Was the market aware that Allco's holdings in the Rubicon trusts of around 10% each are financed by a margin loan?

Checkout the announcement today where they sold a line in RJT as there was a big buyer around, to restore the margin facility back into line.

To me that shows a big reason of selling in the three has been short sellers trying to trigger forced selling in this facility. If the market wasn't aware of this, shouldn't the 3 rally today like afg had that big jump from $2 to $3 when it was discovered a lot of share price weakness was related to margin loan facilities?

Basically the selling has not been on fundamental reasons.
