$MRNA continues to move very well in this pull back but I think it needs to slow down slightly and allow the 50 Day MA to catch up with the strong move.
So a test of the 0.38 Fib and consolidating along this level and confirming that this as a solid support level until the 50 Day MA moves higher would be ideal here to see.
Alternatively, if the price continues to move fast, a retest of the 0.5 Fib would be possible and the price action would meet the 50 Day MA here too, also meeting at a confluence level.
A hold at either level would be an attractive buy to catch Wave 5 higher.
