** Shares in Aegon AEGN.AS fall around 4% to their lowest price since mid-December, after the insurance group's second-half results "messy" beat
** Aegon's second-half operating capital generation (OCG) came in at 711 million euros ($839.12 million), above 654 million euros in company-compiled consensus
** However, analysts at J.P. Morgan and traders from other brokerages call the results "messy" as they see OCG benefiting from one-off favourable items
** "Aegon has reported a typically messy set of results... OCG is below consensus if we strip out one-offs", says J.P. Morgan, adding that the end-year update didn't include new information on UK business strategic review
** Up to the previous session's close, shares were down 0.4% YTD
