Serena is based in Singapore and works covering the Singapore market for her U.S. based employer. She is invited to a meeting with the top 20 shareholders of a pharmaceutical company to meet with the management team. During that meeting the finance director mentions that the company will expect its workforce to go on strike next week, which will halt manufacturing and distribution of products. Serena uses this information to update her analyst forecast on the company from a buy to a sell. Please explain which standard is violated.
