Good enter point

UNH reached 450 $ recently.
From December 2021 never reached bellow this level. It tried 450 $ six times and bounced back to 550 $. From December 2021 UNH is is swing in a channel between 450 and 550 $.
In weekly chart, it is on 200 days moving average, which seems a very strong support. From December 2021 it always trades above 200 days moving average. In march 2020 it touched the moving average, however, it bounced back and moved higher.
I believe UNH could easily reach 500 $ in near future and 500 $ is not out of reach.
I set my stop loss at 435 $.
Good luck to everybody.
