What is the Harvard MBA Indicator?

The Harvard MBA indicator is designed to help individuals evaluate investment market opportunities based on how many Harvard MBA students are working in what are deemed “market-sensitive fields.”

Harvard MBA Indicator

The Harvard MBA indicator is a long-term, contrarian indicator. It provides a calculation of the total number of students graduating from Harvard Business School with an MBA that is entering into working in certain business sectors. The positions include:

When the Harvard MBA indicator reveals that at least 30% of all Harvard business graduates enter the market-sensitive fields mentioned above, a general stock market sell signal is indicated. For example, assume that there’s a flood of Harvard MBAs into the investment banking field. In that case, according to the indicator, the stock market as a whole is in danger of turning bearish.

However, when the percentages of Harvard graduates pursuing such careers fall below 10%, the indicator instead generates a signal that indicates good prospects for a rising stock market.


  •  The Harvard MBA indicator is a long-term, contrarian indicator that calculates how many Harvard Business School graduates are pursuing market-sensitive fields related to finance and trading.
  • If 30% or more of Harvard MBA students are heading into sensitive market positions, the indicator suggests that it is a good time to sell stocks. Conversely, if 10% or less are heading into such positions, the indicator provides an overall buy signal for stocks.
  • The Harvard MBA indicator is esoteric and considered somewhat antiquated; it is typically only used in conjunction with other technical indicators.

History of the Harvard MBA Indicator and How it Functions

In shorthand, the Harvard MBA Indicator is sometimes referred to more simply as the HBS (Harvard Business School) Indicator. The HBS indicator is somewhat esoteric, meaning it’s not really intended to be used by a broad audience but by more specialized traders who understand its significance. Additionally, even traders who use it rarely use it as a sole trading indicator. However, they instead combine it with other indicators used to track the finance and trading industries, such as profit margin and debt-to-equity ratio.

When the Harvard MBA indicator is referred to as long-term and contrarian, the indicator is designed to provide long-term investment signals based on the extent to which Harvard MBA students are attracted to certain positions on Wall Street.

The contrarian piece comes in because the indicator follows an older adage: “The more attracted students are to various positions on Wall Street, the more overbought Wall Street becomes.” It is an indicator that the stock market is saturated and most likely nearing a breaking point. In other words, “when everyone wants in, it’s time to get out.”

The Harvard MBA indicator was launched and operated by a Harvard business school alumnus Roy Soifer, a student who graduated in 1965. The most prominent examples of the indicator functioning with promise came in 1987 and 2000. In both instances, stocks were at high levels, and Wall Street was overloaded with Harvard MBAs. In both cases, the indicator supplied sell signals, indicating stocks were reaching critical levels and were about to tank. In both instances, the indicator was eventually proven correct by a substantial bear market that followed.

Notes About the Harvard MBA Indicator’s Performance

By 2008, the Harvard MBA indicator wasn’t being used as prevalently by market traders. However, history shows us that the indicator provided more than enough evidence that the market was saturated around that time frame and that some form of a bubble was about to burst. At about the time of the housing market crash in the United States, the indicator reached its record high of 41%.

On the opposite end of the spectrum, the record low for the indicator was in 1937. Only about 1% of Harvard MBA students were heading into sensitive market positions, thus indicating it was a great time to start buying stocks.

Soifer, himself, widely stated that the Harvard MBA indicator produces substantially more sell signals than it provides buy signals. The last noteworthy time that the indicator produced a 10% long-term buy signal was in 1982. It proved, however, a sage worthy indicator of the massive bull market in stocks that followed.
