CommonWealth REIT (NYSE: CWH) was upgraded by analysts at Stifel Nicolaus from a “sell” rating to a “sell” rating in a research report issued to clients and investors on Thursday.

The analysts wrote, “We think Corvex & Related (C&R) is actively trying to complete due diligence and obtain financing in order to provide a non-contingent tender offer for Commonwealth shares. As a result of the recent dilutive equity offering, we expect this offer to be in the range of $20-$25/sh. … Meanwhile we think shareholders who bought recently at $19/sh are very willing to reduce their positions as they weigh the likelihood of C&R being successful and acquiring CWH or RMR being successful in protecting its fee stream; with RMR remaining in place, we believe the result would be a $15/share price. Hence our downgrade.”
