Key takeaways
- A major wave of IPOs and equity issuance is presented as a typical hallmark of equity bubbles; a resurgence of IPOs in 2026 would be a key signal of a bubble regime.
- It is unclear whether NVIDIA’s AI chip advantage is durable because competitors could hire elite designers and eventually catch up.
- Specialization and concentration are distinct concepts and should not be conflated when evaluating manager performance.
- Liquid private equity is described as useful both for investors who cannot access private equity and for private-equity investors who need a liquid buffer for capital calls.
- Private equity return volatility is materially smoothed because reported marks are based on appraisal-style estimates rather than tradable market-clearing prices.

Ipo Drought Issuance As Bubble Diagnostic And Market Structure Puzzle
- A major wave of IPOs and equity issuance is presented as a typical hallmark of equity bubbles; a resurgence of IPOs in 2026 would be a key signal of a bubble regime.
- Prediction markets were cited as implying a likely pickup in IPO activity, potentially including very large listings such as SpaceX, which could strain index inclusion mechanics for index funds.
- The US equity market was described as being in a massive IPO drought as of March 2026, comparable to the 1970s or 1930s when measured by the share of market value from recent IPOs.
- It is puzzling why equity issuance appears muted now given that similarly overconfident CEOs issued equity aggressively in 1999.
- CEOs are typically unwilling to publicly describe their own stock as overvalued even when they may privately believe it.
- Corporate equity issuance responds strongly to stock price levels rather than contemporaneous business fundamentals, illustrated by GameStop shifting from repurchases to issuance after its price surged sharply.
Ai Macro Impact Vs Equity Cashflow Appropriability And Discount Rate Puzzle
- It is unclear whether NVIDIA’s AI chip advantage is durable because competitors could hire elite designers and eventually catch up.
- A roughly 300 bp rise in the 30-year real TIPS yield since late 2021 would imply a very large equity drawdown under duration-style logic, yet the stock market is substantially higher.
- A breakthrough like ChatGPT should not mechanically imply a stock-market doubling because the gains may be competed away or could destroy incumbent firms.
- Even if AI raises worker productivity broadly, competitive forces may pass much of the benefit to consumers via lower prices, making firm-level profit gains uncertain.
- Shiller’s excess CAPE yield framework evaluates equity valuation by comparing the inverse of CAPE to the real interest rate.
- Large AI-capex decisions by hyperscalers could be a major corporate capital-allocation mistake analogous to a past large-scale tech pivot that failed to pay off.
Extracting Manager Conviction Best Ideas And Career Risk Constraints
- Specialization and concentration are distinct concepts and should not be conflated when evaluating manager performance.
- Given portfolio weights and an estimated covariance matrix, the Black–Litterman reverse-optimization approach can infer the expected returns that would rationalize those chosen weights.
- Cohen says he is running the discussed approach live via managed accounts through a firm he helps called Longwall Investment Partners.
- Using a Black–Litterman reverse-optimization approach, inferred best-idea holdings within mutual fund portfolios outperform other holdings by about 4% per year, with a similar or better out-of-sample result reported using hedge fund data.
- Institutional incentives push many active managers to hold many positions because concentrated portfolios increase the chance of being the worst performer in a period and getting fired despite skill.
- The finding that managers’ top ideas outperform does not imply that managers running highly concentrated portfolios will outperform.
Liquid Private Equity Replication And Adoption Friction
- Liquid private equity is described as useful both for investors who cannot access private equity and for private-equity investors who need a liquid buffer for capital calls.
- Institutional adoption of liquid private equity has been enthusiastic in discussion but slow in commitments because allocators prefer someone else to go first due to career and reputational risk.
- Liquid private equity can be approximated in public markets by replicating PE-like factor/industry tilts and adding modest leverage.
- A liquid private equity replication approach could pair modest leverage with downside hedges such as put spreads to limit crash exposure.
- An alternative to explicit portfolio leverage is to buy highly levered public companies to embed leverage off the investor’s balance sheet, but capacity is limited and many highly levered firms are distressed.
Private Equity Returns Vs Measured Risk
- Private equity return volatility is materially smoothed because reported marks are based on appraisal-style estimates rather than tradable market-clearing prices.
- The typical LBO target profile resembles Fama–French factor characteristics associated with higher expected returns (profitability, value/low multiple, low risk, smaller size, high payout capacity).
- Private equity has delivered roughly 2–4% per year of outperformance versus public markets over the last few decades while reporting significantly lower volatility.
- In Q1 2020 the S&P 500 fell about 20% while private equity reported being down about 10%.
Watchlist
- A major wave of IPOs and equity issuance is presented as a typical hallmark of equity bubbles; a resurgence of IPOs in 2026 would be a key signal of a bubble regime.
- Prediction markets were cited as implying a likely pickup in IPO activity, potentially including very large listings such as SpaceX, which could strain index inclusion mechanics for index funds.
- It is unclear whether NVIDIA’s AI chip advantage is durable because competitors could hire elite designers and eventually catch up.
- Cohen’s 'Five Future Fears' framework prioritizes authoritarianism, fertility decline, China relations, disruptive technologies (especially AI), and the environment as key drivers of whether the developed world worsens over the next decade.
- If the dominant public narrative becomes that AI will take jobs, that narrative shift could itself drive equity prices down through sentiment and behavioral channels.
- Concentrated portfolio strategies may attract lower-quality managers or charlatans relative to other strategies.
- Lamont raises that the approach may overlap with what multi-manager 'pod shops' do internally, and Cohen agrees it probably does.
Unknowns
- How large is the private equity return premium after accounting for fees, leverage, factor exposures, and any valuation unsmoothing?
- What is the magnitude of private equity valuation smoothing when compared with secondary-market discounts and eventual realization values?
- Can a public-market liquid replication approach (tilts plus leverage, potentially plus hedges) match private equity outcomes on a cashflow- and risk-adjusted basis after financing and hedge costs?
- Is the claimed March 2026 IPO drought accurate under consistent definitions that handle SPACs, direct listings, and foreign issuers, and what mechanism explains it if true?
- What explains the asserted puzzle of muted equity issuance relative to 1999 despite high valuations and the incentive for firms to time issuance?
