Cheap Convexity: Using Helium to Buy Options

Helium’s cheap convexity finds options that have high convexity and low carry cost.

How Does it Work?

Every day, Helium looks through the options universe to find calls, puts, and debit spreads that best satisfy a balanced combination of:

  • High Convexity (gamma): You can think of this as optimizing for potential acceleration in the value of the option, relative to the price of the underlying asset.

  • Small Time Decay (theta): Helium tries to minimize the carrying-cost of being long options. Theta represents the daily money lost by holding an option if nothing else happens.

  • High Expected Value (expected value): Helium tries to maximize the expected terminal value of each position, as determined by market prices & Black-Scholes implied probabilities.

  • Helium Uncertainty > Market Uncertainty: By comparing market uncertainty to Helium uncertainty, we can seek out underlyings with potentially under-priced risk.

  • Low Price: Looking for cheap convexity means optimizing for cheaper options/spreads (less possible max loss).

  • AI Price Forecasts: Using meta machine learning price forecasts, Helium weights call options higher on bullish stocks (long delta) and weighs put options higher on bearish stocks (short delta).

  • Low Implied Volatility Rank: (IVR) Helium is looking for assets with lower IV (relative to yearly highs and lows) in order to take advantage of options priced relatively cheaply.

  • One Click Trade Execution: Automatic limit order algorithm to get filled at attractive prices

Trading Helium’s Cheap Convexity

To find the options, click the purple “Cheap Convexity” buttons on Long Call Forecasts, Long Put Forecasts, or Long Volatility Forecasts. For some stocks, Helium also has backtested options trading strategies

For each potential trade, Helium will link to the potential call/put option on Yahoo Finance, as well as show the estimated probability of success, cost, expected value (for spreads), and risk exposure graphs to delta (movement of the underlying), vega (changes in volatility), and theta (carry cost).

These trades have not been backtested, but are updated daily on potentially attractive market prices, predominantly the gamma/theta ratio (eg trying to maximize the ratio of convexity to carry cost).
