Proprietary Data: Never Available to the Market Before Now

Core Earnings: New Data & Evidence, a new paper in The Journal of Financial Economics, unequivocally proves that the market does not impound the earnings impact of our proprietary analysis of footnotes disclosures.

Professors from Harvard Business School (Charles Wang and Ethan Rouen) and MIT Sloan (Eric So) wrote the paper. Here are a few quotes:

“market participants are inefficient in impounding the implications of non-core earnings, especially those stemming from the footnotes of the 10-K, into stock prices.” – pp. 34, 3rd para.

“Core Earnings contains information about future performance that is incremental to Street Earnings” – pp. 29, 2nd para.

  1. Generate significant, scalable and idiosyncratic alpha, and
  2. are based on proprietary data.
