PuzzlingAll of a sudden the volume of CRH jumped from 450k to 700k without a dent in the price. What is going on? My guess is there are inter-house deals, one investor transfers his shares to another who are in the same investment house. i have no other explanation because if the transaction was in the open market it would definitely affect the price of the stock. But with an arrangement like this, not a dent to the price.
