Boral - Sharp Falls, page-67

Your answer is on the screenshot. Square is Equity index Options. Equity index options are traded on ASX and are cash settled. These are index options like ASX200 options etc.

Circle is single stock options traded on AOM and settle in actual underlying.

Well, looks like today was index options expiry, don't know how that would affect boral.

No bad news but a huge dump. Interesting. Anyone got any other ideas? All because of interest rate rise? Or is housing slowdown in Aus catching up with Boral..
