Ultimately what caused the tizzy in the markets was the mid-office of financial institutions not being rigorous enough. Not enough backtesting. Inadequate modeling. Weak correlations. Analyzing news, per se, isn't an issue. There are already plenty of data brokers that provide this information (i.e. Thomson Reuters' Guidance, Significant Developments, and many more). Decreasing the latency also isn't an issue. Models that enter runaway states are the issue. Quantitative finance is about rigor -- eliminate the rigor and it's advantages over qualitative strategies are all but gone.
