Although we don't believe in timing the market or panicking over market movements, we do like to keep an eye on big changes -- just in case they're material to our investing thesis.

What: Shares of organic light-emitting diode specialist Universal Display (Nasdaq: PANL) were projecting weakness today, falling as much as 13% in intraday trading after some sour comments from a Wall Street analyst.

So what: Canaccord Genuity's Jonathan Dorsheimer stepped back his price target for Universal Display's stock, from $40 to $35. The change was due in large part to a change in estimates for the company's licensing agreement with a unit of Samsung Electronics. Dorsheimer had previously expected that the opportunity was worth $350 million to $375 million, but now sees it in a range of $290 million to $300 million. The analyst also said that there is a "lack of positive near-term catalysts" for Universal and that the excitement from the upcoming Consumer Electronics Show is likely already priced in.

Now what: As the stock's price action makes obvious, investors are not happy about Dorsheimer's less-sanguine take. To be sure, the analyst's reevaluation could be a good reason for Universal Display bulls to revisit their views on the stock and assess whether there's still a good opportunity there. However, it's also important to keep in mind that these are simply the views of one person and don't represent a definitive bottom line on the stock or the company. So while investors shouldn't ignore the Canaccord report, it'd likely be foolish (little "f"!) to sell only because of that one view.
