Continuing my quantitative analysis system that applies the concepts of implied volatility in options markets to the NBA, by extracting a player sigma directly from the Over/Under lines of bookmakers to detect statistical mispricing.

Here is the end-to-end data pipeline collecting player stats (NBA API), O/U odds (Odds API) and matchup data, to calculate realized volatility (rolling STD of performances) and implied volatility (reversal of bookmaker pricing) in parallel, then identify exploitable IV/RV spreads.

Inspired by the analysis of aurelius.v.1, I also integrated an analysis of the feeling opposing fans and the media.

Being an observer of this sport since the 2010s, the criteria that made a player good or that a team was good at the time are no longer the same as today.

I am thinking in particular of V. Wembanyama who is a revolution at his post.

We can also ask ourselves questions about the impact of social networks then and now. For example, one might ask whether Mr. Jordan would have been even more popular today than 30 years ago? What impact would his communication have had today on the feeling of the public and the media?

The next step for me in this project will be to find an advantage.
A system that extracts the implied volatility from the O/U NBA lines to detect discrepancies with players' historical realized volatility, amplified by a social sentiment analysis that anticipates mispricings before they form in the line.

I look forward to your observations and comments!
Good day everyone!

Thank you for sharing! Eager to see more in the context of your backtests, covariance structures, and so on, there are a lot of sources of data and methods to construct sharp odds to quote prices too, curious of implications here in optimizing market making too
