Oerlikon stock falls after guidance cut and H1 EBITDA miss

** Swiss industrial group Oerlikon's OERL shares drop 11.2%, to the bottom of the Swiss mid-cap index (.SMIM), as the company cut its full-year outlook and reported mixed second-quarter results

** The company revised its full-year outlook, citing weak industrial demand and trade tariff burdens

** Oerlikon now expects for full year flat to slightly lower sales and an operational EBITDA margin of 17.0%-17.5%, down from prior estimates

** Up to the previous session's close, shares were up 9.9%​ YTD
