Investors clearly could do much better if they knew what lies ahead. The stock market, a conclusion coming into being after countless buy or sell activities of investors. but it must conform to the general law of the universe, as investors are part of nature or we called cycle. Importantly, knowing where we currently stand regarding the economic cycle and the market cycle can give us a better idea of what lies ahead. WD Gann Said " If you stand at the right starting point and with the cycle of reappearing history ready, predicting what will happen in 100 years or even 1,000 years can be as easy as predicting that in 1 or 2 years.""There's no better teacher than history in determining the future."Since the 1900's, economists in western countries have engaged in the study the law of the cycle, and all believed that there was a long-term law in the economic growth or recession. There is noting new thing under the sun.In 1930, the American economist S. Kuznets proposed a business cycle applying to housing construction, with an average length of 20 years. This long-term cycle is known as the "Kuznets" cycle or building cycle. C Juglar, a French economist, published his Business Crisis and Cycle in France, Britain, and the United States in 1862. In this book, he pointed out that the capitalist economy fluctuated every nine to ten years, as generally called "Juglar cycle". Joseph Schumpeter took this as the "medium-term cycle", or the "Juglar cycle". All research prove the economic cycle is existing. In the last few years, I used the name of "SiuLung" to publish my prediction. In Chinese, 'Siu' stands for little and "Lung" stands for dragon. So "Siulung" means modest but powerful and lofty aspirations.After reading this book, you will understand the power of cycle, Gann, Financial Astrology and Siulung's Gann Reversal Day.
