the whole endeavor.  Volatility is another issue that they are concerned about.  At such low stock prices, small changes in stock prices are huge percentage changes.  (As stated in that Ivestopedia answer, $0.10 swing in the price of a $1 stock is a 10% change.) Also, many fraudsters work in the area of penny stocks.  No company wants to be associated with that.
