As previously reported, Morgan Stanley analyst Vikram Malhotra downgraded SL Green Realty (SLG) and Boston Properties (BXP), both to Underweight from Equal Weight, as he remains cautious on NYC office REITs. While acknowledging that the current 25% discount to net asset value may make NYC office REITs attractive, his deep dive into 200 NYC deals showed him that this metric could be misleading and in fact REITs are pricing in optimistic long-term growth based on cash flow metrics. For SL Green, Malhotra sees growing execution risks that could drive lower than anticipated cash flow growth. For Boston Properties, he believes the REIT's defensive attributes are "more than priced in" to its share price. Malhotra also upgraded Paramount Group (PGRE) to Equal Weight from Underweight, as previously reported, telling investors that he now thinks modest expirations and strong operating income growth are balanced by valuation. Malhotra lowered his price target on SL Green shares to $85.50 from $97, cut his target on Boston to $116 from $130, raised his target on Paramount to $15 from $13.25, lowered his target on Vornado (VNO) to $72 from $76 and edged up his target on Columbia Property (CXP) to $22.50 from $21.25.
