If it were, one would take the price of each of the 30 components and divide the sum by 30. That would yield the average price. Since that number would barely move the needle on a day-to-day or minute-by-minute basis, something more was needed to satisfy the voracious appetite of investors. Ergo, the Dow Divisor.
The Dow Divisor is 0.14523396877348. Since it's a fraction of a point, the divisor doesn't actually divide anything. Rather, it's a multiplier, which serves to enhance the gains of the higher-priced stocks and minimize the losses of lower-priced shares. That explains why declines on the Dow are serious events. It's rigged to go higher regardless of volume.
One can clearly see - using such a valuation (weighted) method - why tin-hat theories abound about market manipulation. The Dow leads the market, not only in the US, but around the world. A big move on the Dow triggers the herd instinct to buy other stocks.
Boeing (BA) was the biggest percentage gainer on the day, adding 11.46 points to 371.56. But, thanks to the divisor, Boeing contributed nearly 79 points to the overall Dow gain, despite less than 4.5 million shares changing hands.
By contrast, General Electric was the big loser, dropping 1.16%. But, since GE is the lowest-priced stock on the index, by far, at 13.64, the point loss was a mediocre 0.16. The magic of the divisor meant GE's loss to the overall index was a measly 1.10 points, despite the fact that more than 62 million shares were traded, more than the total number of shares in the three next most-widely traded stocks, Pfizer (PFE), Microsoft (MSFT), and Intel (INTC) combined.
Only four Dow stocks traded lower on the day. In addition to GE, Wal-Mart, Pfizer, and The Travelers finished down, though modestly. Also contributing to the day's massive spike were 3M (MMM), Goldman Sachs (GS), and United Health (UNH), each trading above 200 per share. Their combined advance of 10.77 points were good for another 74 Dow points, despite the fact that they were three of the four least-traded stocks on the exchange (Pfizer was the second least-traded).
So, four low volume stocks were good for 150 points on the Dow. The other 22 gainers were cannon fodder against the bear case as the Dow Industrials outpaced the other indices by a wide margin. The day's gain resulted in the highest closing price on the Dow since March 13.
Happy Dow divisor days!
