An explanation of the apparent anomaly of a "rising market 

 on increasing stocks" is afforded by the changed attitude of deal- 

 ers. Under the auction system, before the war, rubber was 

 constantly coming into the market in unlimited quantities to be 

 sold at any price the dealer chose to give. The effect of this was 

 to make persistent bears of the dealers who were interested in 

 getting the rubber at lowest figures for subsequent re-sale to 

 consumers at a profit. The war changed things. The embargo 

 on exports, delays and uncertainties in transportation and deliv- 

 ery, so interfered with supplies that the dealers became interested 

 in obtaining better prices for the stocks on hand, and from bears 

 were transformed into bulls.
