Diversification

A sector is a broad group of stocks, often in one industry (e.g., healthcare, technology). An industry is a more specific group of companies within a sector. An index (e.g., S&P 500, Dow Jones Industrial Average) reports changes in a specific sector or the economy, measuring company performance compared to others.

Mutual funds pool money from many investors to invest in a diversified portfolio of stocks, bonds, or other securities.
