60/40 Portfolio

The 60/40 portfolio is the simple U.S. equity and bond strategic base discussed in E158.资产配置与有效前沿：去找更好的，更不一样的，更贴近时代的. 运雷 presents it as a starting point for Asset Allocation rather than a final answer: a clear base gives clients understandable exposure before the manager tests whether replacements or additions improve the Efficient Frontier.

In the source, the strategic allocation is roughly U.S. equity and U.S. bond exposure, while a smaller tactical sleeve can express views on rate cuts, factor rotation, small caps, equal-weight exposure, shorter-duration bonds, gold, oil, or other tools.

Key Claims

• Simplicity has product value because clients can understand a stock/bond base more easily than a black-box portfolio.
• Adding commodities, REITs, gold, or other assets should be tested by whether they improve risk and return, not by whether they make the allocation list longer.
• Bond exposure inside a 60/40 base still requires Treasury Duration Risk analysis because short and long maturities behave differently during rate-cut and fiscal-pressure regimes.
• Equity exposure can be refined through Free Cash Flow Indexing or other factor substitutions if they improve expected return without creating unacceptable correlation or concentration risk.

Connections

• S&P 500 — broad U.S. equity benchmark connected to the equity side of the base.
• Treasury Duration Risk, U.S. Treasury, and Federal Reserve — bond-side implementation context.
• Asset Allocation and Efficient Frontier — reason the source starts from a 60/40 base.
• Passive Investing and Investment Risk Management — ordinary implementation and survival discipline.
