Buying a particular stallion in numbers like Savabeel purely playing the numbers , the colts syndicate is one syndicate of owners working on one winning "The stallion making race 2000gns " or a G1 race of some description , selling that one horse makes the profit for the whole syndicate , get 2 or more and your quids in .
Sangster and his mob started this in the 70/80s , buying everything no matter the price and reap the rewards selling as stallions , some at huge prices , some at not so huge , but at the end of the season it was about profit .
If nothing works then the tax write off covers the losses .
