If held for a long time, will adding at a low point have a better effect?

As soon as you buy, it drops; as soon as you sell, it rises
An unchanging law of the market
This week is tougher than expected
Planning to adopt a three-horse carriage strategy
I will hold these three long-term
I will not adjust my positions again
Holding until the peak of next year's bull market
The next step will only be to liquidate
I will not make any portfolio changes
