We use the geocentric ephemeris, concentrate only on Mercury as it passes through the Zodiac. We mark each day when this planet enters a new sign 80 years ago, i.e. when it arrives at 0 degrees. We also mark those days in which Mercury turns retrograde or direct ... These dates are to be carried over ... exactly 80 years further according to the Sun’s motion and not according to Mercury’s motion ... Each and every one of these positions gave 80 years later tops and bottoms not of a few points but of from 50 to 200 points in hides.[George Bayer (1940): Stock and Commodity Traders´ Hand-Book of Trend Determination.
