When going clockwise - or forward with time - the hands on a clock go from down to up, they're also going from left to right. (Imagine the second-hand level and on the "9" and going up from the "9" to the "12".)
When the hands on a clock go from up to down, they're going from right to left. (Imagine the second-hand level on the "3" and going down from the "3" to the "6" - the lowest point.)
IOW: to get to the highest point, the second hand must go from left to right; as soon as it stops going to the right, it starts going down and only starts back up as it goes right again.
If the clock is going backwards - or counter-clockwise, then the reverse is true.
THE SAME IS TRUE OF ECONOMIES:
WHEN THEY GO FROM RIGHT TO LEFT, THEY GO DOWN.
WHEN THEY GO FROM LEFT TO RIGHT, THEN THEY GO UP.
