$ARK continues to buy a lot of $ACHR over the last few weeks as it had pulled back from $7.50 to $4.70.
I believe this is in its corrective phase right now and this bounce is Wave B, before going lower again to the 0.618 Fib at $4.
$ACHR is a effectively a flying taxi start up and there has been a lot of chat about these companies but I believe the price has run up too early this year, either way, a pull back to the 200 Day MA and the 0.618 Fib for Wave C would make sense later this year.
