FAQs on Backtesting Mutual Fund Portfolios
Can backtesting predict future performance accurately?
Backtesting can't predict future performance but can provide insights into how a mutual fund might react under similar market conditions.
What is the difference between backtesting and paper trading?
Backtesting uses historical data to simulate performance, while paper trading involves simulating trades in real-time without actual financial risk.
How much historical data should I use for effective backtesting?
Ideally, use data that spans across multiple market cycles (10 years or more) to understand long-term fund performance.
Remember, backtesting is only one part of a broader investment strategy and should be used in conjunction with other analysis methods. Always consult a financial advisor to tailor investment decisions to your personal financial situation.
