Contrary to popular belief, earnings growth has a very low correlation with decadal stock returns. The primary driver is the change in the valuation multiple (e.g., P/E ratio expansion or contraction). The correlation between 10-year real returns and 10-year valuation changes is a staggering 0.9, while it is tiny for earnings growth.

The 'classic' VC model hunts for unproven talent in niche areas. The now-dominant 'super compounder' model argues the biggest market inefficiency is underestimating the best companies. This justifies investing in obvious winners at any price, believing that outlier returns will cover the high entry cost.

Contrary to popular belief, the market may be getting less efficient. The dominance of indexing, quant funds, and multi-manager pods—all with short time horizons—creates dislocations. This leaves opportunities for long-term investors to buy valuable assets that are neglected because their path to value creation is uncertain.

The primary driver of market fluctuations is the dramatic shift in attitudes toward risk. In good times, investors become risk-tolerant and chase gains ('Risk is my friend'). In bad times, risk aversion dominates ('Get me out at any price'). This emotional pendulum causes security prices to fluctuate far more than their underlying intrinsic values.

Companies like Tesla and Oracle achieve massive valuations not through profits, but by capturing the dominant market story, such as becoming an "AI company." Investors should analyze a company's ability to create and own the next compelling narrative.

The underperformance of active managers in the last decade wasn't just due to the rise of indexing. The historic run of a few mega-cap tech stocks created a market-cap-weighted index that was statistically almost impossible to beat without owning those specific names, leading to lower active share and alpha dispersion.

The most important market shift isn't passive investing; it's the rise of retail traders using low-cost platforms and short-term options. This creates powerful feedback loops as market makers hedge their positions, leading to massive, fundamentals-defying stock swings of 20% or more in a single day.

Financial models struggle to project sustained high growth rates (>30% YoY). Analysts naturally revert to the mean, causing them to undervalue companies that defy this and maintain high growth for years, creating an opportunity for investors who spot this persistence.

The dominance of passive funds and hyper-short-term pod shops has doubled the average stock price movement in the REIT space. This increased volatility creates opportunities for long-term investors to capitalize on exaggerated market reactions to minor news.
