Question on Trading S&P 500 sectors

["Barry Silberman" <barry@xxxxxxxxxxxxxxxxxxxxx>]

Perhaps someone on the list could help with question on trading relative
strength of the different S&P 500 sectors.

General intended approach is to go long strong stocks within strong sectors
and short weak stocks within weak sectors.   However, have found only the
following 6 S&P sectors accounting for only 147 stocks out of 500.

A- S&P Banks Index  (BIX)  (29 companies)
B-  S&P Chemical Index (CEX) (17 companies)
C-  S&P Healthcare Index (HCX) (34 companies)
D- S&P Insurance Index (IUX)  (19 companies)
E- S&P Retail Index (RLX)  (37 companies)
F- S&P Transportation (TRX) (11 companies)

1-  Could someone tell me if there are other S&P sectors that trade which
contain the other 353 companies?

2-  Are there other liquid indexes for EOD stocks you would recommend for
use of this "Top - Down" approach?


Thanks for any insights you can help me with.
