I think that argument really only applies to new funds into an index mutual fund.

Dale; I guess I'm not explaining what I see, I have that problem,
and have posted the antics of 4 different "types" of indexes,
The DOW, price weighted , S&P Cap weighted ,
Intenut index Dollar weighted; and the SOX equal share weighted,
and they all act differently and also have different divisors.
What I'm trying to say is the S&P is cap weighted..
you can start off with x amount of shares in each one according
to the weighting but if the index changes much, the weighting
changes with it, and while the total outstanding shares don't
change, the amount of shares of each of them you need to hold to
match the index does change. Some how I want to say that's
a result or function of the divisor used to get create the index
in the first place, but I'm not sure that explains it either.
-----------------
I don't have the S&P indexed..guess I could, but I do have the
DOW indexed both price wise like it is, and that tracks it
flawlessly, so I know I got the divisor correct..as a result
if you in the DOW and tracking it, you wind up with the exact
amount of shares of each stock no matter were it goes,
BUT It's a new ball game if you cap weight it.

Note the above, and the below is exactly the same sheet,
Except I will drop the price of GE by $10, note how
the % alocation changes, AND the amount of shares owned
and the amount of money I have in each issue.
The only stock that moved in price was GE..
And droping it may better show the nature of the cap index
and that's what it takes to track a cap weighted index.

Other wise you do not track a market cap weighted index,
I don't want to paste in the whole spread sheet,
But I do know what I'm doing even if I don't explain
it well, Indexes are complex.

Well so is ships stability
and trim calculations, but I can also do them both.
Also I have the only program in the world that in a hand held
old Tandy PC-6 computer will give the exact specifications of all the data in 2 volumes of Petroleum Measurement Tables,
For all the APIs that are in ASTN 1250-80 from volume correction
factors to Density , and I wrote the formulas myself.
---------------
Did it in Lotus 123..then converted that to basic, what a trick,
two volumes with only about 30 lines of code, and I am not a
programmer, & never had one day of schooling about computers.
I also complied it to run on any regular PC.
-------------

After that I wrote the cargo program still in use on the
Tanker Florida Express, it beats the one they paid $10,000
for :-) All they have to do is gauge the tanks, stick in
the temperature , and the API..and it calculates both the
GROSS and NET cargo of all 22 tanks. Plug in the info
in 5 min. and your done, The cargo inspector who does it with
a calculator and the Tables is working for two hours, if he don't
make a mistake he has to track down <G>
