I suspect that some shareholders with rights entitlements to purchase shares at $9.40 are selling a portion of their holding to pay funds by Bpay to the share registry (these funds must be received by 5.00pm Friday).
This selling pressure will probably end on Wednesday (as insufficient time to move funds around after this day with T+1 and Bpay only clearing overnight).
NBow is probably a good opportunity to buy more RIV at an articially depressed price.
