What is the last but one sentence of the paragraph?

B. Dabba (box) trading refers to informal trading that takes place outside the purview of the stock exchanges. D. In simple words, it is gambling centred around stock price movements. C. For example, an investor places a bet on a stock at a price point, say ₹1,000 and if the price point rose to ₹1,500, he/she would make a gain of ₹500. E. However, if the price point falls to ₹900, the investor would have to pay the difference to the dabba broker. A. Thus, it could be concluded that the broker’s profit equates the investor’s loss and vice-versa.
