Closer To The Internet Of Finance?

In previous posts I have already referred to Emanuel Derman's Blog (one of the most influencing quants, IMO). In his latest post Modern Portfolio Theory And Its Effects On What You Cannot Buy he mentioned a search in prominent sites with financial data.

And some disappointment about the incompleteness of such information, missing practical things, like volatilities of a stock, its correlation with ....

And some surprise that he found a useful set of such information and visualization in Wolfram|Alpha, simply entering the stock symbol. Like AAPL ( equal to Apple stock )

And I think of decision support for global risk management, often requested by regulators. But how to do?

Building an internet-of-finance with massive data management and analytics management on a computational knowledge engine. Wolfram|Alpha.
