Index Rebal/Special Situations, Quiddity Advisors

Janaghan Jeyakumar, CFA

Equity Analyst with 10+ years experience in fundamental and event-driven research.

On Smartkarma, I mainly publish insights on index flow events. This includes predicting regular and intra-review index changes and formulating market-neutral trading strategies based on flow catalysts. I also cover special situations such as mergers & acquisitions, equity offerings, buybacks, and other corporate restructuring events.
