** Italian grid operator Terna TRN.MI suddenly spikes as a
Bloomberg headline saying "TERNA ENERGY IS SAID TO EVALUATE
OPTIONS AMID TAKEOVER INTEREST" circulates among traders
** The spike in Milan-listed Terna quickly fizzles out as it
becomes clear the takeover report is about Greek renewable
energy firm Terna Energy TENr.AT
** One London trader says a human mistake may explain the spike
in the wrong Terna, but "algos" may have contributed too
** By 1212 GMT, Milan-listed Terna down 0.5% having jumped 3.5
pct points in less than a minute after the Bloomberg headline
hit. Athens-listed Terna Energy up 3%, spiking after the report
