yes, but remember he sold some as ser were peaking pre-ionic split which tempered the price of ser and subsequently had an impact on the ser option price post ionic split.
without looking it up the value of the sales in june are about the same as what has just been spent - buying 3 times as many shares as was sold.

why bought we will never know, but it draws a line in the sand that at the time of purchase there is no material announcement to be made.

announcements issued after the market closed, so when it next opens on Monday almost 5 days will have passed since the purchase.

is there sufficient time from oct 8 to oct 12 for a significant event to happen? - I guess it could be so

3 companies that are linked to ser could have a material announcement next week - vxl/ionic/ksn - ksn with drilling to north of myall creek

of course it also increases voting power at next weeks agm - but imo that is a non issue
