What are equities? When you buy a share you become a part-owner of that company. If the company grows and becomes more profitable, your share is worth more. You may also receive dividends — a share of profits paid out regularly.

Why hold them? Over any 15-year period, global equities have historically delivered 7-10% annual returns after inflation — far outpacing cash, bonds or property. The longer your time horizon, the more equities you should hold.

The risk: Markets can fall 30-50% in a bad year. The 2008 financial crisis saw global equities drop 50%. But they recovered within 5 years. Short-term volatility is the price you pay for long-term returns.

How to invest: Rather than picking individual stocks, use a global index fund like VWRP (Vanguard FTSE All-World). This gives you exposure to 3,700+ companies across 49 countries for an annual fee of just 0.22%. One fund, globally diversified, low cost.

Finn recommendation: Hold equities inside your ISA or pension to shelter gains from tax. For a balanced investor, 60% equities is a good starting point.

What are bonds? When you buy a bond you are lending money to a government (gilts) or company (corporate bonds). They promise to pay you interest (the coupon) and return your original money on a set date (maturity).

UK Gilts: Loans to the UK government — considered very low risk since the government can always print money to repay. Current yields around 4-5%. A good safe haven when equity markets fall.

Why hold bonds? Bonds typically move opposite to equities. When stock markets crash, investors flee to the safety of government bonds, pushing their price up. This cushions your overall portfolio.

The risk: Bond prices fall when interest rates rise (as happened dramatically in 2022). They also provide lower long-term returns than equities. Hold them for stability, not growth.

How to invest: Use IGLT (iShares UK Gilts ETF, OCF 0.07%) for low-cost UK government bond exposure. For a balanced portfolio, 20% in gilts is a reasonable allocation.

The risk-return relationship: There is no such thing as a high-return, low-risk investment. Anyone offering this is lying. Cash is low risk, low return. Equities are higher risk, higher return. Understanding this is the foundation of all investing.

Time reduces risk: In any single year, equities might return +30% or -30%. But over 20 years, the probability of a negative return approaches zero. Time smooths out volatility. The longer your horizon, the more risk you can afford.

Sequencing risk: If you are close to independence, a market crash just before you stop working is devastating — you are forced to sell at low prices. This is why you reduce equity exposure as you approach your independence age.

Volatility vs permanent loss: Most investors confuse the two. A 30% market crash is volatility — it recovers. A company going bankrupt is permanent loss. Diversification protects against permanent loss. Time protects against volatility.

Finn rule of thumb: Subtract your age from 110 to get your rough equity percentage. Age 40 = 70% equities. Age 60 = 50% equities. Adjust based on your risk appetite and time to independence.

How it works: If you invest £10,000 at 7% per year, after year 1 you have £10,700. In year 2 you earn 7% on £10,700 — not just the original £10,000. Your returns earn returns. This compounds exponentially over time.

The numbers: £10,000 invested at 7% for 10 years = £19,672. For 20 years = £38,697. For 30 years = £76,123. The same money, just more time. The last 10 years generated more than the first 20 combined.

Why starting early matters so much: £5,000 invested at age 25 is worth more at 65 than £20,000 invested at age 45. The 20 extra years of compounding more than compensates for the smaller amount.

The enemy of compounding: Fees, taxes, and stopping. A 1% annual fee sounds small but destroys 25% of your wealth over 30 years. This is why low-cost index funds (VWRP at 0.22%) beat actively managed funds (typically 1-2% fees) over long periods.

Finn tip: Reinvest every dividend. Never withdraw from your portfolio before your independence date. Let compounding work uninterrupted — every year you leave it alone it gets more powerful.

Why diversify? If you own one company and it goes bankrupt, you lose everything. If you own 3,700 companies (like VWRP), one bankruptcy barely registers. Diversification eliminates company-specific risk without reducing your overall expected return.

Across asset classes: Equities, bonds, property and cash behave differently in different economic conditions. When equities crash, bonds often rise. When inflation is high, property tends to hold value. Holding all four smooths your overall journey.

Geographic diversification: The UK is just 4% of global market capitalisation. Owning only UK stocks concentrates your risk in one economy. A global fund like VWRP gives you the US (65%), Europe, Asia and emerging markets.

The limit of diversification: Diversification eliminates company-specific risk but cannot eliminate market risk — when the whole world economy crashes, everything falls together. This is why time horizon matters.

Over-diversification: Owning 20 different funds that all hold the same underlying stocks is not diversification — it is complexity. One good global fund is more diversified than 10 overlapping ones.

What is inflation? The general rise in prices over time. UK inflation has averaged around 2-3% per year historically, though it spiked above 10% in 2022-23. At 3% inflation, something that costs £100 today will cost £180 in 20 years.

Real vs nominal returns: If your savings account pays 4% interest and inflation is 3%, your real return is just 1%. If inflation is 4%, your real return is zero — you are standing still. Always think in real terms.

Cash is guaranteed to lose value: Over long periods, cash savings accounts rarely beat inflation after tax. Holding too much cash is not playing it safe — it is guaranteeing a slow loss of purchasing power.

What beats inflation: Equities (7% real return historically), property (3-4% real), and index-linked gilts (designed to track inflation). Bonds and cash typically lag inflation over the long run.

Finn uses real returns: All projections in Finn use real (inflation-adjusted) return assumptions. The 7% used for equities is after inflation. This means the pound amounts shown are in today's money — what they would actually buy.
