IMO the SP should be north of 9 cents given the ARDS trial success announced 17 July. One seller hurt the price through some clumsy and high volume selling. I think that this anomaly and the option sellers are causing temporary softness which may be short lived.
I pity those who are selling their options at below heads parity now. It is likely to be a compounded loss for them when the SP resumes upward IMO. There is likely to be a significant amount of newsflow before options expiry.
I think those who may be buying/converting the options and flipping heads for a pip or two are equally setting up for missing out when the SP pivots north. I consider that those few players doing this are really giving the opportunity to pass stock to long term investors at a very good price. I see this with stocks often, frequently followed by quick corrections where the underlying value prevails.
