Investing Vocabulary, Without the Mystery

Stocks, bonds, funds, and the handful of words that unlock every article.

Risk and return travel together, always. Higher possible growth means bigger possible drops; anyone offering high return with no risk is describing something that doesn't exist (the SEC's investor.gov keeps a museum of what those pitches actually were).
