Method
The 5 event driven ETFs ETFIQ measures, of which 5 publish net assets. Across the funds listed here correlation with the S&P 500 runs from -0.0 to 0.4. Size is not a measure of how much a fund diversifies. The correlation column is. The ranking is the published field sorted, nothing else: no scoring, no weighting and no view on any fund. Every fund ETFIQ covers in this category is eligible, including funds that have closed, because leaving them out would flatter the category.
