PDI Transaction Data Feed Updated

PDI has released a restatement of its Transaction Data Feed that reapplies data-quality improvements and
an expanded product catalog across the full transaction history. These are quality and categorization
refinements — not a change in real-world market activity — but historical figures may shift compared with
a prior version.

Suggested action:
If your research uses this data, we recommend refreshing to the current version so your history reflects
the latest quality improvements and product categorization.
