Fidelity sends critical message to cash-heavy investors

If you have been holding cash while the stock market posted three straight years of gains above 15%, Fidelity Investments has a message for you.

The firm published a seven-step guide to help cash-heavy investors overcome hesitation and build a diversified portfolio, arguing that excess cash carries a compounding cost that grows every quarter.

Money market yields have dropped from above 5% in mid-2024 to roughly 3.6% to 4% as of early 2026, tracking the Federal Reserve’s 175 basis points of rate cuts since September 2024.

The S&P 500 delivered total returns of approximately 26.3% in 2023, 25% in 2024, and 17.9% in 2025.

Fidelity’s 7 steps for deploying excess cash

Fidelity’s framework addresses the psychological weight keeping people from deploying their money.

1. Let go of missed investments

Fidelity’s first step urges cash-heavy investors not to dwell on missed gains from staying on the sidelines.

Not investing aggressively enough is one of Americans’ most common financial regrets, cited by 25% of respondents in a Quicken survey of roughly 1,000 people conducted in November 2023.

Financial decisions are inherently personal; it’s important to balance best practices with each life stage, current state of the economy, and your financial standing.

Rather than fixating on lost opportunities, the firm advises making a plan to move forward and look for openings in the market.

2. Focus on future opportunities

The stock market offers no guarantees in any given year, Fidelity notes, but it points out that stocks and bonds have historically delivered stronger growth than cash over long periods.

A diversified portfolio suited to an investor’s comfort level, goals, and broader financial plan, the firm argues, offers a realistic chance to participate in the market’s next move higher.

3. Figure out the big picture

Building a portfolio from scratch can feel overwhelming, but Fidelity recommends breaking the process into two foundational decisions. 

First, determine how much risk you can actually handle, not just financially, but emotionally.

Then set your asset allocation. A higher risk tolerance generally means a heavier weighting toward stocks. A lower one tilts the mix toward bonds and cash.

4. Consider which investments could work for you

This is where many investors stall out. The sheer number of options, individual stocks, bonds, mutual funds, and ETFs creates “analysis paralysis” that keeps cash parked on the sidelines indefinitely.

Fidelity’s advice is refreshingly direct: You do not need to research every ticker on the market. 

You need a diversified mix that matches the risk profile you just built. A single target-date fund or a professionally managed account can get you there without requiring hours of individual stock analysis.

5. Pick an investing pace

Once an investor knows how the portfolio should look, Fidelity lays out two ways to buy in: all at once, or gradually over time.

The firm says investing a lump sum gives money more time in the market, which can offer the potential to beat a slower approach. On the other hand, dollar-cost averaging spreads purchases across regular intervals, regardless of price.

Fidelity does not declare a winner between the two. The right choice depends on your cash position and your emotional bandwidth for watching your balance swing in the early days.

6. Hold onto your investments

Fidelity warns that obsessing over perfect trade timing is a losing strategy for most retail investors. Missing even a handful of the market’s best-performing days can put a serious dent in your long-term returns. 

Those best days tend to cluster right alongside the worst ones, which means investors who panic-sell during downturns often miss the sharp rebounds that follow.

7. Get help if you need it

Trusting money to the markets can be nerve-wracking, Fidelity acknowledges.

If following through on an investing plan proves difficult, the firm suggests checking in with a financial professional rather than defaulting back to cash, adding that there is nothing wrong with asking for help.

Why Fidelity is advising cash deployment now

The timing of Fidelity’s seven-step guide is not accidental. Money market yields have been sliding steadily since the Federal Reserve began cutting rates in September 2024, shrinking the returns that made cash feel like a safe and productive place to park money. 

What once looked like a reasonable 5% yield has dropped closer to 3.8%, and further cuts could push that number lower still.

Meanwhile, the S&P 500 has posted three consecutive years of double-digit gains, widening the gap between what cash holders earned and what invested capital returned.

Fidelity’s framework appears designed to reach the segment of its client base that watched those gains from the sidelines and still has not made a move. The firm is essentially arguing that the window where cash feels competitive is closing.

Both T. Rowe Price and U.S. Bank have published research that reached a similar conclusion about the long-term drag excess cash creates on portfolio performance.

The consensus among major financial institutions is pointing in the same direction, which makes Fidelity’s step-by-step approach notable.

The compounding cost of excess cash grows larger the longer investors delay

T. Rowe Price found that compared to an investor who funneled $12,000 a year into cash, an investor who steadily contributed the same amount to a diversified 60/40 stock-and-bond portfolio would have built a substantially larger balance over both five- and 30-year periods ending Dec. 31, 2025.

The firm’s analysis, which used the S&P 500, the Bloomberg U.S. Aggregate Bond Index, and short-term Treasury bills as proxies, illustrates a cost that rarely registers in the moment. Cash left on the sidelines forgoes the compounding that drives long-term growth, and the gap widens the longer the money sits.

U.S. Bank reached the same conclusion from a different angle, noting that with investors holding more than $7 trillion in cash-equivalent securities, falling yields are steadily raising the opportunity cost of staying put.

As the Federal Reserve lowers rates, the firm cautioned, the returns on cash-equivalent instruments fall with them.

Fidelity’s seven-step framework breaks the transition from cash to a diversified portfolio into incremental decisions rather than a single high-stakes move.

Each step builds on the one before it, shifting from mindset adjustments in the early stages to concrete portfolio mechanics in the later ones, according to the firm.
