Risk Disclosure

Share prices go down as well as up. You may get back less than you put in, and a company can fail, making its shares worthless. Only invest money you can afford to lose, and spread your risk.

• Daily price limits: most Korean stocks can rise or fall at most 30% from the previous close in one day. A stock can hit its limit and stay there, so you may not be able to sell when you want to, and a big move can carry on over several days.
• Trading halts: the exchange can pause trading in a stock, or the whole market, after big moves (circuit breakers and volatility interruptions), or when a company has problems. Shares can be suspended for a long time or delisted.
• Currency risk: Korean shares are priced in Korean won. If the won falls against your home currency, your investment can lose value even if the share price doesn't change. Prices we show in other currencies are converted for convenience only.
• Small companies: many KOSDAQ and small KOSPI companies are thinly traded. Prices can swing sharply, it can be hard to buy or sell without moving the price, and they're more often targets for hype and manipulation.
• Short selling: Korea's short-selling rules are strict and have changed several times, including market-wide bans. Rule changes can move prices quickly.
• Trading hours: the regular session runs 9:00 to 15:30 Korea time (KST), which may be the middle of the night where you live. News can come out while the market is closed, and prices can open far from the last close.
• Foreign investors: there can be extra rules, taxes, account requirements and limits on how much of some companies foreigners may own.

How a stock, theme, strategy or person did in the past doesn't tell you how they'll do in future.

Strategy results and backtests show what would have happened if a set of rules had been followed in the past. They're built with hindsight, can't fully include real costs, taxes, price limits, liquidity or the difficulty of borrowing shares, and may be based on limited history. Real results are usually worse.
