Questions & Answers

Q: What are stocks and how is their price determined?

Stocks represent partial ownership in a company, and their price is determined by the number of buyers and sellers trading them. If there are more buyers than sellers, the price increases, and vice versa.

Q: What do investors aim to achieve by buying stocks?

Investors aim to make money by purchasing stocks that will increase in value over time. Some aim to grow their money faster than inflation, while others aim to "beat the market" by outperforming the overall performance of all companies' stocks.

Q: What is the difference between active and passive investing?

Active investors believe they can beat the market by selectively choosing specific stocks and timing their trades. Passive investors, on the other hand, believe it is difficult to consistently beat the market and focus on holding a diverse portfolio of stocks for the long term.

Q: What does "beating the market" mean?

"Beating the market" refers to earning a return on an investment that exceeds the performance of a benchmark index, such as the Standard & Poor 500 index, which represents the average performance of 500 large US companies.
