This proposal seems to encourage "pump-and-dump" schemes to an even greater extent. Whoever gets left holding the bag will end up with shares worth negative dollars? We saw last week how bad it is to hold excessively large short positions. This proposal would effectively make long positions have unlimited downside risk as well. I think it would have extremely deleterious effects on investment and the bad actors would still find ways to avoid the downside by leaving other shareholders holding "the bag."
