Reverse Splits

There's no better example than DryShips, Inc. on NASDAQ (DRYS) in 2016 and 2017.

Postscript: DryShips was acquired by an affiliate of the majority owner/founder for $5.25/share on 14-Oct-19. You would have needed over 10 million pre-split shares to receive a measly $5 back (not the best return, despite the 66% premium over-market paid at the time of the acquisition announcement).
