About Us

Market Cycle Dynamics (MCD) was created to research and track global market cycles in price, time and sentiment, and publish The International Market Cycle Dynamics Letter and the Interim Briefing. The Market Cycle Dynamics (MCD) approach and method of market cycle analysis provides a “formula timing plan”. The goal is to provide market cycle turning point analysis for individual and professional investors and traders who make their own informed investment decisions.

David Knox Barker is the founder of Market Cycle Dynamics, LLC, and the publisher and editor of The International Market Cycle Dynamics Letter. Barker is one of the world’s foremost experts on market cycles, the economic long wave of innovation, and Fibonacci based market analysis. He is author of The K Wave (1995, 2012 eBook), also published as Jubilee on Wall Street (1987, 2009). He is currently “2020” working on a 5th edition with the working title of Market Cycle Dynamics; The New Science of Cycles. He is a writer, entrepreneur and technical market analyst. He has researched stock market cycles and written on the impact of the long wave on international financial markets and the international political economy for over 30 years. Barker developed the powerful Market Cycle Dynamics Formula Timing Plan approach to market cycle analysis based on decades of market cycle research in price, time and sentiment. Barker also discovered a unique Fibonacci grid drill-down method that works in any market to uncover multiple levels of nested Fibonacci grids within grids for identification of cycle pivot points in long and short cycles. Barker has been on a public writer’s strike regarding market cycles since 2012, due to central banks not being forthcoming and greatly distorting the pricing mechanism of markets for all market analyst. He last spoke publicly on the K Wave to the Computerized Special Interest Group at MIT in 2013. He has not actively promoted MCD since 2012. He now only expresses his view on market cycles in the International Market Cycle Dynamics Letter for his loyal MCD subscribers, some that have been reading his market cycle musings since the 1980s. He has continued writing and publishing the letter, since he thoroughly enjoys it, and believes there is important undiscovered science in the cycles of human activity.
