I understand your point, but it speaks of timing the market. No one can do that. No one can know really what price it will be when, that's the point of systemic buying and holding. Selling for profit is trading which is fine if that's your aim, but you don't build wealth by gambling. That's how you lose it. But if you want to build wealth, buy on the way down (price doesn't matter since you are holding, so that means buying it cheap), and then still buy on the way up (because your last purchase was cheap if it is still going up). So I say stop trying to time the market, because it's "time in" the market that counts most.
