Unlike other public companies in the US, most banks with market caps <$100M do not submit their financial statements to the SEC. Instead they submit their statements to their regulatory body, i.e. OTS, FDIC, Fed, etc. Here is a useful link which distills the data so you don't have to go through hundreds of pages of regulatory info. http://www.faqs.org/banks/
I did a CAPS screen for banks with P/E < 10, P/B < 1, LTD/E < 2, Revenue Growth > -1, Earnings Growth > -1, and ROE > 8. However the CAPS data for these banks are not current, so these companies have to be cross-referenced to the source above.
I started to look these up because banking is a pretty stable business when it's done well, yet a lot of these were crushed and have not rebounded nearly as well as the overall market. Here are a few of the banks I've looked up so far:
Name (Ticker) Market Cap Assets Tier 1 Tier 2 Income Charge-Off
Saehan Bank CA (SAEB) $6.7M $843M $81M $10M -$10M $15.9M
Home Valley Bank OR (HVYB) $3.5M $245M $21M $2.5M $1M $0.6M
Granite Bank CA (GBSI) $2.7M $141M $16M $1.7M $.2M $2.3M
First Bank of Delaware (FBOD) $17M $116M $39M $1.1M $4.9M $3.8M
FBOD looks interesting - they are one of the least leveraged banks I've ever seen, yet have very strong earnings despite pretty large chargeoffs. HVYB may also be pretty underpriced. Of course the California banks are more troubled, yet they may still turn out to be good deals.
More to come over the next few days.
