Bloomberg Second Measure
Bloomberg Second Measure provides a US credit and debit card panel comprising between 4-8MM users, with history going back to 2013. Second Measure sources this data from similar entities to those of competing Credit/Debit Card resellers, though the underlying tagging, panel selection, normalization and error correction approaches can cause significant differences from merchant-to-merchant vs its peers. The BBG SECM panel is mapped to both merchants as well as tickers. We will typically de-duplicate on our side to ensure a company’s feed is not counted twice during sector or sub-sector aggregations. The schema is simple, with four distinct indices to track dollar spend, transactions, unique users and average transaction price. Second Measure uses only one normalization method, whose details are kept proprietary but is philosophically pegged to the number of active cards in the panel, as opposed to the “% of total panel spend” approach.
