Reprint from 4/27/07. The rest of the world has a head start on what may happen tomorrow (from examining the declines in foreign markets today). I thought this might be informative to those that missed it.The "Dow Jones Industrial Average" sounds impressive. Right now it’s at 13,000. Add up the value of all thirty stocks in the DOW and you get $1,600. Hmmm, where does the 13,000 come from?
There is the Dow divisor index which is currently at 0.1248. It is a peculiar animal. Here is a cut and paste from Wikipedia
Assume an index comprising on 2 stocks A and B.
A is priced at $100 and B is priced at $200.
Hence the index value in this case is (100+200)/2=150
(where N=2 which is index divisor). So the index value here is 150.
Now assume stock B undergoes 2:1 stock split so its value becomes $100.
Now the index value would become 100 instead of 150.
To correct his irregularity we need to do the index divisor calculation as
(100+100)/N=150 (Since Market Capitalization of the stock is unchanged).
Hence, upon calculation we get the value of N as 1.333.
This shows that a stock split caused the index divisor to be revised
from a value of 2 to 1.33.
Today with the DOW, you would take 1600/.1248=12,820

If you examine the Market Weighted %, this is the actual amount the Dow swings per dollar for each individual stock. Notice that a 5 dollar move in IBM translates into 30 points on the DOW (5 x 5.92). A 5 dollar move in Intel translates into 7 points on the DOW (5 x 1.38).
As boring as all of this is, its rather like doing 20 miles per hour in a car and the Manufacturer decides to add another zero to the speedometer and make it 200. In that scenario, you can go through a hospital zone at 200 mph and not suck the drapes out of the rooms.
DOW 13,000 sounds super, but when you add it up you begin to realize that the perspective is a little misleading. The DJIA 30 stocks are worth $1600. The real validity of the DOW hitting 13,000 has more to do with someone who bought into the market in about the year 1910.
The next picture is a logarithmic rendering of the DJIA over the last 100 years. The slope of the graph is linear. On logarithmic paper that's not a good thing. It could indicate a bubble, or the last step before hyperinflation (slope equals inflation rate). (Click on the graph for a larger picture)

The area under the graph line could be considered the measure of value paid for all stocks in the market. For that reason I have included the next graph which is linear. The crash of 1929 and 1987 are not very noticeable. This one, puts in perspective the large amount of money moving into the market. (Click for a larger picture)

The DJIA broke through 13,000 today or $1,600 (if you do the math my way). Both graphs tells a story. One is logarithmic because it was too big to fit on a page without losing detail. The other suggests that 1929 and 1987 were non events (that should raise an eyebrow or two).
On the positive side, the Dow's a lot more liquid than the housing market. Stockmarkets are not sticky on the down side! At one time Wall Street offered "Cradle to Grave Service." There was a nursery at one end of the street and a grave yard at the other. The grave yard is still there.
