So you would buy stock with the purpose of discriminating? I think the fact that money is colorblind--pretty much immune to bias--is the best thing about our stock markets.

Then you say 'play' money--is this a stock exchange or a game?

I don't know why I read "ethnic" instead of "ethic". I think "ethical" criteria would've been the correct English.

But again, not everyone's ethics are the same. Killing is a sin, but is killing prisoners? Zygotes? Monogamy vs. polygamy? Communal vs. individual? Stealing vs. taxes?

I think you mean to play a game with pretend companies?

No I thought about real companies and game money. It's not relevant that everyone has a different ethic because the stock price shows the summarization of it. I just want people to buy companies when they think that they have ethic standards and follow them.

I've based lots of my personal investing on supporting companies that manufacture in the USA. To me that's one of my personal ethics--it's also related to my job, as an engineer. Unfortunately, if I'd invested in China or in oil, I might have way-more money when I retire.

Also, investing in US manufacturing means that I sometimes invest in companies that provide military hardware or homeland security-inspections/surveillance. This is a quandary for me because I'm more concerned about creation of a 'Big Brother" or the military industrial complex than most. I can't even keep my own ethics straight--I don't know the game might work.

I suppose if you forget about the complex issues and just equate 'ethics' with those companies that put a leaf in their logo and spout some line about global warming, it becomes simpler. I'm just afraid that death by starvation once the US is broke is much closer than death by hot weather.
