If you’re a University employee, you likely have access to retirement plans like the 403(b), 401(a), and 457(b). But once you’re enrolled, how do you actually invest the money in these accounts? Understanding the basic investment options available—Mutual Funds, ETFs, and Annuities—can make a significant difference in your retirement outcomes. At Provizr, our goal is to simplify investing so you can confidently take control of your financial future.
Mutual Funds: The Retirement Investing Staple
Mutual funds are a cornerstone of most University retirement plans. Think of a mutual fund as pooling your money with many other investors to buy a wide variety of assets, managed professionally for you.
Highlights for University Employees:
Easy diversification: Your investment is automatically spread across many assets.
Professional management: Fund managers make decisions on buying and selling assets, aiming for growth or income.
Widely available: Offered in most Fidelity and TIAA University plans.
Pros:
Simplicity and convenience
Professional management
Automatic diversification
Cons:
Fees vary (some higher than others)
Limited direct control over specific investments
Exchange-Traded Funds (ETFs): Flexible & Cost-Effective
ETFs, or Exchange-Traded Funds, are similar to mutual funds but are traded like individual stocks on the market. They offer diversification but often at a lower cost.
Highlights for University Employees:
Lower fees: ETFs typically have lower expense ratios, which can enhance your long-term returns.
Transparency: You know exactly what you’re investing in since ETFs track specific market indices.
Increasing availability: Now common in Fidelity-managed University retirement plans, especially in supplemental plans like the 457(b).
Pros:
Lower investment costs
Clear investment transparency
Flexible trading (though typically less relevant for long-term investing)
Cons:
Potential temptation to trade frequently, which can hurt long-term growth
Not universally available in every retirement account
Annuities: Guaranteed Income With TIAA
An annuity provides guaranteed, predictable income in retirement. TIAA, commonly available to University employees, is well-known for its annuity offerings.
Two main annuity types within University plans:
Fixed Annuities (TIAA Traditional): Guarantees a set income, providing stability and predictability.
Variable Annuities: Your returns fluctuate based on underlying investment options, offering potential growth but with market risk.
Highlights for University Employees:
Lifetime income guarantees—ideal if you value stability and certainty.
Reduced financial stress, particularly for core expenses during retirement.
Pros:
Lifetime guaranteed income
Predictability and security
Reduces uncertainty in retirement planning
Cons:
Less flexible; typically irreversible decisions
Potentially limited protection against inflation (particularly with fixed annuities)
How to Choose the Right Investment for You
When deciding among Mutual Funds, ETFs, and Annuities, consider these factors:
Risk tolerance: How comfortable are you with market ups and downs?
Time horizon: How long until you plan to retire?
Financial goals: Do you prefer growth, stability, or a balanced combination?
Most importantly, combining several investment types can offer the best of all worlds—growth potential, flexibility, and income stability.
