Virexan Capital’s Approach to Trend Following in Nifty/BankNifty
"The trend is your friend until the bend at the end." This cliché holds truth. Trend following is one of the oldest and most robust alpha sources. Here is how we approach it for the Indian Index workflows.
The Core Philosophy
We do not try to buy the bottom or sell the top. We aim to capture the "meat" of the move. If a trend moves from 100 to 200, we are happy entering at 120 and exiting at 180.
The Engine: Volatility Breakout
Instead of simple Moving Averages (which lag significantly), we use Volatility Breakouts.
We calculate the ATR (Average True Range) of Nifty. If price moves X * ATR away from the mean, it indicates a structural shift in supply/demand—a trend effectively "breaking out" of its noise band.
Filter Mechanism: The "Chop" Filter
The killer of all trend strategies is the sideways market (whipsaws). To mitigate this, we use an ADX (Average Directional Index) filter.
If ADX < 20: Stay Cash. Do not trade.
This simple rule keeps us out of the market during low-momentum phases, saving substantial capital.
Exit Strategy: Trailing Stop
We never use a fixed target. A trend can go on for days, weeks, or months. We use an "Adaptive Trailing Stop" based on volatility. As the trend strengthens, the stop tightens. This allows us to ride the massive 1000+ point moves in Bank Nifty that happen 3-4 times a year.
Results
This approach captures the "Fat Tails" of the return distribution. We endure many small losses (whipsaws) to ensure we are positioned for the massive outlier events that generate the bulk of the year's P&L.
