NEW YORK ( TheStreet) -- Over the past month, the six biggest bank stocks have lost an average of 13%, seemingly on fears of what effect new, yet-to-be-determined regulations will have on their profitability.
Wells Fargo (WFC - Get Report) shares have lost the least value, with a decline of 8% since Jan. 8, closing at $26.43 on Monday. Morgan Stanley (MS - Get Report) was the loss leader, with an 18% decline, dropping to $26.60 by Monday's close. Citigroup (C - Get Report), Goldman Sachs (GS - Get Report), Bank of America (BAC - Get Report) and JPMorgan Chase (JPM - Get Report) were somewhere in between, all with double-digit declines.
The sell-off gained momentum roughly around the time JPMorgan announced fourth-quarter results on Jan. 15. Revenue was disappointing, and management comments about the road ahead weren't as sunny as some had hoped.
