Hilarious http://www.bloomberg.com/apps/news?pid=20601109&sid=aPxYA4rjLD18&pos=15 Feb. 5 (Bloomberg) -- At Barclays Capital, Piigs wonât fly. The securities unit of London-based Barclays Plc told analysts yesterday not to use the acronym for Portugal, Italy, Ireland, Greece and Spain in notes to clients, according to a memo obtained by Bloomberg News. The mandate from Valerie Monchi was sent to research staff. The Piigs nickname has grown increasingly popular in the last month as investors dumped assets in the euro zoneâs smaller economies on concern the countries will struggle to control budget deficits. Stocks in Spain and Portugal slumped the most since 2008 yesterday, while yields on Greeceâs 10-year bonds and Portugalâs 2-year securities have jumped to the highest levels against German bunds since the late 1990s.
