Harvard MBA Indicator

The Harvard MBA Indicator is a contrarian, long-term stock-market signal based on the share of Harvard Business School MBA graduates who take “market-sensitive” jobs—roles closely tied to financial markets such as investment banking, securities sales and trading, private equity, venture capital, and leveraged buyouts.

Key takeaways

• The indicator measures the percentage of Harvard MBA graduates entering securities/Wall Street–type roles.
• If more than 30% take such jobs → long-term sell signal.
  If fewer than 10% take such jobs → long-term buy signal.
  Between 10% and 30% is considered neutral.
• It is contrarian: heavy interest in market jobs signals euphoria and potential market tops; weak interest signals pessimism and buying opportunities.
• Historically it has produced more sell than buy signals and has highlighted major market turns (notably signals before 1987, 2000, and 2008 declines).
• This is a long-horizon indicator and should not be used for short-term market timing.

How it works

The premise is simple: graduates’ job choices reflect the relative attractiveness and perceived profitability of Wall Street careers. When many MBA graduates flock to market-sensitive roles, that suggests high expected returns and a crowded market—conditions often preceding market peaks. When few do, it suggests the sector is out of favor and valuations may be attractive for long-term buying.

The indicator is calculated as the percentage of a graduating class taking market-sensitive jobs. Thresholds were defined to produce buy/sell/neutral signals as noted above.

History and notable readings

• The series was compiled and publicized by Roy Soifer, a Harvard MBA, beginning in 2001, though it references historical placement patterns.
• Record high: about 41% entering Wall Street roles in 2008—shortly before the 2008–09 market crash.
• Record low: reported around 1937 when roughly 1% entered Wall Street.
• The indicator hit the long-term “buy” level (under 10%) in 1982, ahead of a prolonged bull market.
• It has historically generated more sell signals than buy signals.

Interpretation and limitations

Strengths:
* Offers a behavioral, supply-side perspective on investor and industry sentiment.
* Useful as a long-term, contrarian gauge rather than a precise timing tool.

Limitations:
* Single-school sample: Harvard MBAs are influential but not fully representative of the entire finance labor pool.
* Structural shifts in finance and graduate career choices (fintech, startups, alternative careers, regulatory changes) can weaken the indicator’s relevance over time.
* Does not provide signal timing or magnitude—only a directional, long-horizon signal.
* Data quality and classification of “market-sensitive” roles can vary year to year.

Conclusion

The Harvard MBA Indicator is an esoteric but historically interesting contrarian measure linking graduate career choices to long-term market sentiment. It can complement other macro and valuation indicators, but should be treated cautiously and not relied on in isolation for investment decisions.
