Investing basics,
explained plainly.

A stock is a small ownership slice of a real company. When you buy one share of a company, you own a tiny fraction of its profits, assets, and future — that's why the price moves with how the business (and how investors feel about it) is actually doing, not just random noise. The price you see quoted is simply the most recent price someone agreed to pay for one share — it changes constantly as buyers and sellers meet in the middle.

Stock: a slice of ownership in one company. ETF (Exchange-Traded Fund): a single ticker that holds a whole basket of stocks (or bonds, or commodities) at once — buying one ETF share instantly spreads your money across everything inside it, which is why they're a common way to diversify without picking individual companies. Forex (FX): trading one currency against another (e.g. GBP/USD) — you're betting on how their exchange rate moves relative to each other, not on any company. Crypto: digital assets like Bitcoin or Ethereum that trade 24/7 on their own decentralized markets, not tied to any company's earnings. CFD (Contract for Difference): not an asset at all — a contract with a broker that pays out the price difference of something (often an index or commodity) without you ever owning the real thing, which is also why CFDs typically involve leverage and carry more risk than owning a stock or ETF outright.

Company executives and directors are legally required to publicly report ("Form 4" filings) when they buy or sell their own company's stock. An insider buying with their own money is a genuine vote of confidence — they know the business better than anyone outside it. A single small sale usually means nothing (it could just be paying a tax bill); a cluster of buys from multiple insiders at once is the signal actually worth paying attention to.

A price alert doesn't tell you what to do — it just tells you when to look. The most useful alerts aren't set on stocks you already own and check daily; they're set on stocks you're watching from a distance, so you get pulled in exactly when something changes, instead of either obsessively checking or missing the move entirely.

Putting all your money into one stock means one company's bad quarter can wipe out a big chunk of your savings. Spreading money across different companies, sectors, and asset types means no single piece of bad news can sink your whole portfolio — the tradeoff is that no single piece of great news can make it either. That tradeoff is the whole point.

A score like the one on AlfaFinances' stock pages combines several real, checkable inputs — recent price trend, analyst sentiment, insider activity, news tone — into one number, purely to save you from checking five different sources yourself. It's a starting point for your own research, not a prediction and not a recommendation to buy or sell — treat it the same way you'd treat one analyst's opinion, not a guarantee.

Never invest money you can't afford to lose or might need in the next few years. Markets go down as well as up, sometimes sharply and without warning — every guide on this page assumes you already understand that, and none of it is a substitute for your own research or a licensed financial adviser.
