BIST Portfolio Simulator — Build Your Own Stock Portfolio and Compare with Factor Portfolios
This simulator is for educational and analysis purposes. Not investment advice.
BIST Portfolio Simulator
Build your own stock portfolio with the BorsaFolio Portfolio Simulator and compare its performance against academic factor portfolios. Select any stock on Borsa Istanbul, enter your investment amount, and analyze your portfolio's performance against momentum, value, and low volatility strategies.
Track portfolio weights, daily changes, 21-day and 63-day momentum values. Save your portfolio to monitor its progress over time. Select a start date to compare historical performance and evaluate your strategy against factor portfolio return curves.
What Is the Portfolio Simulator?
The Borsafolio Portfolio Simulator lets you build your own portfolio from 750+ Borsa Istanbul stocks and compare its performance against six academically-grounded factor portfolios: Momentum, Value, Low Volatility, Vol + Trend, Dividend + Quality, and ML Ensemble. Search for stocks, set weights, and instantly see your portfolio's historical return, risk, and Sharpe ratio.
How to Use It
To add a stock, type the ticker or company name in the search box. Set each stock's portfolio weight as a percentage. Once your portfolio is complete, the simulator automatically calculates historical performance: total return, annualized return, maximum drawdown, volatility, and Sharpe ratio. On the same screen, you can compare side-by-side with the BIST 100 index and factor portfolios.
Why Portfolio Simulation Matters
Portfolio simulation is the most effective way to test investment decisions with real data. Backtesting allows you to see how your strategy would have performed across different market conditions — bull and bear markets, crisis periods, high-inflation environments — before committing capital. This reduces emotional decision-making and supports disciplined investing. Academic research consistently shows that systematic portfolio management produces more consistent results than individual stock picking over the long term.
Comparing with Factor Portfolios
The simulator's most powerful feature is comparing your portfolio against Borsafolio's academically-backed factor portfolios. The Momentum portfolio invests in recent top performers, the Value portfolio targets low P/E stocks, and the Low Volatility portfolio selects the least volatile names. By comparing, you can understand which factors your strategy resembles and where you might improve your risk-adjusted returns.
