I think you are! ... too late.
I have enough of a gain so that taxes play a role in my decision to hang in there.
I hope it's a small pct. of your holdings.... It could easily zip up 5-10 points (it's thin), but this is a classic case where insiders will (ostensibly, if not altogether truthfully) "diversify" via methodical (and/or disruptive) sales of their pennies-per shares.
I haven't a clue, obviously, as to your other holdings and/or risk tolerance, but I'd say that anything north of 5% of one's funds in "high PE" equities in IKAN borders on insane.
If that's the case, halve your exposure ASAP with the freed-up half going into ATHR.
