Hooya,
Think about the constituents of both indexes and you will find the answer.
The FTSE250 is much more UK orientated
and cyclical in nature compared to the FTSE100.
FTSE100 is dominated by a very select number of stocks:
Vodafone: £100bn
BPAmoco: £96bn
HSBC: £96bn
GSK: £73bn
RBOS: £49bn
AZN: £44bn
Shell: £36bn
Barclays: £34bn
HBOS: £29bn
LloydsTSB:£26bn
Diageo: £22bn
You will note that there is a
very high exposure to global
businesses and the dollar
(which will lead to reduced
reporting of dollar earnings
when translated into sterling.)
Secondly, they are defensive (earnings) in nature.
Thirdly, both oils and Pharmaceuticals
have been bad performers
(because of the dollar earnings risk?)
So until both sectors gain positive momentum
it will be hard for FTSE to show any performance relative to FTSE250.
