All,
I was wondering what comparisons could be made between the IRL Industry Groups, included with R2, and those used by IBD.
I have counted 202 groups in the IRL version, whereas IBD has 197 within its proprietary classification system. After looking them over briefly yesterday, I think they are practically the same. IBD uses 'Medical' whereas IRL says 'Health'; IRL uses 'Bus' whereas IBD says 'Cmml'. For the majority, though, the terminology is exactly the same.
Groups which IRL has but IBD does not have:
Banking - Super Regional
Computers - Educ/Entertain
Computers - Health
Computers - Internet
Bus Services - Temp Help
Groups which IBD has but IRL does not have:
Machinery - Thermal Proc
IRL has two groups: Financl - Pub Fd - U.S. A-M, and Financl - Pub Fd - U.S. N-Z, whereas IBD has one big 395-member group of public mutual fund companies called: Financl - Pub Td Inv.
Just looking at the top three groups performance-wise in Monday's IBD, the groups contain 61, 41, and 14 companies; the analogous IRL groups contain 64, 44, and 14 companies. The presumption is that the companies are mostly the same companies.
So the obvious question is whether the IBD industry list could be used to advantage in scans based on industry groups. Does anyone have any feeling about whether this would be a useful exercise? |
