In the United Kingdom, the Small Business Sentiment measures measures the expectations of business conditions for companies with up to 199 employees. The Questionnaire accesses the overall sentiment regarding general and export business situation, investment, capacity, order books, employment, output, stocks, prices competitiveness regarding domestic, EU and non-EU markets and innovation and training. For each assessment is computed a sub-index as the percentage of positive answers minus the percentage of negative answers. The composite index is then computed as the weighted average of the sub-indices. An Optimism Index of +100 indicates that all survey respondents are much more confident about future prospects, while -100 suggests that all survey respondents are much less confident about future prospects. An index level of 0 indicates neutrality.
