SpiderRock was recently featured in a DataDrivenInvestor article, How to Break Down Market Stress with Options Data in Python, which explores how options data can be used to move beyond a single volatility reading and pinpoint where market stress is showing up.

The article presents a Python framework for analyzing SPY market stress. It combines live Nations Indexes values, calculated and distributed by SpiderRock through MLink, with historical index and SPY price data. It converts five measures (volatility, call demand, put demand, skew, and tail-risk pricing) into historical percentiles, making it easier to compare the signals and tell different market environments apart.

Rather than treating volatility as a one-dimensional fear gauge, the framework shows how similar volatility levels can mask very different options-market structures, whether driven by put buying, tail hedging, or call demand. The result is a more structured way to interpret what the options market is pricing and how stress builds or broadens beneath the surface.
