A stock (or share) is a small piece of ownership in a company. When you buy a share of Apple, you literally own a tiny slice of Apple Inc.

Companies sell shares to raise money. As the company grows, those shares become more valuable — and that's how investors make money. The price goes up and down based on how investors feel about the company's future.

Dollar-Cost Averaging (DCA) means investing a fixed amount at regular intervals — say £100 every month — instead of putting it all in at once.

When prices are high, your £100 buys fewer shares. When prices are low, it buys more. Over time, this smooths out your average buy price and removes the stress of trying to "time the market."

Most long-term investors use DCA. It's the strategy behind pension contributions and index fund investing.

An ETF (Exchange-Traded Fund) is a basket of stocks you can buy as a single investment. The S&P 500 ETF (like VOO or SPY), for example, holds the 500 largest US companies — so one purchase gives you exposure to all of them.

ETFs are cheap, diversified, and don't require you to pick individual stocks. Warren Buffett famously said most people would be better off just buying an S&P 500 index fund and doing nothing.

A return is how much your investment grew (or shrank) as a percentage. If you invested £1,000 and it's now worth £1,500, your return is +50%.

Annualised return is the average return per year over a period. A 100% return over 10 years is roughly a 7.2% annualised return — much less dramatic than it sounds.

Compounding is when your returns generate their own returns. If your £1,000 grows 10% to £1,100, then next year that 10% applies to £1,100 — not the original £1,000.

Over 30 years at 10% annually, £1,000 becomes over £17,000. That's the power of doing nothing and letting time work. Einstein allegedly called it the "eighth wonder of the world."

The single most important thing you can do is start early. Even small amounts compound into significant sums given enough time.

Higher potential returns almost always come with higher risk. Bitcoin might 10x — but it might also fall 80%. The S&P 500 has never had a 20-year losing period in history, but in any single year it can drop 30%+.

Diversification is the main tool to manage risk — spreading investments across different stocks, sectors and asset classes so one bad bet doesn't sink everything.

Your risk tolerance depends on your time horizon. If you won't need the money for 20 years, short-term volatility matters less than if you need it in 2.

Stocks represent ownership in real businesses with revenue, employees and assets. Their value is tied to company performance.

Crypto is more speculative — its value is driven largely by supply, demand and sentiment rather than business fundamentals. That's why it's more volatile in both directions.

Many investors hold both: stocks as their core long-term wealth builder, and a small crypto allocation as a higher-risk, higher-reward side bet. Never invest in crypto more than you can afford to lose entirely.

In the UK, a Stocks & Shares ISA lets you invest up to £20,000 per year completely tax-free. Any gains, dividends or returns inside the ISA are yours to keep — HMRC can't touch them.

Most beginner-friendly brokers (Trading 212, Freetrade) offer ISAs. It's almost always worth maxing out your ISA allowance before investing outside it.

If you have a pension or SIPP, contributions are also tax-deductible — meaning the government effectively tops up your investment.
