From Goldman Sachs:
Tracking recent sector performance: Since the beginning of August, Australian banks are down 13.9% and have underperformed the ASX200 by 2.9%. As a result, the premium to fundamental valuations (and historical averages), which the sector has enjoyed on many measures since 2013, has more than dissipated.
Valuation drivers still intact, in our view: We think yield appeal, earnings defensiveness and sustainable returns have been the biggest drivers of sector outperformance in recent years. Apart from more definitive signs through the August reporting season that the credit cycle has troughed, we do not believe there has been any material shift in these underlying drivers.
