NNDM has been in a parabolic rise recently since September with 3 fractal arc movements within the larger arc reaching its peak. I suspect we should be seeing a retracement in the next few days. The two key fibs to look out for are the .382 and the .618.
Both are valid points of support if the first breaks then the second support will form a stronger support before a return of the price rallying
The .382 sits at 9.52 or in that region
The .618 sits at 6.35 or in that region.
Personally I wouldn't short this stock but would look at re-entries or adds or a new position at the the .382 and .618 fibs
Also the RSI is showing overbought but no sign of divergence.
