MRNA is not looking too good.
What we can see is a weekly bearish engulfing candle after clear rejection from the upsloping resistance line. Rejection was nasty therefore we're seeing instant follow through.
You can short it now with a final target at the support which is the entry for longs too.
At the support, flip bullish and take a long position. The target is at the key resistance shown on the chart.
If you short now, pleace a stop loss at 219 - 220 $
Good luck
