** Shares in Nordnet SAVE fall about 5% after the Swedish online broker reported second-quarter adjusted earnings slightly below market expectations

** J.P.Morgan also points to a SEK 18 mln negative one-off impact in reported revenues due to an admin error

** "We expect that the slight miss and the loss related to the admin mistake might be poorly received today and lead to a negative share price reaction," the brokerage says

** JPM says the 2% miss on Q3 profit of SEK 904 million ($96.01 million) was driven by weaker net commission income
