Coming back to Aus trading, I have come to the point of sorting out liquid option series.
This involved the labourious process of finding the total open interest in each of the option series as the quick and dirty guide to option liquidity.
FYI these are the series with OI > 20,000
bhp 180000
xjo 165000
nws 83000
cba 76000
rio 76000
nab 75000
wbc 73000
anz 60000
qan 60000
osh 55000
amp 53000
lhg 50000
bsl 47000
mig 39000
iag 38000
awc 36000
fgl 36000
wpl 35000
wow 30000
amc 25000
mbl 25000
sgb 22000
cml 22000
rin 21000
sto 21000
map 20000
ncm 20000
Firstly, any of you option traders have further comments to this list? Any symbols that should be scrapped for reasons that are not obvious etc?
Secondly, I have noticed something serious. Most of the OI is in the OTM options, with almost zero OI in the ITM options of the less liquid series.
What is that? Doesn't anyone trade ITM options? It is no wonder most expire worthless.
I'm used to heaps of liquidity and OI right down, way deep into the money. Any comments here?
Cheers
