UBS has named the real estate investment trusts AvalonBay Communities Inc AVB, Federal Realty Investment Trust FRT and Kilroy Realty Corp KRC as top picks. "Post 3Q, we are now more positive on the multifamily and shopping center REITs and recommend investors Overweight both subsectors," UBS said in a Thursday note. Despite lowering the sub-sector view on office REITs to Market-weight, given less positive near-term catalysts, UBS said it continues to maintain Kilroy as a top pick.
