【UNFX课堂】为什么巴菲特反对它，而西蒙斯依赖它趋势跟踪的哲学分裂

Core Concepts - Trend following is not blind speculation; it emphasizes acting in accordance with market trends and avoiding counter-trend operations [1] - Price reflects all fundamentals, sentiment, and policies, ultimately manifesting in price trends [2] - Cut losses quickly and let profits run; quickly stop losses on losing trades while holding profitable trades until the trend ends [3] - Trends have inertia; once established, they are more likely to continue than to reverse [4] - Do not predict; instead, react to market signals and follow trends [5] Trend Identification - Moving Average System: A bullish signal occurs when a short-term moving average crosses above a long-term moving average (e.g., 5-day > 20-day) [6] - Channel Breakout: Enter long when price breaks above the N-day high and short when it breaks below the N-day low [6] - Momentum Indicators: An expanding MACD histogram indicates trend acceleration [6] - Trend Structure: Higher highs and higher lows indicate an uptrend, while lower highs and lower lows indicate a downtrend [6] - Volatility Confirmation: A breakout of the Average True Range (ATR) from recent averages signals trend initiation [6] Strategy Execution - Entry Rules: Enter trades on price breakouts with increased volume or on pullbacks to moving averages [7] - Position Sizing: Limit single trade risk to 1% of total capital [7] - Stop Loss Settings: Use volatility-based stops (±2 times ATR) or structural stops based on previous highs/lows [7] - Profit Taking Logic: Implement trailing stops based on a percentage retracement from the highest price [7] - Multi-Market Adaptation: Different strategies for various asset classes, such as focusing on moving averages for stock index futures and momentum indicators for cryptocurrencies [7] Risk Management - Diversification: Hold 5-10 non-correlated trend positions simultaneously [8] - Leverage Control: Limit futures leverage to 5 times and cryptocurrency leverage to 3 times [8] - Drawdown Triggers: Enforce a 50% reduction in positions if account drawdown reaches 15% [8] - Correlation Monitoring: Reduce positions if the correlation coefficient among holdings exceeds 0.7 [8] Cognitive Misconceptions - Trend following is not equivalent to long-term holding; exit immediately when a trend ends [9] - Holding periods typically range from days to months, not high-frequency trading [9] - Avoid over-optimization, which can lead to failure in real trading [9] - Emotional interference can lead to premature exits; adhere to trailing stops [9] Practical Cases - Oil Price Crash 2020: Trend signals indicated a short position after breaking the 200-day moving average [10] - Nvidia AI Surge 2024: Trend initiation was confirmed by a weekly MACD crossover [10] - Federal Reserve Rate Hikes: The dollar index rose 15% during the 2022 rate hike cycle, validating breakout strategies [10] - Bitcoin Halving Trends: Historical data shows significant price increases following halving events [10]
