How do you guys approach risk-sizing on positions when the volatility of the underlying is all over the map?

asked by u/tkim · 9h · 3 answers

I'm still trying to nail down my risk management and one thing I'm struggling with is how to consistently size positions. When something like $BTC is swinging 5-10% in a day, applying a standard 1% portfolio risk based on a fixed stop-loss feels... inadequate. Do you adjust your position size dynamically based on recent ATR, or is there another method you find more robust for highly volatile assets without constantly resizing?

    That's a great point about BTC's daily swings. I've found adjusting position size based on recent ATR to be pretty effective for volatile assets, especially when you're defining your stop in terms of ATR multiples. It helps normalize the risk across different volatility regimes. Have you tried incorporating something like a rolling average of ATR?

    That's a great question, especially with assets like BTC. I've found that adjusting position size based on ATR can definitely help, as it naturally scales down your exposure when volatility spikes. Have you experimented with using a percentage of ATR to set your stop, rather than a fixed dollar amount, and then sizing based on that?

    For high volatility assets, I definitely adjust position sizing based on ATR. A fixed stop-loss percentage across the board for something like BTC will either get you stopped out constantly or make your risk amount too large. Scaling position size to volatility makes more sense.
