The index of leading economic indicators jumped to 50.0 in October from a revised reading of 25.0 in September, matching market expectations, preliminary data from the Cabinet Office showed. A reading above 50 points to economic expansion over the subsequent six months, while figures below 50 suggest a contraction. The leading index is based on 12 indicators, of which data for 10 were available for the preliminary reading, with five pointing to expansion and five suggesting contraction. The coincident index, which measures the state of the economy at the time, surged to 77.8 from 50.0 in September, in line with market consensus forecast. The coincident index is based on 11 indicators, of which data for nine were available for the preliminary reading, with seven pointing to expansion and two suggesting contraction. The lagging index, which reflects economic conditions three months before, dropped to zero from 58.3 in the previous month. The figure was based on four of six indicators used to compute the index, with all four pointing to a contraction.
