Noting that Chicago Bridge & Iron shares have declined 20% this week, versus a 2% pullback for its close peer group, KeyBanc analyst Tahira Afzal said she's surprised by the extent of the stock's underperformance, highlighting that an upcoming court decision on the scope of the contested Westinghouse claim, which remains likely in June, remains a potential positive catalyst. The analyst, who views CBI's recent moves to reduce debt and transition to a new CEO as positives, sees the stock as fairly valued and keeps a Sector Weight rating on the shares.
