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.
