Trend-Following Strategies in a Bull Market Regime

Identifying a Bull Market Regime

A bull market regime shows sustained upward price action. Define it using a 200-day simple moving average (SMA). Price must trade consistently above the 200-day SMA. The 50-day SMA must also trade above the 200-day SMA. Both moving averages must slope upwards. A common confirmation requires a 10% gain from a recent low. Volume typically expands on up days. Volatility, measured by the Average True Range (ATR), often decreases. The VIX index usually trades below 20. These metrics provide objective regime identification.

Strategy: Dual Moving Average Crossover

This trend-following strategy uses two exponential moving averages (EMAs). Use a 10-period EMA and a 30-period EMA. The strategy focuses on capturing medium-term trends. It avoids short-term noise. Apply this to liquid assets like S&P 500 ETFs (SPY) or large-cap stocks. Ensure the asset trades in a confirmed bull market regime.

Entry Rules

Execute a long entry when the 10-period EMA crosses above the 30-period EMA. This crossover must occur while both EMAs trade above the 200-day SMA. Price must close above the 30-period EMA on the entry day. Confirm the entry with above-average volume. Average volume is defined as the 50-day moving average of volume. A minimum volume increase of 20% above this average strengthens the signal. Place a limit order at the closing price of the signal candle. Execute at market open on the next trading day if price is favorable.

Exit Rules

Implement a trailing stop-loss. Place the initial stop-loss 1.5 times the current 14-period ATR below the entry price. Adjust the stop-loss daily. Move it to 1.5 times ATR below the previous day's low. This protects profits as the trend progresses. A primary exit signal occurs when the 10-period EMA crosses below the 30-period EMA. This indicates a potential trend reversal. Exit 100% of the position on this crossover. Another exit condition involves a hard stop-loss. If the asset declines 8% from its peak, exit the position immediately. This prevents large drawdowns. Consider a partial profit-take. Sell 50% of the position if the asset gains 15% from the entry price. This de-risks the trade. Adjust the remaining stop-loss to breakeven after the partial take.

Risk Parameters

Limit individual position size to 2% of total trading capital. Calculate this based on the initial stop-loss distance. For example, if a stock trades at $100 and the stop is at $95, the risk per share is $5. If total capital is $100,000, then 2% risk equals $2,000. This allows buying 400 shares ($2,000 / $5). Maintain a maximum portfolio exposure of 20% to any single sector. Overall portfolio risk should not exceed 10% of capital at any time. Use a 14-period ATR for volatility calculations. Re-evaluate regime status weekly. If the bull market regime conditions break, reduce position sizing by 50%. Cease new entries until the regime re-establishes itself.

Practical Application

Apply this strategy using a charting platform with EMA and SMA overlays. Backtest the parameters on historical bull market data. Focus on the 2010-2018 period for robust testing. Observe the drawdown characteristics. Aim for a maximum drawdown below 15%. Record all trades in a journal. Analyze win rates and average profit per trade. Adjust ATR multiplier for stop-loss based on asset volatility. A higher volatility asset might require a 2.0x ATR multiplier. A lower volatility asset might use 1.0x ATR. Execute trades during market hours. Avoid holding positions over major economic data releases if possible. This reduces event risk. Review portfolio performance monthly. Compare against a benchmark like SPY. Adjust strategy parameters based on performance review. This iterative process refines the approach.
