The most mathematically tested path, with the lowest effort relative to the return obtained. A single ETF on the S&P 500 index gives you, in one move, exposure to 500 American companies at the same time — Apple, Microsoft, Nvidia, JPMorgan, Coca-Cola, all in one instrument. A global ETF such as MSCI World gives you more than 1.500 companies from 23 developed countries.
Over the last 10 years (2016–2025), the S&P 500 generated an average return of approximately 13,9% per year, with dividends reinvested. 8 years out of 10 were positive, 2 years negative (2018: -6,2% and 2022: -19,4%).
The difference between a term deposit in lei (4,3%) and an ETF on the S&P 500 (~10% historical average over 30 years, ~14% over the last 10 years) is easy to see with a simple example. You put 100.000 lei today, one time, and forget about it for 25 years:
- Lei deposit at 4,3%: 100.000 → ~285.000 lei (growth of 2,85×)
- S&P 500 at 10% historical average: 100.000 → ~1.080.000 lei (growth of 10,8×)
The difference is almost 800.000 lei — with no additional effort, only the difference between where the money sits. At larger sums and longer horizons, the difference grows exponentially.
Bear markets and recoveries. Capital markets do not grow linearly. Every 2–3 years, on average, a decline of 20–30% appears (bear market). Recent example: in April 2025, the S&P 500 reached -21% below its February peak. For the investor who understands the statistics and does not sell in panic, such moments are opportunities. From the low on 7 April 2025 to 22 May 2026, the S&P 500 rose by +53,9%. Whoever bought more in April 2025 effectively doubled the return of the path that followed.
