In view of market fluctuations, high-risk and high-return trading methods do exist, but it should be noted that these strategies require extremely high trader experience, risk tolerance and discipline. Here are some common strategies and their key points： ### 1. Leveraged trading 1. **Leveraged ETFS/ETN**(3 times leveraged products) -Case study: When the S&P 500 fluctuates by 3% in a single day, the 3 times leveraged ETFs may amplify to 9% of the gains (or losses) -Risk: The effect of leverage loss is obvious. In the Crude oil treasure incident in 2020, some leveraged products lost more than 60% in a single week.% 2. **Foreign exchange margin trading** -Leverage ratio of up to 500:1 (as permitted by Japanese regulation) -Potential risks: The Swiss franc Black Swan incident in 2015, the bankruptcy of a number of foreign exchange brokers, and the liquidation of customer accounts ###2. Derivatives strategy 3. **Naked short selling options** -Sell virtual call options (such as selling a看涨300 call option when Tesla's stock price is$250) -The maximum return is limited (premium), but the risk is unlimited (100% margin is required) 4. **Straddle option combination** -Buy call and put options with the same exercise price at the same time (such as the layout of Apple options before the release of the earnings report) -The cost is high, and the decline in implied volatility may lead to a double kill (such as a 40% plunge in IV after the Meta earnings report in 2022) ###3. Special scenario transactions 5. **Stock speculation in bankrupt companies** -Case study: Revlon's stock price plunged from$9 to$0.2 before its bankruptcy in 2022, but retail speculation caused a single-day surge of 300% -Risk: 99% probability returns to zero, but there is a possibility of bankruptcy reorganization (such as the rebound in the stock price of Hertz Car Rental after bankruptcy in 2020) 6. **Cryptocurrency futures** - 100 times leverage is common on exchanges such as Binance - Extreme case: Bitcoin fell from$60,000 to$30,000 in 2021, resulting in a burst of positions at the level of$1 billion ###4. Event-driven strategy 7. **FDA new drug approval process** -Focus on biomedical stocks (such as the share price of Moderna's New Crown vaccine soared from$20 to$500 during the approval period) -Risk: Sarepta Therapies' new drug was rejected in 2018, and its stock price plunged 60% in a single day.% ###5. Special market opportunities 8. **Hong Kong Stock Certificate (Warrant)** -Varieties with an average daily turnover rate of more than 100% are common -Significant time loss: Out-of-price warrants usually lose more than 50% of their value in the last 10 days 9. **A-share convertible bond speculation** -T+0 transaction + no limit on rise or fall (for example, Blue Shield bond-to-bond orders skyrocketed by 70% on a daily basis) -Strong redemption risk: In 2023, Yokogawa's debt-to-debt redemption will cause investors to lose 80% of their income.% ### Key risk control recommendations： 1. **Position size control**: A single transaction does not exceed the principal amount 2% 2. **Fuse mechanism**: Set 10% hard stop loss +5% warning line 3. **Volatility monitoring**: Reduce leverage when the VIX index is >40 4. **Black Swan hedging**: Allocate 5% of funds to buy virtual put options 5. **Liquidity management**: Ensure that more than 50% of funds remain in cash condition ### Real risk case： -The Lun Nickel incident in 2022: Qingshan Holdings suffered a short-selling loss of US88 billion in a single day due to short-selling. - Negative oil price event in 2020: WTI crude oil futures fell to -37 US dollars, and long positions fell into arrears to brokers High-risk trading is essentially a game of probability. It is recommended to use a demo account to test for more than 6 months. For real trading, it is recommended to start with the smallest trading unit (such as 1 lot). Remember: Under 100 times leverage, a reverse fluctuation of 1% can lead to a total loss of principal. Be sure to assess your own risk tolerance before making a decision.
