ABN Amro at 1-month low after buyback misses expectations

** Shares in ABN Amro ABN fall around 7% to their lowest price since early July after the Dutch lender announced lower-than-expected share buyback

** ABN Amro said on Wednesday it would buy back shares worth 250 million euros ($289.63 million) as its second-quarter net profit narrowly beat market expectations

** J.P.Morgan analysts say the buyback was below the 517 million euros seen in consensus, which might be connected to increase in capital requirements

** Still, they add it was surprising considering the maximum distributable amount (MDA) buffer the bank has amassed

** "Q2 revenue trends disappointed and the SBB announcement is below consensus... We expect some weakness in the shares on the back of this," RBC Capital Markets analysts add

** Up to the previous session's close, shares were up 67.4%​ YTD
