As you gain more knowledge about investments – for example, how stocks are bought and sold, how much volatility (price change) is usually present, and the difficulty or ease of liquidating an investment – you are likely to consider stock investments to have less risk than you thought before making your first purchase. As a consequence, your anxiety when investing is less intense, even though your risk tolerance remains unchanged because your perception of the risk has evolved.
A market index tracks the performance of a group of stocks, which either represents the market as a whole or a specific sector of the market, like technology or retail companies.

Buy “the basket”: Can’t decide which of the companies in a particular industry will be the long-term winner? Buy ’em all!

This strategy will also help you identify which company is “the one” so you can double down on your position if desired.
