Welcome to Market Cycle Dynamics! The science of cycles for global investors, traders and speculators.

Market Cycle Dynamics drive global financial market trends. The ongoing international crisis of excessive debt, overproduction and price instability is occurring globally and fueling currency wars. The often misunderstood economic long wave cycle is driving the global crisis. The smaller market cycles, including the business cycle and especially the Wall cycle, provide regular opportunities for investors and traders to buy and sell.

Knowing where markets are trading in the cycles in price, time and sentiment reduces risks and improves performance for investors and traders. The MCD Letter also identifies global franchise large capitalization companies that pay dividends and offer discounted value opportunities at Wall cycle lows several times a year.

The International Market Cycle Dynamics Letter provides analysis of the key large and small market cycles. Subscribers in the U.S. and around the world receive the quarterly letter and access to online forecasting tools, and The MCD Interim Briefing Blog, posted when major market moves warrant it.

The K Wave; Profiting from the Cyclical Booms and Busts in the Global Economy, by David Knox Barker, was published in 1995 by McGraw-Hill. The book provided a detailed review of the Kondratieff long wave cycle and the smaller cycles that make up every K Wave. The 2012 eBook edition updated the cycle analysis presented in the book that is now out of print. A new edition is now in the works with the working title of Market Cycle Dynamics; The New Science of Cycles.  The current K Wave that began in 1949 ended in 2020. A new K Wave spring season has begun.

Investors, traders and speculators around the world are discovering the value of Market Cycle Dynamics (MCD) analysis. Visit What Subscribers are Saying for feedback on the market cycle tracking and forecasting found in every quarterly newsletter and monthly briefing.
