I haven't researched how it impacted individual GM stockholders, but I'm thinking overall it was better for our national economy and way better for the small town main street economy that was/is supported by auto industry dealerships. My City was very worried about both GM and Chrysler Dealerships closing and it would have been devastating.And what about the GM stock holders who were thrown under the bus and were denied historical bankruptcy protections in the process?
I do know 2 things about investing in the stock market: 1. It's a gamble, no guarantees on your investments except for the stock broker profits. 2. Buy low sell high.
