When This Kind of Dog Wins Westminster, the Dow Goes Up
A lesser-known Dog of the Dow.

While many investors have relied on the so-called Dogs of the Dow theory to guide their stock buys, there are other ways to look at canines and equities.

TheStreet's own Jim Cramer has renamed some of his dogs after his favorite stocks, for instance.

With the 2018 Westminster Kennel Club Dog Show starting Monday, Feb. 12 in New York, there is another opportunity to ponder the mysterious links between man's best friend and man's best interests. 

So, here is TheStreet's informal analysis of which breed you should cheer for at Westminster if you're a bull, and which if you're a bear.

First off, it has to be acknowledged that the Terrier group makes up an inordinate number of the winners. In 111 years, a member of the Terrier group has won Westminster 46 times.

Dogs from the Sporting group are next, with 20 wins. Working group dogs have won 15 times; Toys, 11; Non-sporting, 10; Hounds, 6; and Herding dogs, twice.

(If you're doing the math at home, please note that no Westminster winner was named in 1923. On the other hand, it's still more than twice as many data points as the Super Bowl indicator has.)

Here's a look at the Dow's average performance in years when each group won.

As to specific breeds, wire haired Fox terriers have won 14 times, Scottish Terriers 6, English Springer Spaniels 6, and seven other breeds four times each.

But, as one might expect, not all dogs are created equal, at least in their correlations with the stock market. 

For instance, things started out great for wire-haired fox terriers in 1915, when Matford Vic won best in show, and the Dow went up 81.7%. But the next year, when the same dog won again, the index fell a little over 4%. Overall, the Dow has averaged a loss of 4.22% when wire-haired terriers have won. 

Scottish Terriers, on the other hand, have an exemplary record. The breed has won Westminster 8 times and the market has gone up ever single year they've won. Overall, the Dow has gained an average of 17.5% in years when Scottish Terriers won. 

Airedale Terriers also have a perfect record of 4 for 4, but the last one of those to win was in 1933. 

In the post-war years, terriers account for 4 of the 10 worst years for the Dow. But it's a 15-inch Beagle that correlates with the worst decline. In 2008 K-Run's Park Me In First won best in show and the Dow fell 33.8%. 

Perhaps the least auspicious dog for the Dow was a wire-haired fox terrier named Conejo Wycollar Boy who won Westminster twice, in 1917 and 1920, years when the industrial average fell 21.7% and 32.9% respectively, clearly numbers that would leave any investor baying at the moon.
