The alert at 0724 GMT, "ERSTE SAYS UPS UNIPETROL<UNPEsp.PR> TO 'BUY' FROM 'SELL', LOWERS TARGET PRICE TO CZK 251", was based on a recommendation first issued by the bank on July 10.
The recommendation was mentioned in Erste's September report on central and east European oil and gas shares, which was received by Reuters on Monday.
