Zacks upgrades INFN to Buy

Through my Fidelity account this morning:

Zacks Investment Research, Inc. upgrades INFINERA CORPORATION from HOLD to BUY.

On October 26, 2015 Zacks Investment Research, Inc. upgraded INFINERA CORPORATION (INFN) from HOLD to BUY.

I could not find this information through any public channel. I suppose these upgrades and downgrades are made available after they are issued to Zacks subscribers first, which only makes sense.

Look for the upgrade tomorrow morning or after after earnings are announced tonight.
