Based in New York, Montana will report to Joshua Friedberg, head of trading, Americas. 

He joins from Merrill Lynch, where he spent 25 years in New York and London - most recently as a managing director in charge of non-dollar sales and trading. 

Deutsche Asset & Wealth Management said the appointment of Montana is part of the firm's initiative to boost its equities investment offering. Portfolio manager Richard Glass, for example, joined in August as US head of small- and mid-cap value equities in New York, along with Richard Hanlon and Mary Schafer. Additionally, Sean Taylor started as head of emerging market equities, based in London.
