Volatility-Adjusted Sizing for Micro Treasury Futures

Summary

The document asks how to size 10-year Treasury micro futures against a full-sized 10-year note futures contract when adjusting exposure for volatility. It reports an estimated volatility ratio of 5.125 between the micro and full-sized contracts and seeks the micro-contract count that would match one full-sized contract’s volatility-adjusted exposure.

No calculation, answer, or method for estimating the ratio is supplied. In particular, the question does not explain the lookback period, return definition, or whether contract value and tick economics have already been incorporated. Those choices matter: matching volatility-based exposure requires comparing risk per contract on a consistent basis, then scaling the position accordingly. The stated ratio alone may support a simple proportional calculation only if it already represents comparable per-contract risk; the document leaves that assumption unclear.

Key ideas

• The question concerns matching the risk exposure of micro and full-sized 10-year Treasury futures.
• It gives a volatility ratio of 5.125 for the micro relative to the full-sized contract.
• A volatility-based contract count depends on comparable per-contract risk estimates.
• The document does not specify the estimation period or provide the requested calculation.

I want to decrease my exposure to a 10-year note futures by using 10-year micro futures after volatility-adjusting them. I've calculated that the difference in volatility in the micro has 5.125x the volatility of a full-sized.

How many micros would I need to have the same exposure as a full-sized contract after volatility-adjusting them?
