A caffeine buzz for the books
The last 12 months were a crazy year for coffee prices, and this had a heavy impact on reliant businesses. The price of coffee hit 34-year historic highs early on, due to lower-than-normal supply and rising demand. Cooler temperatures in coffee producing countries were partially to blame for the low supply.

Along for the ride were coffee companies like Coffee Holding, Green Mountain Coffee Roasters (Nasdaq: GMCR), Starbucks (Nasdaq: SBUX), Caribou Coffee (Nasdaq: CBOU), and Dunkin' Brands (Nasdaq: DNKN), all of which were faced with the decision to pass on the price changes to customers or absorb them themselves.

A match made in java-dise?
Coffee Holding had an especially volatile year, currently up 118% after an initial 733% rise. The company is closely linked to Green Mountain Coffee Roasters, with the Vermont-based coffee brewer accounting for nearly 53% of Coffee Holding's revenue.

The company's relationship with Green Mountain is likely what helped spur Coffee Holding's spike beyond what coffee itself was doing. As Wall Street talked up Green Mountain, investors bought up Coffee Holding. And so it went until the stock price imploded with multiples twice what they are now, dropping nearly 62% in the last few weeks of September.

The stock price crept back up a little bit, but the final blow came in November, when David Einhorn called accounting shenanigans on Green Mountain. As you might expect at this point, Coffee Holding's stock fell another 28% that month. Ouch.

The volatility of this stock is only amplified by the large percentage of shares held short. This contrasts to a huge percentage of shares held by insiders. This appears to have a ying-yang effect for shareholders, with prices swinging wildly up or down.
