📈 Why Stocks?

Over the long term, stocks have outperformed every other major asset class – including bonds, real estate, and gold. The reason is simple: stocks represent ownership in productive businesses that grow their earnings and dividends over time.

Since 1926, the U.S. stock market (S&P 500) has delivered an average annual return of about 10% before inflation. While returns are never guaranteed, history shows that patient investors are rewarded.

⚡ The Engines of Growth

Compounding

When your returns generate their own returns, wealth grows exponentially. A $10,000 investment earning 8% annually becomes $46,610 in 20 years – without adding a single dollar.

Beating Inflation

Inflation erodes purchasing power. Stocks have historically returned 6‑7% above inflation, preserving and increasing your real wealth.

Risk Premium

Stocks are riskier than bonds or cash, so investors demand a higher return – the "equity risk premium". Over decades, that premium adds up.
