What $100 Invested in 1928 Would Be Worth Today

Many people think the biggest risk with money is losing it — a bad investment, a market downturn, or a decision that doesn’t work out as planned.

But another risk that is often overlooked is the impact of not investing at all over long periods of time.

Historical data offers perspective, but it’s important to remember that past performance does not guarantee future results.

What $100 Looked Like in 1928

In the late 1920s, $100 had significantly more purchasing power than it does today. Over time, inflation has reduced what a dollar can buy.

That’s the nature of inflation. It tends to work gradually, often without drawing attention, while reducing purchasing power over time.

Three Paths, Three Different Outcomes

If $100 had been allocated in different ways starting in 1928, the long-term results would have varied significantly based on historical averages:

• Cash (not invested): The value remains $100, but purchasing power declines over time due to inflation.
• U.S. government bonds: Historically, bonds have provided income and growth potential, with lower volatility than stocks. Returns have varied over time.
• A broad stock market index: Historically, equities have provided higher long-term growth potential, but with greater short-term volatility and periods of loss.

Over long periods, these differences have led to a wide range of outcomes. However, these examples are hypothetical, based on historical data, and do not reflect actual investor experience, which would include fees, taxes, and changing market conditions.

Why “Safe” Can Mean Different Things

Cash can feel stable because its value doesn’t fluctuate. However, it may not keep pace with inflation over time.

Bonds have historically offered a balance between stability and growth, though they are also subject to interest rate and market risks.

Stocks have historically provided growth potential, but they can fluctuate significantly and are not appropriate for every investor or every timeframe.

The Role of Time and Staying Invested

One consistent theme in long-term market data is the impact of time in the market.

Market returns have varied year to year, sometimes significantly. Investors who remained invested through different market cycles have historically experienced different outcomes than those who moved in and out of the market, though there are no guarantees.

Research often shows that missing periods of strong market performance can affect overall returns, but market timing is difficult and involves risk.

What This Means for Today

This is not a recommendation for any specific investment strategy.

Every financial decision should take into account your individual goals, risk tolerance, time horizon, and overall financial situation.

However, history suggests that factors like diversification, time horizon, and consistency can play important roles in long-term investing outcomes.

There’s no way to predict future market performance. But reviewing your current strategy and how it aligns with your goals is a practical step you can take.

If it’s been a while since you’ve revisited your investment approach, a conversation may help bring clarity.
