What: Shares of Fossil Group (NASDAQ:FOSL) fell by as much as a fifth on Wednesday after the fashion accessories company announced fourth-quarter results and guidance for the current quarter and the full year 2015 -- all of which fell short of Wall Street's expectations. By 2 p.m., shares were down 18% from the previous close.

So what: Fossil Group's fourth quarter is in the bag, so it matters only inasmuch as it is predictive of future results. In any event, as the following table demonstrates, the "miss" on fourth-quarter earnings per share (~5%) is trivial compared to the shortfall between the company's future guidance and Wall Street estimates:

Where does this shortfall stem from? The company is blaming the impact of foreign exchange translation and restructuring charges. For the full year 2015, it expects the former to reduce earnings per share by $1.20, on the assumption that "current foreign currency exchange rates that affect the Company's financial results remaining at prevailing levels."

Now what: Jefferies analyst Randal Konik sees an "opportunity to initiate LT [long-term] positions in the stock today." That's very plausible, if the market is mainly reacting to the company's forecast of foreign exchange effects. Currency effects do not determine a company's long-term earnings power or, by extension, its intrinsic value. Instead, in considering whether to buy the shares, patient investors ought to be trying to assess the potential impact of wearables technology on Fossil Group's watch franchise.
