Borsafolio Blog is a comprehensive research and education resource for Borsa Istanbul (BIST) investors. Our articles bring together academic factor investing principles, modern portfolio theory, and quantitative analysis of the Turkish stock market. We cover systematic strategies — momentum, value, low volatility, quality, and machine learning — with concrete data and backtest results, making them accessible to both retail and experienced market participants.
In the Investment Basics category we explain foundational concepts such as what a stock is, how the market works, market capitalization, the P/E ratio, Sortino ratio, volatility, and the Sharpe ratio in plain language. The Portfolio Theory & Modern Finance section dives into advanced topics including the Fama-French three and five factor models, Markowitz mean-variance optimization, the efficient frontier, Monte Carlo simulation, and risk parity approaches.
The Turkish Stock Market (BIST) category focuses on the structure of BIST 30, BIST 50, and BIST 100 indices, sector dynamics, dividend policies, foreign investor flows, the impact of CBRT decisions on markets, and unique aspects of Turkish financial markets. Our Crypto & Blockchain section covers Bitcoin, Ethereum and broader crypto markets through fundamental and technical analysis lenses. The Product & Tools category publishes guides on Borsafolio's stock screener, fund screener, BIST radar, diversification score, and portfolio simulator.
Our articles reference leading academics such as Eugene Fama, Kenneth French, Robert Shiller, Narasimhan Jegadeesh, Sheridan Titman, Malcolm Baker, and Jeffrey Wurgler. Every topic is grounded in the unique dynamics of the Turkish stock market, translating abstract theories into concrete examples using BIST-listed stocks. Rather than providing investment advice, we aim to give readers the framework to make informed decisions on their own.
The blog is updated regularly and enriched with monthly reports on our factor portfolios, market analysis, and research notes on BIST stocks. For anyone looking to invest systematically in Borsa Istanbul, this blog serves as a reliable reference in the data-driven decision-making process.
