(4)Where any person carrying on a business which consists wholly or partly in dealing in securities, buys or acquires any securities and sells back or retransfers the securities, then, if the result of the transaction is that interest becoming payable in respect of the securities is receivable by him but is not deemed to be his income by reason of the provisions contained in sub-section (1), no account shall be taken of the transaction in computing for any of the purposes of this Act the profits arising from or loss sustained in the business.
