Believe it or not, the most sophisticated computer “models” running Wall Street are simply Excel spreadsheets. Even the very top firms using more proprietary software cannot cope with the global economy. They lack the depth of models as well a databases. This has always been the specialty of Princeton. Firms have been unwilling to spend the multi-millions it costs to do the real job. We will be fully functioning before year end. This is no small accomplishment. We do not use Excel Spreadsheets. Might as well use stone wheels. It takes a lot more than flat model formulas.
