It is appropriate advice for retail investors to tilt their portfolio away from the market portfolio towards factors that have been identified in the academic literature to earn positive abnormal returns relative to the Capital Asset Pricing Model.

Comment: Someone needs to be on the other side though. Hence, it depends on the beliefs, sentiment, risk exposures, and preferences of retail investors to determine their optimal portfolio. There is also implementation risk if ETFs, say, dont closely follow the factors in the literature.

Question A:Stock markets around the world have seen an increasing concentration of trades in or near the closing auction. In the US, for example, about a third of all S&P 500 stock trades are now executed in the final ten minutes of the session, up from 27% in 2021.

Regulator Probes BlackRock and Vanguard Over Huge Stakes in U.S. Banks – The WSJ reports that ‘The FDIC is scrutinizing whether the index-fund giants are sticking to passive roles when it comes to their investments in U.S. banks.’
The exemption of passive asset managers from banking rules - such as needing permission when they acquire shares above the 10% threshold - generates measurable risks to the accomplishment of the FDIC's mission.

On 10 January 2024, the SEC approved spot Bitcoin exchange-traded products:

Comment: It may lower the cost and can broaden access, which may be a good thing for those who'd like exposure to Bitcoin. However, there already are ETFs on futures and, as long as the spot-futures basis is not too extreme, I am unsure the spot ETFs provide a measurable benefit.

https://afajof.org/news/in-memoriam-harry-markowitz-past-president-of-the-american-finance-association-1927-2023/
Application of the principles of modern portfolio theory allows investors in practice to achieve substantial improvements in the risk-expected return trade-off relative to naive strategies such as equal-weighting that do not take account of return covariances.
Vote | Confidence | Median Survey Vote | Median Survey Confidence |
---|---|---|---|
Comment: While it is challenging to estimate covariances and expected returns using historical return data alone, using characteristics helps to outperform the 1/N benchmark (Section 6.1 of the first paper; Table 1 of the second paper; Table 5 of the third paper)

Question A: The Federal Reserve has begun quantitative tightening (QT) to reduce the size of its balance sheet. Fed holdings of Treasury securities have declined by $800 billion relative to the March 2020 peak. The Fed currently holds $4.9 trillion of Treasury securities, significantly larger than the $2.5 trillion holdings prior to the Covid pandemic.
A reduction in Fed holdings of Treasury securities measurably increases the interest rate on long-term U.S. Treasury bonds.

Question A: September 2023 was the 25th anniversary of the collapse of Long-Term Capital Management (LTCM). In response to LTCM's troubles, the Federal Reserve orchestrated a multi-billion dollar rescue package by a consortium of banks and it cut the Federal funds rate target by 75 basis points within six weeks.

Question A: New Money Market Fund (MMF) Rules: The SEC adopted amendments to the MMF rules, including a new mandatory liquidity fee for institutional prime and tax-exempt funds.
