Don't put it all in one stock
If it falls, you fall with it. Here's how to split.
When someone says "this stock can only go up," you sometimes feel like throwing in everything you have. But the first thing to learn in investing isn't 'how much can I make' — it's 'how do I not lose.' Today, that first step: diversification.
Why is putting it all in one stock risky?
Put your whole savings in one stock, and when that company wobbles, all your money wobbles with it. Even the best-looking company can hit an unexpected accident, weak earnings, or bad news. Bet it all on one place and you have no room to survive that one hit.
So how do you split it up?
Think of splitting in three directions. First, across multiple companies. Second, across multiple sectors like semiconductors, bio, and finance. Third, across multiple countries like Korea and the U.S.
Split this way, when one side does badly another side props you up. The odds of everything collapsing at once are far lower.
Can you split too finely?
On the flip side, spreading tiny amounts across too many stocks makes them hard to manage and fills your list with companies you barely know. For beginners, 5 to 10 companies you can actually understand is about right. 'Do I know it?' matters more than the count.
Today's recap
Diversification is the most basic seatbelt for 'losing less.' Split across companies, sectors, and countries, and start only with as much as you understand. Surviving long comes before winning big.
