Seems we've had the same experiences .. because I never was in a stock that reversed-split and it didn't tank afterwards. People say .. the market cap doesn't change .. true .. but it does when it tanks subsequent to a reverse split to desperately stay on an exchange.
The only thing I would say where a reverse split would be beneficial is to get the dollar pps value over a specific price for funds to buy. Many of these investment houses have charters, which don't allow a purchase if the stock pps is under a specific dollar price.
