Eoin Treacy's view

S&P 500 Diversified Financials have experienced the deepest pullback since at least 2011 and its rally from the August low has been modest at best. A sustained move back above 500 would be required to signal a return to demand dominance. 

KBW Regional Banks Index retraced more than half its August decline over the last couple of weeks but encountered resistance this week in the region of the 200-day MA; posting a large downside weekly key reversal. Downside follow through next week would further emphasise supply dominance at progressively lower levels. A sustained move above the MA will be required question potential for a further test of underlying trading. 

Euro STOXX Banks Index will need to find support above or in the region of the late August low to indicate demand is returning at progressively higher levels. 

The FTSE-350 Bank Index is still deeply oversold relative to the trend mean but the low near 3750 will need to hold if support building is to be given the benefit of the doubt. 

The relative weakness of the financial sector, globally, represents a headwind for the wider market.
