DECEMBER IN NOVEMBER

Can someone please explain why Tattersalls conduct a February Sale in February, a July Sale in July, three October yearling sales in October and a December Yearling Sale and December Foal Sale in November?
Certainly both the November auctions are part of a series which ends with the December Breeding Stock Sale (November 30 – December 3) and, besides, perhaps one shouldn’t buck tradition when one considers that Tattersalls has been doing business – quite successfully – since 1766.
On the other side of the Atlantic, it was encouraging to see the Keeneland November Breeding Sale – ironically held over 13 days in November – ending on a relatively positive note this week … down just 6.5% on last year’s trade.
