The Harvard MBA indicator was started and maintained by Roy Soifer, consultant and former HBS student. It represents a long-term stock market indicator that evaluates the percentage of Harvard Business School graduates that accept "market sensitive" jobs in fields such as investment banking, securities sales & trading, private equity and venture capital. If more than 30% of a year's graduating class take jobs in these areas, the Harvard MBA Indicator creates a sell signal for stocks. Conversely, if less than 10% of graduates take jobs in this sector, it represents a long-term buy signal for stocks. In addition, it is also useful to analyse the attractiveness of jobs in finance. Indeed, during the last decade, the indicator has been heavily skewed towards jobs in sectors such as Venture Capital and Private Equity and, in particular after the crisis, Harvard MBA alumni have even further shunned IB and IM.
