There is no denying that the MM will manipulate warrant prices whaen they can but I would also agree with the point cpecan has made - that if you trade warrants that have a reasonable amount of time before expiry and are not to far out of the money they will behave fairly predictable.
CBAWOM being over $4.00 out off the money with only 6 weeks before expiry and being priced at around 1/2 a cent is not a good combination. Throw into this non MM bids higher or offers lower than the price matrix and it all makes for a very risky trade.
This also highlights another problem currently being the lack of warrants avaliable for example over half the NCP call warrants avaliable expire in November.
