Something I been battling- general advice please.

Using Xero as an example... Entry price $30.

Assuming you don’t need to free up cash for something, and you want to stay in the stock as a LT play to 2025-26, is there any point taking profits during your investment period in the stock if:

1. the price doesn’t drop below your entry levels?
2. the price has risen well over $50+ in 2019 and a down trend starts- is it worth locking in profits closer to a high if it means that when you buy back in you’re re-entry price may become 20% higher at $40-50?

Thanks I’m advance.
