The Social Media in the City report we launched this week looks at the comparative social media performance of the FTSE 100 companies. But we also looked at how FTSE 100 sectors with 3 or more companies perform: to see how average sector performances compare; and to highlight any major variations within sector.

There are some surprises.

The table below, ranked based on the average Social Performance Index (SPI) scores, shows that seven sectors score above average (100). They are not necessarily the most obvious, consumer-facing candidates. Shell’s and AstraZeneca’s individual strong performances helped their respective sector groups, with Pharmaceuticals & Biotechnology and Oil & Gas Production sectors commanding the two highest average SPI scores. Unsurprisingly, General and Food & Drug Retailers take the 3rd and 4th positions and Media the 5th, but Aerospace & Defence in 6th place is a surprise above Banks, Food Producers and Gas, Water & Multiutilities.

The chart below maps two general factors that contribute towards this performance – the Awareness Quotient (a measure of status) and the Engagement Quotient (a measure of participation and interaction). A low EQ combined with a high AQ suggests the PRINT™ score is driven disproportionately by scale rather than social engagement.

Awareness Quotient (AQ) bundles the PRINT™ attributes Popularity and Network and tends to favour larger, more established companies with larger communications spends. Engagement Quotient (EQ) bundles the Receptiveness, Interaction and Trust attributes.

The full study data allow us to analyse each sector in much more detail, and we’ll be highlighting some of these over the coming days.
