Summary
Top1000funds.com published a piece headlined "CalSTRS CIO: The old portfolio playbook is finished," in which the chief investment officer of the California State Teachers' Retirement System (CalSTRS) contends that the approach institutional investors used over the past three decades no longer fits current conditions. The headline frames the argument as a broad challenge to conventional portfolio construction rather than a narrow tactical call.

The available source text is limited to the publisher's summary and boilerplate describing Top1000funds.com, which covers governance, portfolio construction, efficient portfolio management, fees and costs, and sustainable investing for large institutional investors across more than 40 countries. The publication's stated editorial position is that the industry should test whether existing processes for handling risks and opportunities remain adequate.

The source provided does not include the CIO's specific prescriptions, asset class positioning, or quantitative evidence supporting the claim. Readers seeking the substance of the argument, including any proposed changes to asset allocation, risk frameworks, or governance, should consult the full Top1000funds.com article.
