How to determine your exit strategy for each stock?

I am just getting back into stock trading and I would like to know how you guys develop your exit strategy for your stocks?

For example I have an enbridge exit for 2028 as a lot of their projects start in 2026 according to morningstar.

I am having trouble with Amd as I either exit at $200 for an easy gain (potentially) or hold until it sees substantial growth by say 2027.
