Somewhat like the drug selling system, although the same table will be accessible from each city. Whew okay. This is probably going to be a butt to code and all that, but I think it could have some really cool effects on our world. 

Creating a stock: Individual must register for a ticker symbol (ABRV), pay some sort of high fee for this, and create this company profile. This could potentially be incorporated into an almost crew display-like system in which there is a registered CEO,CFO, COO, and so on. The stock market stuff would be under a separate drop down option under the profit tab and under the drug selling option (there's a big space there). 

The stock market could potentially include some NPC type stocks to start, but as more companies (possibly derived from RP'd businesses) are added by players, the opportunities are pretty endless. Companies will have to include how many stocks are available, and their start asking price. These two numbers will change how much their initial fee is to create the company's name on the registry. 

The problem I easily foresee is determining how these stocks will change over time, whether they naturally appreciate or if it is determined by player investment. Additionally, figuring out some of these rates will be annoying. 

But looking on the 'bright' side, a lot of white crime is possible (Hey this is a mafia site, right?). Insider trading, hostile takeovers, dealings with monopolies and other stuffs. This definitely develops our commercial enterprises, I know we all love business district businesses but they don't really make you any money. Also, it can fit with the great depression in that it's easily match-able with U.S. history to explain why no stocks have existed before (in our history). To begin, it will probably need a lot of bug testing and admin oversight but it could be really cool.

This gets a massive +1 from me, Brilliant idea. I dont know how it can be incorporated, or if it needs some tweaking but this is such a great idea :)

Honestly, I've seen the stock market idea proposed a lot over the years. But I like Arturo's suggestion, and I'd add the following: let's add a stock market and make it a mini-game like the Durden raid. 

Each crew (or each Made Man+) (maybe each Boss+?) can create a "company" and they can upgrade facilities, upgrade NPCs (hire better security, hire better finance guys, hire better marketing team, etc.)

I would love to see stocks linked to the business district, but if that's too hard or could open up the potential for abuse, perhaps a disconnected mini game could be launch soon. 

As Gavin as said seen this many times, I'm for it, be nice to add something into rotation of clicks

I also like the business district tie in, but we can RP that if like Gavin suggested, only certain members of a crew can take care of it. Boss would make more sense, maybe even Consigliere, as this would need to be someone proficient in business and also trusted. Then we can simply write the tie in to stocks and the businesses.

Ah. I'm all for this btw. 

Giving this a sly bump

Bump all the way!
