Stock
What a stock is and why it matters in investing.
Plain-English definition
A stock is an ownership claim on a company. When you buy a stock, you participate in the value created or destroyed by that business over time.
Why it matters
Most investment research starts by deciding whether a stock deserves closer analysis, comparison, or monitoring.
Beginner example
A beginner might ask whether NVDA is a strong stock because of earnings growth, valuation, or market leadership.
Common misunderstanding
A stock is not just a chart or a ticker symbol. It is a business, a valuation, and a market narrative at the same time.
