The historic rotation out of momentum and into value may signal a major regime change. If cheap AI models boost margins for traditional "value" businesses, it could reverse a two-decade trend of growth stock outperformance for the first time since the dot-com bust.

The quality of public small-cap companies, measured by Return on Invested Capital (ROIC), has plummeted from 7.5% to 3% over 30 years. This degradation means high-growth opportunities now predominantly exist in the later-stage private markets. Institutional investors must shift their asset allocation to venture and growth equity, which has become "the big leagues," not a bespoke asset class.

The dominance of low-cost index funds means active managers cannot compete in liquid, efficient markets. Survival depends on creating strategies in areas Vanguard can't easily replicate, such as illiquid micro-caps, niche geographies, or complex sectors that require specialized data and analysis.

LPs are concentrating capital into a few trusted mega-firms, leading to oversubscribed rounds for top players. Simultaneously, a decline in deal formation and liquidity is causing a potential 30-50% "extinction rate" for smaller, emerging managers who are unable to raise subsequent funds.

With passive investing dominating and market-wide flows unreliable, investors can no longer wait for multiple expansion. The best small-cap investments are companies actively closing their own valuation gaps through significant buybacks, strategic M&A, or other aggressive, shareholder-aligned capital allocation.

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 dominance of passive investing (~65% of the market) and the decline of sell-side research have created a structural inefficiency in small-cap stocks ($500M-$2B). With fewer active managers doing the work, valuations in this segment are extremely attractive, creating significant opportunities for diligent investors.

After years of piling into a few dominant mega-cap tech stocks, large asset managers have reached a point of peak centralization. To generate future growth, they will be forced to allocate capital to different, smaller pockets of the market, potentially signaling a broad market rotation.

While indexing made competition tougher, the true headwind for active managers was the unprecedented, concentrated performance of a few tech giants. Not owning them was statistically devastating, while owning them reduced active share, creating a no-win scenario for many funds.
