Cyprus’s largest lender returned to the Nicosia and Athens stock markets Tuesday after a 21-month absence following a banking crisis that brought the island’s economy to its knees. But early trades in Bank of Cyprus shares ensured a bumpy ride for the return of the country’s top financial company, AFP said. In early trading, BoC was down 8.75% at 21.9 euro cents on the Cyprus Stock Exchange. Some 8.9b BoC shares resumed trading on the CSE and the Athens bourse priced at 24 euro cents. When it ceased trading on March 15, 2013, amid an international bailout crisis, the share price closed at 21 cents.
