What the H*ck Is Factor Investing?

The video introduces factor investing as a middle ground between pure indexing and active stock picking, offering a systematic, rules‑based approach to capture long‑term outperformance. It explains that factor investing starts by asking which characteristics have historically driven stock returns, such as value, size, momentum, profitability, and low volatility. These characteristics, called factors, must be grounded in economic or behavioral theory rather than mere statistical coincidence. The presenter emphasizes that factor strategies are not random data mining, noting the mantra "What has driven stock returns historically?" and warning against "second‑guessing" individual companies. He points to the channel’s library of videos as a practical guide for newcomers. For investors, the approach promises excess returns with less research effort, making sophisticated, evidence‑based investing accessible to retail portfolios and potentially reshaping asset allocation decisions.
