Question 1

What is the average stock market return?

Accepted Answer

The S&P 500 has returned an average of about 10% per year before inflation since its inception. After adjusting for inflation (roughly 3% per year), the real return is closer to 7%. However, individual years vary wildly — from drops of over 30% to gains exceeding 30%. The long-term average only materializes over decades, which is why financial advisors recommend staying invested for the long haul rather than trying to time the market.

Question 2

How do investment fees impact my returns?

Accepted Answer

Investment fees compound against you just like returns compound for you. A seemingly small difference of 0.5% in annual fees can cost tens of thousands of dollars over a 30-year investing career. For example, on a $500/month investment earning 7% over 30 years, a 1% expense ratio versus a 0.03% index fund fee would cost you roughly $100,000 in lost growth. This is why low-cost index funds have become so popular — they let you keep more of your returns.

Question 3

What is the difference between active and passive investing?

Accepted Answer

Passive investing means buying index funds or ETFs that track a market index (like the S&P 500) with minimal trading. Active investing involves fund managers or individuals picking stocks and timing trades to try to beat the market. Passive funds typically charge 0.03% to 0.20% in fees, while active funds charge 0.50% to 1.50% or more. Research consistently shows that over 15-year periods, roughly 90% of actively managed funds underperform their benchmark index after fees.

Question 4

Why is diversification important for investors?

Accepted Answer

Diversification means spreading your investments across different asset classes (stocks, bonds, real estate), geographies (US, international, emerging markets), and sectors (tech, healthcare, energy). This reduces the risk of any single investment destroying your portfolio. When one asset class drops, others may hold steady or rise, smoothing your overall returns. A diversified portfolio typically has lower volatility than any single component, helping you stay invested during downturns instead of panic-selling.

Question 5

How does inflation affect my investment returns?

Accepted Answer

Inflation erodes the purchasing power of your money over time. If your investments earn 7% but inflation is 3%, your real return is approximately 4%. This means the dollar amount in your account grows faster than what those dollars can actually buy. Over 20 years at 3% inflation, a dollar today would only buy about 55 cents worth of goods. This is why investing is essential — keeping money in a savings account earning 1% actually loses purchasing power when inflation exceeds that rate.
