I write a blog on politics and the stock market, wallstreetandkstreet.com. I spent over 25 years on Wall Street as a senior equity strategist at PaineWebber and UBS. My reports on thematic investing covered such diverse topics as disinflation, income inequality, benign deflation, the virtues of dividend growth stocks and the threat to job growth posed by healthcare reform. One report was cited in the Republican presidential debates and posted on Senator Tom Coburn's website. For over 20 my monthly forecasts of S&P 500 profits were widely followed globally. During the three years I chaired the committee managing the UBS U.S. Key Call List, it significantly outperformed the S&P 500. Before going to Wall Street I was trained as a professional historian at Princeton (BA) and Harvard (PhD). My first book, A Vigorous Spirit of Enterprise: Merchants and Economic Development in Revolutionary Philadelphia, won the 1987 Bancroft Prize. My second book (co-authored with Jack L. Rivkin), Risk and Reward: Venture Capital and the Making of America’s Great Industries, shows how entrepreneurs in six new industries, ranging from the railroads to biotech, interacted with Wall Street as they were getting off the ground. I have also published seven scholarly articles on various aspects of early American capitalism.
