Martin Armstrong

Martin Armstrong is an American self-taught economist and the founder of Armstrong Economics, a firm known for its development of the Economic Confidence Model, which posits that economic cycles occur every 8.6 years, correlating with the mathematical constant π. Armstrong gained prominence for accurately predicting major financial events, including the 1987 stock market crash, but his career was marred by legal troubles; he was convicted of fraud in 2006 and served a five-year sentence before being released in 2011.
