Benefits from a stabilizing economy and improving interest-rate scenario have well positioned the investment management industry, which performed well during the first three months of 2018.After three straight quarters of muted activities, it appeared that volatility was back in the markets in the just-concluded quarter, with extremities in February and March. This resulted in higher trading activities, and increased fixed income and equity revenues, primarily for investment banks.Also, most investment managers have waived off majority of their fees with the rates rising since 2016 and this decline in fee waivers supported their quarterly results. Also, it is expected to continue aiding top-line growth in the upcoming quarters.Notably, as investment brokers earn interest income on un-invested cash in customer accounts, the rate hikes will enable them to invest at higher rates. Thus, brokerage firms will likely engage in more investment activities as rates continue to increase, which will further boost their interest income.Therefore, we are focusing on two investment brokers, TD Ameritrade Holding Corp. AMTD and The Charles Schwab Corp. SCHW, which seem to be well positioned for the future, due to their underlying strength and growth prospects.TD Ameritrade has a market cap of $34.39 billion and provides securities brokerage services and technology-based financial services to retail investors, traders and independent registered investment advisors.
