Every ZZAlpha® stock recommendation is now notarized by a trusted third party at the time we e-mail it our subscribers, and is then permanently archived.  That helps assure that our performance and risk information can pass stringent audits. 

ZZAlpha is data driven: we work with objective facts to forecast the price changes and make recommendations, and we work with objective facts to evaluate performance and risk.  We provide transparency of recommendations and results that is seldom found in the investment advice arena. 

ZZAlpha LTD. focuses on stocks with sustained trading volume – it does not recommend penny stocks, micro-capitalization stocks, IPOs, or stocks listed outside NYSE, Amex and NASDAQ.

ZZAlpha LTD. does not handle client funds, does not provide individualized investment advice and does not buy or sell securities.  We receive no compensation from anyone based on which stock we recommend.

Performance measured against benchmarks

The ZZAlpha® machine learning engine has been applied to over 40 market segments, and results evaluated against benchmarks. As the tables below show, in many instances over the 1,3, and 5  year periods, the ZZAlpha® recommendations substantially exceeded their benchmarks.  The results come from recommendations that were certified each morning before market open, to assure they support stringent audit. 

In early Sept. 2014 we incorrectly amended bad data received from one of our suppliers, which caused the machine learning recommendations and results to degrade in several portfolios between then and into 2015.  We have since strengthened validation of incoming data.  None-the-less, our recommendations can never be "corrected" after they are certified and published. The results shown reflect the actual recommendations.  We consider the results for 2015 mediocre.  2016 results were good.

We show here results for portfolios of  5 and 20 equities, recommended daily (i.e.  25 and 100 recommendations a week for each market segment).

Annualized returns for ZZAlpha® recommendation portfolios. Instances where returns exceed benchmark by 200 basis points annualized are highlighted in green. Underperformance of any amount is highlighted in orange.

Notes to tables:
1) Returns are annualized returns, NOT average annual returns.
2) Some benchmarks include dividend reinvestment; others do not.
3) Portfolio returns above show returns AFTER payment of commissions each day.
4) We never use leverage or margin in evaluating results.

Assumptions in performance metrics
The results shown here are produced by a mechanistic trading results simulator used to evaluate all  the ZZAlpha® machine learning engine recommendations.  (The evaluation is entirely distinct from the machine learning technique.) The results shown here DO reflect trading commissions, but NOT spread, limited liquidity, unavailability of short shares, slippage or dividends.  These results assume purchase at a price equal to the reported opening price on the day of recommendation and sale at the reported opening price five trading days later. (Of course, traders often can and do improve on this pricing assumption by scrutinizing the market flow and news at the open or during the day.)

Real market testing
In testing by ZZAlpha employees by actual market trading of various portfolio recommendations for various periods, the actual net returns track the evaluator model  estimates.

Returns of professional traders
The returns shown assume mechanistic purchase at a price equal to the opening price on the day of recommendation and sale at a price equal to the opening price 5 trading days later.  We expect that professional traders watching market movement at open can improve on these returns, or that speculators choosing to sell in a 4 to 10 trading day window after purchase can often sell above the price at open that we assume for closing the position.

Better returns vs larger scale
In general, smaller portfolios have higher (but more volatile) results than larger portfolios.    Please contact sales for detailed information and statistics on portfolios of interest.

* To be conservative, we often use both the selected index and equal weighted population means as benchmarks in our analysis of returns. Returns of equal-weighted population means often exceed capitalization weighted index benchmarks.
