Is Edelweiss entered into uptrend for long term investing??

Almost for the past 3.5 years its been in the down trend from its all time high of 340, went all the way down to around 40.
from there slowly started forming higher highs and higher lows.
at present taking good support at 20 SMA
this could be the best time to enter for long term investing, at least staying in for 1.5 to 2 years to reach the target of 340 (min).
