Code to calculate how weekday affects stock price ?

[anhkhoa_lpt]

Dear Sir/Madam,
I come from Vietnam. Iam researching about how weekday affects stock price. I did it for only one serie (code VNI). Now I want expand it to all stock code (near 600 stocks). How can I do that ?
Thanks & Regards,

Code: Select all

'create one serie equals percent of VNI
genr pc_vni=d(vni)/vni(-1)
'create one vector to store results
vector(5) weekdays
'calculate return in weekdays
for !i=2 to 6
smpl if weekday=!i
weekdays(!i-1)=@mean(pc_vni)
next
delete pc_vni
smpl @all

Have you tried searching the forum? There are plenty of examples about that. For instance:
viewtopic.php?f=3&t=9099
viewtopic.php?f=4&t=6612&p=23385
viewtopic.php?f=3&t=10903
And for the batch code, you need to look at the programming examples. A good place to start is:
