The FTSE 100 was little changed on Tuesday and underperformed other European markets as losses in defensive stocks offset gains in energy shares, extending a cautious start to the week. AstraZeneca fell around 1%, GSK dropped more than 1.5% and Unilever declined about 0.6%, while Shell rose 1.4% and BP gained 1.8%. Earlier support for the oil majors had come from supply concerns linked to a possible US-Iran arrangement and the Strait of Hormuz, but renewed hopes for a deal after Pakistan signaled the two sides could be nearing an agreement eased some of those worries and trimmed the recent crude rally. InterContinental Hotels Group fell more than 2% despite first-half profit above expectations, Bellway warned that the near-term outlook remained uncertain even after beating forecasts for home completions and housing revenue, and UK consumer indicators were mixed, with July retail sales up 1.3% year on year and Barclays reporting 2% spending growth, its strongest this year.
