Start with three practical lessons.
Read every lesson on this page, without creating an account or providing contact details. Each lesson includes an explanation, a fictional worked example and a self-check with an answer.
Lesson 01 · Market foundations
Share price, company value and order execution
Price per share is only one part of the picture
A share represents an ownership interest in a company. Market capitalization is the current share price multiplied by the number of outstanding shares. Comparing share prices alone can therefore be misleading: a lower-priced share does not automatically represent a smaller company or a cheaper valuation.
Worked example — fictional companies
Company A has 1 million shares priced at $20 each. Its market capitalization is $20 million. Company B has 10 million shares priced at $5 each. Its market capitalization is $50 million.
B has the lower price per share but the higher market capitalization. Neither number tells us whether either business is a suitable investment.
A displayed quote is not an execution promise
Prices can change between viewing a quote and an order reaching the market. A market order seeks execution at available prices; it does not guarantee a specific price. A limit order sets the maximum purchase price or minimum sale price, but may remain unfilled. Liquidity describes how readily a security can be traded; limited trading interest can make execution more difficult.
Self-check: What does a $10 buy limit mean?
It limits the purchase price to $10 per share or less, excluding fees. It does not guarantee that any shares will be purchased. The order's duration and other conditions also matter.

Lesson 02 · Financial statements
How a business can report profit without receiving cash
Financial statements describe different aspects of a business. A balance sheet captures assets, liabilities and shareholders' equity on a particular date. An income statement describes revenue and expenses over a period. A cash-flow statement records cash movements, commonly grouped into operating, investing and financing activities.
Understand the basic relationship
The balance-sheet equation is assets = liabilities + shareholders' equity. Revenue is different from profit: expenses reduce revenue to determine earnings. Profit is also different from cash generation, because accounting can recognize a sale before payment is received.
Worked example — fictional business, simplified figures
A company has assets of $150,000 and liabilities of $90,000. Its equity is $60,000: $150,000 − $90,000.
It then records a $10,000 sale on credit and an associated expense of $6,000. In this simplified transaction, profit is $4,000 before other expenses and taxes, while no cash has yet been collected from the customer. The unpaid amount is a receivable.
Read the statements together
Reviewing all three statements and their notes helps explain the business beyond any single headline number. Accounting estimates, one-off events and the reporting period can affect comparisons.
Self-check: Are $60,000 of equity and $60,000 of cash the same thing?
No. Equity is the accounting residual after liabilities are subtracted from assets. Assets may include inventory, buildings or receivables as well as cash. Equity is not a statement of how much cash the business holds.

Lesson 03 · Risk awareness
Loss, recovery and the limits of diversification
Losses and gains use different starting values
A percentage change is calculated from the value at the start of that change. After a loss, the starting value is smaller. An equal percentage gain therefore does not restore the original amount.
Worked example — arithmetic, not a forecast
An illustrative $1,000 holding falls by 20% to $800. A subsequent 20% rise adds $160, leaving $960.
Returning from $800 to $1,000 requires a 25% gain: ($1,000 − $800) ÷ $800 = 25%. Fees, taxes and inflation are excluded.
Diversification reduces some risks, not all risks
Diversification means spreading exposure across different investments. It can reduce the effect of a problem affecting one company or sector, but cannot guarantee that a portfolio avoids losses. Several holdings may still be concentrated if they depend on the same industry, region or economic conditions. Broad market declines can affect many investments together.
Time horizon and risk tolerance are different ideas
Time horizon describes how long it may be before money is needed. Risk tolerance concerns the ability and willingness to accept losses. A longer horizon does not make an investment risk-free, and short-term price volatility is not the only risk: permanent loss, liquidity and purchasing power also matter.
Self-check: Does owning ten companies guarantee diversification?
No. Ten companies in the same sector can share many of the same risks. The number of holdings alone does not describe how their exposures overlap, and even a broadly diversified portfolio can lose value.

Our approach
Learn the framework—and its limits.
Define the concept
Begin with plain-language definitions and the context in which a term is commonly used.
See how it connects
Understand relationships between business performance, market data and investor expectations.
Identify limitations
Learn why no single metric, chart or framework can determine a future outcome.
Important risk notice
