* These new industry classifications are based on firm
pairwise similarity scores from text analysis of firm 10K product
descriptions. Competitors are firm centric with each firm having its own
distinct set of competitors - analogous to networks or a
"Facebook" circle of friends. These new industry classifications are
updated annually and offer more research flexibility, and are also more
informative, than FIC (fixed industry) classifications such as SIC, NAICS,
and the 10-K based FIC classifications below. Our research shows they
sharply improve upon SIC and NAICS codes in explaining many different firm
specific decisions, including firm profitability, Tobins Q and dividends.
These benefits are outlined in Hoberg and Phillips (2010, 2016), with

* HHI Concentration metrics and Total Similarity data is
available based on TNIC Industries.
* Product
Market Fluidity data assesses the degree of competitive threat and product
market change surrounding a firm, and is based on Hoberg, Phillips and
Prabhala (2014).
* Vertical
TNIC data is comprised of two key databases, and is based on Fresard,
Hoberg, and Phillips (2020). The first is a firm-year panel
indicating the extent to which firms are vertically integrated. The second
is a firm-pair-year database indicating the potential for vertical
relatedness for every pair of firms in every year.
* Scope
data is comprised of two key databases, and is based on Hoberg, and Phillips (2024, Journal of Finance forthcoming).
The first is a firm-year panel indicating the scope of each firm (number of product markets it operates in). The second
is a firm-market-year database indicating the specific text-based markets each frim operates in for each year.
