Major indexes like the S&P 500 are typically quoted as price-return only, excluding dividends. This means investors and the financial press are constantly looking at the wrong number, systematically understating true market performance. This leads to more negative sentiment on high-dividend days and flawed evaluations of fund performance, skewing perception and capital allocation.

Conventional wisdom blames high fees and a "paradox of skill" for active management's failure. However, fees are at historic lows and increased manager skill should theoretically reduce market volatility. The fact that managers are performing worse despite these tailwinds indicates a deeper, structural market shift is the true cause.

The rush of investors buying stocks specifically to receive a dividend creates a price run-up in the week or two before the ex-dividend date. After the date passes, this demand evaporates, leading to a predictable price reversal over the following six weeks. This cycle creates a constant and exploitable price pressure effect on dividend-paying stocks.

Momentum investor Gerald Tsai's strategy made him a star, attracting huge inflows. Even after his performance collapsed, placing 299th out of 305 funds, assets continued to grow due to his past reputation. This highlights the misaligned incentives of AUM-based fees, where managers can profit long after their strategy fails.

The market for all-in-one asset allocation funds remains saturated with expensive, tax-inefficient mutual funds despite superior low-cost ETFs. The transition is slow because incumbent firms rely on investor inertia—the "death, divorce, or drawdowns" events that trigger portfolio reviews—to keep assets in legacy products, delaying an inevitable shift to more efficient solutions.

Contrary to classic theory, markets may be growing less efficient. This is driven not only by passive indexing but also by a structural shift in active management towards short-term, quantitative strategies that prioritize immediate price movements over long-term fundamental value.

A significant portion of investors view dividends as extra income separate from a stock's price. They don't grasp that the share price mechanically drops by the dividend amount, meaning they are not wealthier. This fundamental misunderstanding, the 'free dividends fallacy,' has major downstream consequences for their investment strategy and spending habits.

During periods of low interest rates, investors flock to dividend stocks seeking income. This concentrated buying pressure inflates their valuations relative to fundamentals. Investors who buy during these waves of high demand are purchasing at inflated prices, setting themselves up for significant underperformance when the trend inevitably reverses.

So-called passive indexes have a small but impactful "active side" in their turnover. This component behaves like a flawed momentum strategy, forcing the index to systematically buy stocks after they've surged and sell them after they've plummeted, creating a performance drag.
