The reason for EGRP down fall had more to do with the weakness of the Nasdaq during that same period falling from about 2575 to under 2400... and nets were especially week during that period. AMTD itself fell from about 109 to 81... so no shock there.
Now if the Nasdaq falls again like that in the next few days (not likely) then your senario could happen, but I doubt it.
More likely in a positive market setting, AMDT will gravitate towards its high of $188 from when the split was initially announced.
Too many good things in the future, especially since the rate hike is behind us.
