"Where there’s a tip, there’s a tap” is an investment adage that means where there is a stock tip, for example, there is a “tap” (someone who hopes to make money off of the tip). The saying has been cited in print since at least 1929 and is popular on the London Stock Exchange.
Despite the simplicity of the financial saying and its age, “where there’s a tip, there’s a tap” is mostly unknown in the United States.

There was an old saying in the London Stock exchange: “Where there’s a tip there’s a tap.” In other words, if someone tells you to buy or sell something he is promoting his own vested interest. It is a pretty good rule of thumb.
