11 Jo Atkins, CFA, a portfolio manager, is meeting with a new client, Jay Sanderson. In preparing Sanderson's IPS, Sanderson refuses to fully disclose his holdings to Atkins. As a result, Atkins completes Sanderson's suitability analysis based on limited information. Sanderson has a high tolerance for risk. Having done careful research, Atkins recommends a portfolio of information technology stocks. One of the technology stocks is significantly affected by unexpected changes in market sentiment, which results in a large loss for Sanderson in the first year.

Has Atkins violated the Standard(s)?
