tastyworks has a wide range of securities for investors to choose from. However, it might be argued that it is narrow rather than broad. It may be less than desirable for some investors, notably many conventional long-term buy-and-hold types. Due to the broker's lack of services in critical sectors like bonds and mutual funds, this is the case. It's not simply that tastyworks does not provide any no-transaction-fee mutual funds — there are no mutual funds at all! Bonds are the same. Preferred stocks, another popular choice of income investors, are also no longer available.
