Ok Satan, thanks for the advice. So when is a stock not a stock? When it is a cat?
Stocks are not all the same, eventually, they become something that isn't really a stock.
I would have to say that a stock ceases to be a stock when the company behind it goes out of business and liquidates all of their assets. Or perhaps during a merger or acquisition you could say that a particular stock no longer exists and is converted to shares in the new larger company?
It sounds to me like you've been describing shitty stocks. Arguing that the overwhelming majority of the stocks out there are shitty investments because they are overvalued or because they don't pay any dividends would make a lot more sense.
