Investing for the Medium Term

When you invest in a company's shares, you own a small piece of it. If the company grows and becomes more valuable, your share grows in value. If it pays dividends (a portion of profits to shareholders), you receive income. Over long periods, equity markets have historically returned 6–10% annually after inflation — far higher than cash savings.

Why markets go up long-term

Economies tend to grow. Companies tend to adapt and innovate. The value of productive assets tends to increase over time. This is not guaranteed — individual companies fail, markets crash, decades can underperform — but over 20+ year periods, globally diversified equity investment has consistently beaten inflation and cash savings.

Volatility is normal

Markets fall. 20% drops are normal. 40% crashes happen. The 2008 financial crisis wiped 50% off equity values. Every single one of those crashes was followed by a recovery that exceeded the previous peak — if you stayed invested. The investors who lost permanently were those who sold at the bottom.

Why not pick stocks?

Most professional fund managers underperform a simple index tracker over 10+ years, after fees. Individual stock picking requires substantial research, diversification across many holdings, and emotional discipline most people don't have when their own money is involved. The evidence strongly favours low-cost passive investing for most people.

Index funds and ETFs

An index fund tracks a market index — the FTSE 100, the S&P 500, or a global index like the MSCI World or FTSE Global All Cap. When you buy a global index fund, you're buying tiny slices of thousands of companies across dozens of countries. One fund, instant diversification.

The Vanguard FTSE Global All Cap Index Fund

One fund. 7,000+ companies. 50+ countries. Covers large, medium, and small companies worldwide, weighted by market cap. Annual charge: approximately 0.23%. This is the "one fund" solution for most people who don't want to think about allocation.

If you want to be slightly more hands-on

A simple two-fund portfolio: 80% global index fund (e.g. Vanguard FTSE All World), 20% bonds (e.g. Vanguard Global Bond Index). The bonds reduce volatility slightly. As you approach retirement, shift toward a higher bond allocation. This is the Bogle-style approach followed by millions of passive investors.
