Gee..., such a novel idea. Obviously (but a REAL revelation to those who base their financial planning upon their knee-jerk political views), ANYTHING that you buy with the intention to profitably sell at a later date should be properly timed!
Obviously, I agree with you! There is a time to invest in any asset class and a time to sell. All the protestations via the internet or vocally will not change this fact!
Allocating a portion of one's portfolio to physical gold and gold mining stocks is prudent at anytime. At the present, 15-25% may very well be advisable!
