Market-timing analyst behind the DeMARK Indicators

Tom DeMark

Thomas R. (Tom) DeMark is an American market-timing analyst and the founder and CEO of DeMARK Analytics, which licenses the DeMARK Indicators including TD Sequential. He began his career more than 50 years ago at a large pension and profit-sharing fund, later held executive roles at Tudor Investment Corporation and with bond manager Van Hoisington, and has been a long-time special advisor to Steven A. Cohen (SAC Capital, now Point72). He has consulted for firms including Goldman Sachs, Soros Fund Management, Steinhardt Partners and IBM.

What they argue

  • Price trends can be timed by objectively anticipating trend exhaustion rather than by following the trend.
  • Market-timing techniques should be mechanical and objective rather than subjective chart reading.
  • A completed price sequence (setup followed by countdown) marks where buying or selling pressure is likely spent.

Books and papers

  • The New Science of Technical Analysis (1994)
  • New Market Timing Techniques: Innovative Studies in Market Rhythm & Price Exhaustion (1997)
