I see that in the newest build you renamed the integer number to "Stocks" which I think does reduce confusion a bit. However, I would actually like to propose that you simplify this system even more and only the percentage to players. I haven't reached the late game to know if there is more importance to the integer "Stocks" value, but right now the 2 numbering systems seem redundant and not super reflective of how the stock market actually works.
Whenever you buy shares in a company you are always buying them from someone else. This means that other shareholders stock numbers should decrease proportionally. It's uncommon for a company to release more shares on the market as it dilutes the value of each share (although they do it from time to time). So there is always one specific total number of shares and those are divided between investors. I've noticed that when I buy shares, the other investors number of stocks remains the same instead of decreasing. That gives the appearance that new shares/stocks are just created as I buy them, instead of me buying them from someone else. I suppose in the fiction of the game you could say that I'm buying these shares from outside investors that aren't the companies listed, but I'm not sure if you gain much from that.
It seems the number that players actually care about is the percentage of the company that they own. So why bother exposing an additional number to us that we should keep track of, when it seems to only inform the percentage number? Thoughts?
