Ron Peyton argues that implementing high ethical standards in the investment industry is important and beneficial. He outlines principles-based ethics as more effective than rules-based, noting firms should develop ethical guidelines based on principles rather than rules. Peyton recommends regularly reminding professionals about ethics to encourage ethical behavior, and that culture plays a key role by promoting mission and values beyond just financial incentives. Firms should strive to act with integrity to build trust with clients and the public.
