Excerpts from the book Wealth, War & Wisdom, 2008-Barton Biggs:
“In late 1939, however, well ahead of the Blitzkrieg stock prices began to anticipate the overwhelming victories of 1940.”
“By 1940 and throughout 1941 the German economy was booming from military production. (…) The interesting insight is that by the late fall of 1941, the Berlin market was somehow sensing that Hitler’s luck, his infallibility were fading and that Germany’s military momentum had crested. (…) Did anyone know the tide had turned except the stock market? Certainly a few of the generals suspected.”
