Jim; Thanks for the encouragement, I have got a brain teaser right
now that has me stumped.
I'm running two programs that track the DJI, one is price weighted
like the DJI index, the other I set up as Market cap, also know as Market value weighted ( like the S&P ).
The teaser is in the market cap one.
If I take the Total market cap of the DJI X the average price per
share I get almost 16.8B more as market cap value,
Than if I take the individual issues shares X price and sum them
up.
I found this once before and gave up trying to figure it out
the average price x total shares should equal the same total
market value, as the share price x shares of the stocks and
summed.
I wonder if this is an anomaly in the way Msft does the math,
after all it's about 2.375 T to 2.359 T, or .71% it don't
make sense.
------------------
That aside ;
The price weighted one vs the cap weighted one make an interesting
comparison. They can and do at times move in opposite directions,
It's my idea if the Price weighted index out runs the Cap weighted
one to the upside ( rate wise ), the DOW stocks are getting less liquid, and more risky, if it's to the down side, they
they are getting more liquid.
