While it's been a rough few months for large-cap stocks like Amazon (Nasdaq: AMZN), Berkshire Hathaway (NYSE: BRK-A) (NYSE: BRK-B), Cisco (NYSE: CSCO) and Google (Nasdaq: GOOG), it's been an even rougher market for some small-cap stocks. If you don't follow small caps, you're not alone -- 4,500 small-cap stocks receive no coverage from Wall Street analysts. Is it time for investors to buck the trend and think small? In this installment of "Fool Video," Motley Fool analyst Tim Hanson gives his take on some quality large caps, and explains why he's bullish on small caps like Willamette Valley Vineyards (Nasdaq: WVVI) and Portfolio Recovery Associates (Nasdaq: PRAA).
