The best long-term strategy for Kim would likely be:
B. Accept the lump sum payment and invest it in a diversified portfolio.
Here's the reasoning:
- By accepting the lump sum payment of $630,000, Kim can invest that money right away, potentially earning a higher return over time than simply putting it into a savings account or receiving yearly payments.
- A diversified portfolio can provide better growth opportunities compared to the steady, fixed payments of the winnings over 20 years or more conservative investments like bonds.
- Over the long term, the power of compound interest and a well-managed investment can significantly increase the total amount she would have compared to receiving fixed annual payments which might not keep pace with inflation or provide similar investment growth opportunities.
Options A and C involve receiving yearly payments which could result in lower total value over time with most investment accounts yielding higher returns with lump sum investments. Option D (putting it in a savings account) typically offers lower returns than investing in a diversified portfolio.
