About us

ZZAlpha serves knowledgeable investors
ZZAlpha LTD. serves professional and institutional investors. We provide portfolios of recommendations exhibiting consistent, high returns with well behaved risk, liquidity and transparency. All recommendations come from the objective and thoroughly tested ZZAlpha® proprietary machine learning techniques.  We supply daily equity long recommendations by subscription for products spanning various liquidity, capitalization, sector and industry segments groups.

Ten years of scientific research
ZZAlpha LTD. was formed in July 2010, after 10 years of scientific research on how equities might be successfully selected by an appropriate machine learning technique.  There are many ways to poorly apply machine learning, parameters, algorithms, and models that produce inconsistent and brittle results.  We investigated (and discarded) many over the years.

Machine learning successfully responds to the unexpected
Machine learning techniques have the ability to learn in dynamic environments and quickly fashion an appropriate response, much as “black-box” auto-pilots on defense and commercial aircraft do when unexpected weather threatens safe landing or critical maneuvers.  Unlike traditional static models, machine learning techniques can respond to unforeseen events.  The ZZAlpha® machine learning techniques learn every night from the market's recent dynamics.

Our machine learning technique evaluates the interconnections, patterns, and changes in the market on a daily basis and places those in the context of historic market behavior, using over half a billion pieces of data and 1.8 trillion calculations every night.

Dominance from scientific methodology
ZZAlpha expects to dominate the field of stock recommendations and stock analysis from machine learning techniques, supplementing and occasionally displacing conventional equity analysis methods for large investment enterprises because of its robust scientific foundation, its breadth across market segments, its consistent, high returns, and its well-behaved risk profiles.

ZZAlpha anticipates extending its effective learning techniques to other major international markets.
