A registered representative (RR) has been entering solicited sale orders of XYZ shares with the intent of influencing the market price at the end of the trading day. Which of the following terms best describes the prohibited activity the RR may be engaging in?

Churning involves a registered representative excessively buying and selling securities in a client’s account to generate commissions, regardless of the client’s investment objectives. This term does not apply here, as the RR's actions focus on manipulating the market price rather than generating commissions through excessive trading.

Freeriding is a situation where an investor sells a security before paying for it, relying on the sale proceeds to cover the purchase. This practice does not relate to the RR's activity of influencing market prices at the close of the trading day and is more about settlement issues rather than market manipulation.

Backing away occurs when a market maker fails to honor quotes or withdraws from a market, which can disrupt the trading process. This term does not encompass the RR's behavior of entering orders to influence the closing price of XYZ shares, as it pertains to a market maker's responsibilities rather than a representative's trading practices.
