15 Years of Market Experience Turned into Practical Knowledge
My name is Diego Vinicius Righetti Sá, and I have been immersed in the financial markets for more than 15 years. My journey began out of curiosity, following the first news about stocks in Brazil. Over time, that curiosity turned into passion, and passion became a profession. Since then, I have experienced the highs and lows of the markets, faced crises, taken advantage of growth cycles, and gathered lessons that have shaped the way I invest today.
During this period, I have explored both the stock market and the cryptocurrency market—two worlds that may seem distant but share the same essence: both offer unique opportunities for those who study, prepare, and act with discipline.
My background was not built only from books or courses, but from real hours in front of the screen, making decisions, making mistakes, getting things right, and evolving. Over the years, I have accumulated thousands of hours in national and international courses and certifications, always seeking to unite theory and practice.
I specialized in technical and fundamental analysis, but I discovered that the true edge lies in combining traditional knowledge with modern tools. That is why I deepened my studies in quantitative finance, developing mathematical and statistical models to test investment strategies.
I am passionate about turning data into practical decisions. I develop quantitative strategies in Python, focusing on backtesting, factor analysis such as Momentum, and classic valuation models like Bazin and Graham. This quantitative approach was born from the need to eliminate intuition and validate every idea with real data. I do not believe in guesses or shortcuts; I believe in discipline, method, and consistency.
Throughout my journey, I noticed that many investors make the same mistakes I once made. They enter the market unprepared, fall into the trap of easy promises, believe in miracle formulas, and give up after the first losses. My mission is to shorten this learning curve, offering educational content that blends theory and practice, showing what works—and what doesn’t.
My commitment is to total transparency. I do not offer shortcuts or miracle promises. What you will find here is the result of didactic knowledge and real experience, tested strategies, and a continuous pursuit of learning. I believe that financial success is built from the combination of education, discipline, mindset, and method.
If you have come this far, the invitation is simple: explore the content, read the articles, and take part in this journey. The financial market may seem complex at first glance, but with the right knowledge and mindset, it becomes a powerful tool for building wealth.
Welcome. Let’s build a solid and consistent path in the financial markets together.
