Jack Woodruff, founder and former CIO of Candlestick Capital, joins Kepler CEO Vinoo Ganesh for a 19-minute AI Engineer fireside chat about fundamental investing.

Faster preparation raises everyone’s baseline

  • Woodruff expects AI to change how analysts assemble information while investors still seek a well-supported view that differs from the market’s.
  • He imagines preparation falling from six to eight hours to five minutes; the conversation supplies no measured productivity study.
  • Time saved can fund deeper industry research and calls with people close to a business, as competitors also adopt the tools.
  • Reading filings and understanding companies still matter: summarization reduces preparation without transferring understanding into the investor’s head.

Every number needs an audit trail

  • Woodruff, a former accountant, refuses to accept model-generated figures without tracing their sources.
  • He recalls how a single human data-entry mistake could cost millions, making provenance central to trusting automated financial work.
  • Rechecking every generated figure can consume the time automation appeared to save.
  • He wants proprietary information isolated but defers the security architecture to his CTO.

Use AI to choose where to investigate

  • Screening should identify promising research projects, then direct scarce human attention toward them.
  • Woodruff describes an investment “mosaic”: several independent clues supporting a different view of a business.
  • When every fund has similar tools, advantage depends on questions, proprietary evidence, judgment and speed.
  • He anticipates different team roles, potentially including investigative researchers and data engineers, while admitting the staffing outcome is uncertain.

The headline is a forecast

  • Broader coverage helps only if research quality holds up; Woodruff’s 100-, 200- and 400-stock examples illustrate selection, not tested returns.
  • He distinguishes discretionary fundamental investing from quantitative funds, which have automated trading for decades.
  • His rejection of the fully automated fundamental fund is an opinion about competition, with no head-to-head performance test shown.
  • Ganesh sells software in this market, and the exchange includes a Kepler endorsement.
