Turn of the market. Wall Street term for the point at which the stock market changes its course.
On the London Stock Exchange the jobber (who is practically a wholesaler) will buy at one price or
will sell at another. The price midway between that at which he will buy and that at which he will sell
— and he will do either — is called the middle price ; the jobber expects to undo or cover his
bargain by a fresh bargain with another jobber at the middle price ; the turn of the market is the
difference between the middle price and the price at which the jobber bought or sold.
