** Shares in German specialty chemical maker Symrise SY1G.DE rise 6.2%, to its highest since late October, following portfolio shift announcements and share buyback
** Symrise plans to divest its terpenes business and invest in subsidiary Swedencare
** J.P.Morgan says that some impairment for the business should be unsurprising given its financial performance, and exit talks should reassure that a portfolio shift is progressing
** The group will book a 295 million euros ($344 million) in non-cash impairments for terpenes and Swedencare
** The company also plans to buy back 400 mln euros worth of share from February 1
** JPM expects 2% to 3% accretion to EPS from the buyback and sees it as a sensible use of the balance sheet
** The stock is heading for its best day in 1-1/2 month short of 2 years if gains hold
