BUZZ-TalkTalk: near top of FTSE 250 after Macquarie upgrade

** TalkTalk up 9.5 pct, second-top riser on FTSE 250, after Macquarie raises rating to "outperform" from "neutral‍"

** Upgrade follows the "emergency capital increase" and better-than-expected broadband addition outlook, says Macquarie analyst Guy Peddy ** Last month co said it would raise up to 200 mln pounds ($278 mln) in a placing ** Co also announced acceleration in its net adds ​

** There is limited risk of overbuild in UK fibre, as there is low level of installed base; expects co to add 90k net broadband additions in Q4 2017/2018, equivalent to a 49 pct share, adds Peddy

** "TalkTalk is trading at an attractive valuation given the broadband growth outlook" - Peddy
