> Through the first six months of 2025, Apple was the second-worst performer among the Magnificent Seven tech giants, as its shares tumbled 18% through the end of June. That has reversed since then, with the stock soaring 35%, while AI darlings like Meta Platforms Inc. and Microsoft Corp. slid into the red and even Nvidia Corp. underperformed. The S&P 500 Index rose 10% in that time, and the tech-heavy Nasdaq 100 Index gained 13%.

Why do papers do this. I can achieve any numbers by cherry picking the date for the random brownian motion.
