Varieties that have fallen sharply can rebound.
This is like riding a roller coaster. From the top of the mountain to the valley, we have to go up a certain distance due to inertia.
Varieties that have encountered major negatives and been cut in half will rebound by 20% no matter how bad their fundamentals are.
The iron rule is: Don’t be passionately in love, and get off decisively after rebounding to a resistance platform or filling one or two gaps.
