Tech Pulse

The Tech Pulse Index is an index of coincident indicators of activity in the U.S.
information technology sector. It can be interpreted as a summary statistic that
tracks the health of the tech sector in a timely manner. The indicators used to
compute the index are investment in IT goods, consumption of personal computers
and software, employment in the IT sector, as well as industrial production of and
shipments by the technology sector. The index extracts the common trend that
drives these series.

Announcements
• The econometric model used to construct the Tech Pulse index is re-estimated
every month. Consequently, every month the whole historical time-series of
the index is revised.
• The econometric specification of the model underlying the index as well as the
source data have changed substantially compared to the versions of the index
released before August 2008. Therefore, the current version of the Tech Pulse
index is not directly comparable to previous versions of the index published
before December 2008.
