Herma Koornwinder’s life has been one of reading, reflecting, asking questions, not accepting ‘certainties’ as truths, rejecting, researching, developing, checking and putting knowledge to the test.
      During the 1980s and 1990s, in Holland, she took up subjects of financial research which included the effectiveness of fundamental and technical analysis as applied to the world’s stock markets, the acceleration and slowdown of economies, cyclic waves and economic regularities and their consequences, and trying to find an explanation for apparent random fluctuations in the markets. In this, she was a pioneer in what is now known as analytics - the 'science of analysis' which evolved out of the application of computers to the analysis of databases - and a precursor of 'big data', today's IT term for managing huge collections of information which require traditional data-processing systems to be replaced by 'super-computers'.
      Herma compared and put to the test the ‘vision’ of banks and brokers and some 15 national and international investment journals, and also researched the effectiveness of financial investment software.
      In the course of these studies, Herma discovered the laws and rules of a ‘forcefield’ of underlying energies governing the movement of share prices. Incorporating this knowledge into a model she developed and tested in laboratory conditions at her consultancy, Koornwinder Global Market Navigation (KGMN), she was able to consistently predict, with great accuracy, the rises and falls of stock markets over a period of ten years. During this time, Herma was working for investment and retirement funds, and her analysis in these fields was validated by the accountancy bureau Deloitte & Touche for a five-year period from 1989-94.
      The conclusion of Deloitte & Touche, following their ten-month study, was that out of 23 trend predictions on various stock markets delivered by KGMN over the period 1989-94, 22 were confirmed by later events. Of seven equity portfolios put together by KGMN, six obtained a better result than the corresponding stock market index, and the result of the seventh matched the index. On average, the KGMN portfolios out-performed, in absolute terms, the stock market index by ten per cent.

Professional experience
As one of Holland’s leading global market analysts, Herma gave many interviews and lectures, and was featured in many journals and magazines. She took a stand against the efficient-market hypothesis, modern portfolio theory, and index investments and random dispersion when the risk was not known. She was the initiator of, and advisor to, the KGMN Global Portfolio Fund for private investors.

The whole history of science has been the gradual realization that events do not happen in an arbitrary manner but that they reflect a certain underlying order, which may or may not be divinely inspired.

There’s much to learn from the wisdom and technology of our distant
ancestors that could improve our lives today… Herma Koornwinder is in
the forefront of this new understanding.
