Much like people buy/sell crypto with zero analysis of fundamentals.
I don't think it's a bad decision for Hertz to offer up shares if it allows them to repay a greater percentage of their debt.
I think the real problem is that there are a lot of people who are speculating (gambling) in stocks like Hertz. This has been the case since online brokers came in to existence, and has only been magnified by the recent trends toward $0 fee commission trades pushed by Robinhood and the like.
If there is anything that I'd say needs to change, it would be apps like Robinhood should make detailed company information more easily accessible so people realize Hertz is going to $0 before gambling on a short term swing (which would mean making the UI/UX a bit more clunky + dense, so it probably won't happen)
