Losing Your Shirt

What it is:

Losing your shirt refers to an investment move resulting in a total loss of all financial assets.

How it works/Example:

Meant to imply a degree of loss serious enough to warrant selling the shirt off your back, "losing your shirt" idiomatically expresses the complete loss of financial assets as a result of an unwise investment.

Why it Matters:

Investing in financial assets can involve serious, and for some investors dangerous, levels of risk. It is important for investors to be truthful about the level of risk they can afford to take in order to prevent "losing their shirt."

Best execution refers to the imperative that a broker, market maker, or other agent acting on behalf of an investor is obligated to execute the investor's order in a way that is most advantageous to the investor rather than the agent.
