I've done flagged B2B transactions to transfer money INTO public companies from my private companies and have written confirmation from the dev that he's OK with it. It probably helps that all my companies are named similiar and don't change chairman ever.
Well, I guess that makes a good bit of sense. Why would stockholders object to you giving the company money? As long as it was not stolen from a public company it really couldn't be bad... In fact, I wish the transfer money option was available to deposit into public companies you own stock in... Or, possibly some sort of cash advance functionality...
There used to be one, and it's called "issue more shares". Sadly releasing a half-finished function turned out to be a bad idea and so it won't be available until the ask/bid system is complete. Then you'll be able to release more shares and buy them up yourself, that is, until insider trading gets regulated.
But that dilutes the share-base. You are not adding money to the company since you are also increasing the ownership. Each dollar in is, on paper, owned by the shareholder. I'd like a way to add money as an asset. Like a capital injection of sorts... That way each dollar in is an added asset increasing the value of existing shareholder investments and maintaining shareholder power.
All that said I've come to realize this game has absolutely no reason to include a stock market...
The fluidity of the game obsoletes any reason to own stock without exploitable roboinvestors.
A $100m stock investment may yield you $400k in dividends each day... That is shit. I could take 50 million, start a new comp, build a few small stores, stock them, and walk away earning 5m a day AND still have 50m left over from the initial amount. Growing revenue generating assets starting at 5m (easily more) a day or .4m a day in steady income (steady until the dividend is dropped or the company is fucked over or the majority shareholder goes inactive, that is); I know which I want more.
Once the broken rorbocitizens are taken out of the picture you will not see any amazing stock jumps anymore... People will pay what stock is worth(hopefully).
So as an investor there is no good reason to buy stock...
And as a company there is no good reason to issue stock. The small initial IPO gain is not worth the restrictions placed on the company... And without robocitizens no one will buy the stock at over inflated prices from you at a future date, either; so you can't really benefit much as the founder, either.
