MRNA trying to bottom out here

MRNA is bouncing off what use to be its top trend line resistance in 2021.

when a stock is bullish and resistance breaks, that resistance should turn into support when the stock dips again. I believe thats what is happening here on MRNA, also notice how the RSI bounced around this exact area plenty of times this year? my price targets are 355/390 before another pullback.
