Stay away from small-cap bank stocks.

It was nearly 18 months ago now that Tim first dished out that advice. Though those stocks looked cheap at the time, writedowns were happening across the industry, making financial institutions nearly impossible to value. On top of that, the economy was showing signs of sputtering with no resolution in sight.

Not much has changed
It's hard to believe, but the current economic downturn is nearly two years old now -- and it's gone from bad to worse. Notwithstanding the recent rising tide in the market, stocks have gotten "cheaper," writedowns have gotten bigger, and the federal government is throwing Hail Mary passes in the hopes of averting further crisis.

And while big financials such as Lehman, AIG , Fannie (NYSE: FNM) and Freddie , and Goldman Sachs (NYSE: GS) have dominated the headlines, small financials have been hit just as hard. In fact, it's gotten so bad that former mid-cap banks are now de facto small caps: Regions Financial (NYSE: RF) and Huntington Bancshares (Nasdaq: HBAN) have lost 75% or more of their value since this crisis began in late 2007!

All of this is to say, it's still not time to start buying small-cap banks.

It may, however, be time to start looking hard at something a little off the beaten path: small-cap value.

What's the difference?
Small-cap value and small-cap banks often get conflated -- and for good reason. As Brian noted last year, the Vanguard Small-Cap Value ETF (VBR), like most small-cap value indexes, has substantial exposure to small banks. For the quarter ended March 31, small financial services companies accounted for 34% of the fund's holdings.

But although small-cap value stocks have been the worst performers in 2009, Russell Investments recently released a report suggesting that "they could emerge as the frontrunners if the economy stages a recovery."

So while you don't want to buy small-cap banks, you do want to buy small-cap value net of banks because, as Mark Hulbert noted in a New York Times article at the end of 2008, these historical outperformers "produce their most explosive gains right at the start of a bull market."

But let us be clear
Neither we nor Mr. Hulbert are predicting that we're at the start of a bull market. Rather, we're noting that:

And thus: Now is a good time to start buying small-cap exposure for the long term.

After all, a little exposure to this market segment gives you the chance to take advantage of this historical trend and puts you in the position for significant outperformance whenever this bear market turns for good. Continued...
