Choosing Market Models for Index Straddle Backtests

Summary

The document asks how to choose a simplified framework for simulating stock markets, including which stylized facts matter in different settings. It also raises a specific application: evaluating a strategy that holds long straddles on a broad index and rolls them monthly, with the aim of capturing return volatility.

No model recommendation, analysis, or empirical evidence is provided; the text is a request for references and suggestions. It therefore identifies the modeling questions and strategy being considered but does not resolve how to represent volatility, options, or index behavior. Any backtest would need to select and justify those assumptions separately.

Key ideas

• The author seeks references on stylized facts used in stock market simulation.
• The relevance of a stylized fact may depend on the modeling task.
• The proposed strategy rolls long index straddles monthly to capture return volatility.
• The document poses these questions but does not recommend a model or report results.

Does anyone know a reference where one can read up on different aspects of modelling when simulating the stock market? i.e what is known as "stylized facts" and which of these fact that are more interesting then others in different situations.

Moreover I am looking to evaluate an options strategy on a entire index if anyone has some suggestions on which model to pick in that situation. I wanna roll monthly long straddles and so I wanna capture volatility of returns.
