Hi John ; Well back to the Market, and about the S&P Index.
I have said more than once it gets Top heavy, and another reason
just came to me.
First I could see that index funds are forced to buy more and
more of the large caps as it goes up. These become very liquid
and on down turns don't drop as fast or as far.
Only a real melt down would cause them to drop like the smaller
less liquid ones. Hence the way the stocks are weighted and
with so many index funds, the BIG tend to get bigger.
( It may take years but it does set up a huge melt down at some
point in time , as the S&P gets more and more top heavy; just
were the point is that the liquid factor wont work on a down swing
we have no real way of telling until it happens )
--------------------
The new thought that came to me, is the Mergers between BIG
Companies. This also helps or adds to the TOP heavy effect.
In this situation take XON and MOB merging, well the indexers
buy on weight so when you ADD their weight together at first
glance it appears that this will be no more than if you had
were already weighted separately.
However when these two BIG caps become one, it's not the
same to the index as adding the caps together. As now you
wind up with 1 less company in the 500, and another has to
be brought in. No matter how hard they look they won't find
a company to bring into the 500, that has near the cap of
even the smaller of the two big ones that got married

An example would be you have 170 shares of XON , and 42
of MOB, added together you get 212 , the rub is if the new
company coming into the index is smaller than MOB, and
it will just about have to be smaller , as anything near that big
is already in the S&P.
Hence the marriage of two BIG caps adds to effect already in place
of the BIG caps getting bigger by index funds having to buy more
of them. ( some will say they have to sell more, in a down turn
and that is mostly true, but they are easier to sell in a down
swing than smaller less liquid ones so they don't crash as hard
at least up to a point, a point I don't think any one has
figured out.
------------------------------
Now I have talked myself into more work, while I may not can
figure the point out, I should be able to find a way of checking
the relative motion to at least see it when it happens.
Like the if the Big ones do start falling much faster than the
small ones it's melt down time.
