Churning
Explanation:
Churning is termed as an act of a broker conducting immoderate trading in the account of client solely to generate commissions. It is an illegal and deceptive practice. It violates security laws. The purchase and subsequent sale of a securities that are little or insignificant to meet the investment goals of client can be the evidence of churning. Consequently it causes considerable losses in client's account or can produce a tax liability.
Churning occurs due to over trading by a broker to generate commissions by buying and selling stocks excessively on the behalf of investor. This often happens when broker has permissive authority over client's account.
