CREF Stock Account Review: Is It Time to Diversify?

If you have a TIAA account, chances are a significant portion of your money is in the CREF Stock Account. It is one of the largest variable annuities in the world, serving as the default growth engine for hundreds of thousands of university employees. But as we enter 2026, the question must be asked: is this broad-market dinosaur still the best way to capture equity growth?

The "Wrapper" Problem

The CREF Stock account isn't just a mutual fund; it's a variable annuity. This distinction is critical. Because it's an annuity, it comes with a "wrapper" that includes mortality and expense (M&E) charges. These charges are ostensibly there to pay for the "guarantee" that you can turn your balance into a lifetime income stream later. But if you don't plan on annuitizing your entire balance, you are paying for an insurance feature you will never use.

Our audit of the 2026 expense ratios shows that the CREF Stock account costs roughly 0.35% to 0.45% depending on your specific plan. While that sounds low compared to high-commission retail products, it is vastly more expensive than a standard Total Stock Market Index fund, which might cost 0.03%.

Performance vs. Benchmark

CREF Stock attempts to track a composite benchmark (roughly 70% US stocks, 30% international). In our analysis, it does a "fine" job—but rarely an exceptional one. Because it is so large, it essentially acts as an index fund but with an active management fee. Over the last ten years, it has trailed a simple two-fund index portfolio (VTSAX + VTIAX) by a margin that almost exactly matches its higher expense ratio.

Strategic Alternatives

If your plan allows it, we suggest looking for the "TIAA-CREF Institutional" mutual funds instead of the CREF variable annuity accounts. Often, the exact same underlying assets are available in a mutual fund format for 0.10% to 0.20% less. By switching from the annuity to the mutual fund, you keep more of your returns without changing your market exposure.

Conclusion

CREF Stock is a safe, middle-of-the-road choice, but it is rarely the optimal one. For educators with 10+ years to retirement, the friction of annuity fees is an unnecessary drag on performance. We recommend auditing your plan for lower-cost "mutual fund" equivalents or low-fee index funds at competing providers like Vanguard.
