New York Community Bancorp (NYCB) has seen its shares plummet since reporting a surprising fourth quarter loss and slashing its dividend. The pressure only mounted after Moody's downgraded the company's credit rating to junk. The bank named a new chairman and has taken other steps to assure investors, but it is raising some concern about the health of regional banks. NYCB's woes stem, in part, from its decision to acquire some of the assets of Signature Bank, which failed during last year's regional banking crisis. David Smith, U.S. Banks Analyst at Autonomous Research, and Christopher Marinac , Director of Research at Janney Montgomery Scott joined Yahoo Finance Live to weigh in on the bank's turmoil. Marinac calls NYCB "a real player" in the multifamily home space. He points out that the company had been going through a "business model change" and that "what you want to see them do is really diversify their book." However, he notes that none of the changes at the bank "can happen fast enough for investors that are worried about the stock." Overall, Marinac believes that part of the problem for New York Community Bancorp was that it was trying to get ahead of changes to capital requirement rules, a process that he describes as "painful" for the company. He says the market was shocked by the earnings announcement which caused a "loss of confidence." When it comes to concerns about what NYCB's woes could mean for the regional banking sector as a whole, Smith believes that "These issues are contained to NYCB. These are issues that are pretty idiosyncratic to the bank with its transition from being a smaller, regional bank into a larger one that's under stricter regulatory supervision." He goes on to add that NYCB's issues are more of "earnings rather than viability" nature.
