No i would not because i would know 3 things that happen if i pull that stunt.
1. It becomes public knowledge further decreasing the public trust in said company which leads to more shareholders abandoning ship which leads to me losing more money in the process.
2. On the chance they still pull it off after i sued them to oblivion will result in a bad term relationship between me (the investors) and the company. Which probably will lead to me never been able to work with said company costing me a fortune in the decades to come.
3. If i am an investor and honestly believe that every investment i make will always benefit me or my colleagues i am either a rookie or very naive.
When your investment fails you cut your loses and move on. Anything else will cost you just more money and is not worth the hassle.
You fail to understand the situation here.
1. If you believe the company has broken laws, which it might very well have, you would recoup a lot of that money. Then, yes, you could cut your loses and abandon ship.
2. First, you're going off the assumption that CDPR would simply bounce back. Not necessarily. It's entirely possible they wouldn't and at that point, you'd be the one who got off easy. It's a gamble, like the stock market itself.
Secondly, a bad term relationship? What, you think investors have a close relationship with development teams? Heck no they don't. Most don't even involve themselves in the company. Furthermore, why would you even care if you have a bad relationship with them? They have a fiduciary duty to you no matter how much they hate you. On top of that, they WANT your money. As long as you're not actively trying to screw them over, they can't do nothing. Plus, it might be a good reminder further down the road that they shouldn't mislead their investors.
3. Right, I already touched on that in a previous post. Yeah, the stock market is a gamble from the get go and money can be lost. I've even said that a company can lose all your money and go down under and a lawsuit would be out of the question. The legal reasoning behind this is HOW did they lose your money. There are laws in place. These laws are there to protect the investors. Elon Musk wasn't facing serious legal actions for no reasons after his "joke" tweet about taking the company private. The effects on the market and individuals can be massive.
In this case, CDPR's action do paint a really bad picture.
If your reaction to getting screwed is to cut tail and run, good for you, but that's not how everyone reacts.
