Introduction Financial markets are complex systems influenced by many forces. For decades, investors relied on simplified models to explain why stocks generate different returns. One of the most important breakthroughs in financial economics was the Fama-French Three-Factor Model, which expanded earlier theories by identifying company size and value characteristics as key drivers of performance. However,

Introduction For many years, investors relied on a single framework to explain stock market returns: the Capital Asset Pricing Model (CAPM). According to this model, the expected return of an investment was determined primarily by its exposure to the overall market. However, financial researchers began to notice that real-world markets behaved differently. Certain groups of

Factor Investing For decades, investors believed that stock market returns were mostly driven by broad market exposure. The idea was simple: buy a diversified portfolio, hold it long enough, and the market will reward you. However, financial researchers eventually discovered something surprising. Certain characteristics of stocks consistently generated higher returns over long periods of time.

Dollar Cost Averaging vs Lump Sum Investing One of the most common questions new investors ask is how they should invest their money.

In the world of investing, one timeless principle continues to guide some of the most successful investors in history: Buy assets for less than they are truly worth. This philosophy is known as value investing. Value investing focuses on identifying stocks that the market has temporarily undervalued. These stocks often trade below their intrinsic value

Momentum investing is one of the most widely documented and profitable strategies in finance. Simply put: Stocks that have performed well in the past tend to continue performing well in the near future.Stocks that have performed poorly tend to continue underperforming. This idea challenges traditional finance. The Efficient Market Hypothesis (EMH) claims that past prices

Financial theory tells us that markets are efficient. Prices reflect all available information.Investors act rationally.Abnormal profits should not consistently exist. This idea is the foundation of the Efficient Market Hypothesis (EMH). But when researchers examined real-world data, they discovered something surprising: Markets sometimes behave in predictable, abnormal ways. Certain stocks outperform repeatedly.Some calendar months show
