Size Your First Position

How much to put into your first stock: start small, choose the stop from the chart, and let a small risk budget decide the number of shares.

The question most beginners skip

New investors spend hours choosing a stock and seconds deciding how much to buy. Yet position size often matters more than the pick. A good stock bought far too large can still hurt you if it drops at the wrong time, and a mediocre pick bought at a sensible size is a cheap lesson.

Your first position has one main job: to teach you how it feels to own a stock through its ups and downs, without putting your financial future on the line. That calls for a small, deliberate size.
