With a Series 6 license, the representative is qualified to sell open-end funds, and to sell closed-end funds during the primary offer period. Whether open-end or closed-end, some investment company portfolios establish covered calls to enhance the funds’ overall return. For example, there is a closed-end fund trading under the symbol BXMX, which is an S&P 500 index fund that also engages in covered calls. Back when that fund was first sold to investors, a registered representative with a Series 6 license could have offered and sold shares to customers. And, of course, with a Series 6, the agent is licensed to sell any open-end fund that may engage in options trading in addition to managing the core portfolio of common stock.
