Mark Cuban does a great job explaining why Wall Street is no longer the economic engine it once was:

Over just the past 5 years, the market has changed. It is getting increasingly difficult to just invest in companies you believe in. Discussion in the market place is not about the performance of specific companies and their returns. Discussion is about macro issues that impact all stocks. And those macro issues impact automated trading decisions, which impact any and every stock that is part of any and every index or ETF.  Combine that with the leverage of derivatives tracking companies,  indexes and other packages or the leveraged ETFs, and individual stocks become pawns in a much bigger game than I feel increasingly less  comfortable playing. It is a game fraught with ever increasing risk.

So back to the original question. What business is Wall Street in ?

Its primary business is no longer creating capital for business. Creating capital for business has to be less than 1pct of the volume on Wall Street in any given period. (I would be curious if anyone out there knows what percentage of transactions actually return money to a company for any reason). It wouldn’t shock me that even in this environment that more money flows from companies to the market in the form of buybacks (which i think are always a mistake), than flows into companies in the form of equity.

He then offers up some ideas about how to return Wall Street to its original role:

My 2 cents is that it is important for this country to push Wall Street back to the business of creating capital for business.  Whether its through a use of taxes on trades(hit every trade on a stock held less than 1 hour with a 10c tax and all these problems go away), or changing the capital gains tax structure so that there is no capital gains tax on any shares of stock (private or public company) held for 1 year or more, and no tax on dividends paid to shareholders who have held stock in the company for more than 5 years.  However we need to do it, we need to get the smart money on Wall Street back to thinking about ways to use their capital to help start and grow companies. That is what will create jobs. That is where we will find the next big thing that will accelerate the world economy.  It won’t come from traders trying to hack the financial system for a few pennies per trade.
