In
my recent blog post, I found that many stock sectors did not follow the S&P
500 Index to new bull market highs on Thursday. Indeed, of the 17 State Street
"Spyder" ETFs representing various market sectors, only 6 closed at multi-month
highs on Thursday.
The explosion of ETFs has made it easier than
ever to track market themes and regimes, from large cap/mid cap/small cap to
value/growth to the performance of various sectors. I find that tracking the
sector Spyders is a quick and dirty way of staying on top of what is hot and
what is not among stock groups.
Let's, for instance, see which sectors have been
outperforming and underperforming during this recent market rally. We'll look
at percentage changes since August 1, 2006:
| Spyder ETF
Symbol |
Sector |
% Gain Since
August 1st |
| XHB |
Homebuilders |
21.64% |
| XLK |
Technology |
21.36 |
| XLY |
Consumer
Discretionary |
21.17 |
| XRT |
Retail |
19.68 |
| XSD |
Semiconductor |
16.96 |
| XLB |
Materials |
15.79 |
| XME |
Metals and Mining |
13.56 |
| SPY |
S&P 500 Index |
12.50 |
| XLF |
Financial |
11.55 |
| XLI |
Industrial |
11.36 |
| XBI |
Biotech |
9.66 |
| XLU |
Utilities |
8.90 |
| XPH |
Pharmaceuticals |
7.18 |
| XLP |
Consumer Staples |
6.95 |
| XLE |
Energy |
5.16 |
| XLV |
Health Care |
4.80 |
| XES |
Oil and Gas
Equipment/Service |
4.29 |
| XOP |
Oil and Gas
Exploration/Production |
1.66 |
Now here's the interesting thing: Of the seven
sector ETFs that have outperformed the S&P 500 Index (SPY) since August (green
numbers), only one made a new high on Thursday (Consumer Discretionary; XLY).
Five of the ten ETFs that have underperformed SPY since August made new highs on
Thursday.
What does this suggest?
It says to me that this has been a "catchup"
rally, lifting the sectors most hurt in the May-July market drop. The sectors
that were hurt the most in that decline are among those outperforming on this
rally. They were so weak during that May-July period, however, that--even with
recent strong performance--they're not making new highs. In short, what
we're seeing is sector rotation, not a broad rally lifting all sectors to new
highs. That provides a note of caution for those watching only the
large cap indices and tempted to chase the new highs.
