In which savings plan is the value of the investment dependent on the performance of the stock market?

The value of the investment in a 401(k) plan or an Individual Retirement Account (IRA) is often dependent on the performance of the Stock Market, especially if the funds are invested in stocks, mutual funds, or ETFs. These retirement savings plans allow for a range of investment options, including equity securities, whose values fluctuate based on market conditions. As a result, the overall return on investment can vary significantly depending on market performance over time.
