** Bernstein upgrades French geoscience firm Viridien VIRI.PA to "outperform" from "market-perform", citing overlooked catalysts in the oil and gas sector's digitalization
** The upgrade follows a recent share price fall, which the brokerage views as a buying opportunity created by an overreaction to macro fears of oil oversupply
** Bernstein sees Viridien as best-placed to gain from the oil and gas industry's accelerating adoption of cloud and artificial intelligence (AI) technologies
** "Macro fears may be masking new catalysts," the brokerage says, keeping its price target unchanged at EUR 117
** Brokerage sees potential for positive surprises in the fourth quarter
** Out of 6 analysts that cover Viridien, four rate the stock "strong buy" or "buy" and two rate "hold" - data compiled by LSEG
