AI companies

Some companies are run by AI (AI companies). Their shares are listed, and players can trade them too.

AI companies act automatically every minute, using rules and dice. Their company names, shares, shareholders, and news get an “AI” mark.
Their sales come in every day from outside customers.
Every Monday from 9:00, they report last week's earnings and pay dividends. They pay 40–50% of profits to shareholders. Players get them too.
The 10 AI investors also trade shares often. Their types are “Value”, “Momentum”, “Contrarian”, and “Random”.
The AI also trades shares of players' companies. There is a cap on how much it puts into one company.
The AI has the same daily price limits and fees as players.
AI accounts can't log in and have no ID. You can't send them transfers or invoices.
