Comment: Unclear, depends on liquidity of the underlying investment. Also, even if illiquid, unclear why ‘overvaluation’ would persist.
Question B: Rebalancing of investors' portfolios to make room for SpaceX will cause measurable price pressure on other large growth or technology stocks in the days after the IPO.

Comment: If the outcomes are fairly idiosyncratic and unrelated to aggregate conditions, then this is true assuming prediction markers are fairly liquid and free of manipulation. If the outcomes are related to macro conditions, then prices of these contracts may embed a risk adjustment
Question B: Retail market participants would be measurably better off if sports contracts on prediction markets were regulated more like gambling than like financial derivatives.

Question A: Nasdaq has been consulting on inclusion of the largest companies in its indexes: https://indexes.nasdaqomx.com/docs/NDX_Consultation-February_2026.pdf

Changing the rules for index inclusion to allow fast-track entry by extremely large IPOs (including waiving the free float requirement) is consistent with the objectives of passive index-based investing.

Private Credit Funds

Question A:

Some major private credit funds - including those offered by BlackRock, Cliffwater and Morgan Stanley - have maintained their redemption limits, not fully filling all investor requests.

The enforcement of restrictions on withdrawals from private credit funds predicts that the funds will substantially underperform indices of liquid high-yield corporate bonds over the next 18 months.

Comment: private credit assets are illiquid so how they are valued matters. Capping redemptions prevents a bank run, but we do not know if the underlying issue is a liquidity or solvency problem. I suspect the latter but we do not have the underlying data.
Question B: Assets in the private credit funds that are restricting withdrawals are substantially overvalued relative to their true market value.

Comment: Assuming the definition of market value includes the illiquidity discount, then the statement is probably true: if funds could sell the assets close to their internal valuations then there would be no need to cap redemptions.
Interest-bearing stablecoins, either via direct issuer payments or exchange-provided rewards, would measurably erode the deposit franchise of banks in developed-market economies.

Housing Affordability

Question A: Having the government-sponsored housing agencies Fannie Mae and Freddie Mac buy $200 billion in mortgage-backed securities would reduce mortgage rates by more than 25 basis points.

Comment: It depends on the slope of the demand curve for buying MBS. I do not know what is the size of the purchase needed to move spreads by 25bps.

Comment: Institutional investors own fewer than 1 percent of family homes. Maybe there is some heterogeneity, but the overall effect should be small.
