株式とは
株式は企業の一部を持つことです。可能性はありますが、責任と変動も大きくなります。
重要ポイント
- 企業の持ち分を買う
- 価格は期待で動く
- 配当は保証されない
- 集中はリスクを高める
How it really works
If you buy a stock, your outcome comes from price movement and, when present, dividends.
The price moves on future expectations, not only on past results.
When single stocks make sense
They make sense if you accept high volatility and can be wrong without damaging the whole portfolio.
For beginners, keeping single stocks as a small satellite allocation is usually healthier than building everything around stock picking.
Common mistake
A great product is not automatically a great investment: a company can be excellent while its price is already too expensive.
Position sizing matters more than personal conviction.
次にすること
If you want to start with single stocks, set a clear limit and respect it: a small portfolio slice chosen calmly, not through FOMO.
