Covering the markets right now is almost as tiring as trading in them. Japan rallied sharply and that was supposed to be giving a huge boost to stocks this morning. A downgrade of Portugal and an inflated wholesale inflation reading did not help matters. The reality is that headlines of statements from government officials from U.S. and Europe tended to move the markets more than fundamentals. Then the media sensationalism with urgency behind every single statement made for more directional changes than could be easily counted.

Here were today's unofficial closing bell levels:

Dow Jones 11,613.30 -242.12 (-2.04%)
S&P 500 1,256.88 -24.99 (-1.95%)
Nasdaq 2,616.82 -50.51 (-1.89%)

When a new technology is offered to investors, the cautious in the crowd tend to stand back and await developments. When established firms begin to use that technology, it's time to pay close attention. There is an outfit in Ewing, New Jersey, that has been a pioneer in the commercialization of a special kind of light emitting diode. Now, some of the big consumer electronics players are beginning to show a serious interest.

Universal Display Corporation (NASDAQ: PANL) develops and commercializes organic light emitting diode (OLED) technologies and materials for use in flat panel displays, solid-state lighting products, cellphones and other opto-electronic devices. OLED screens use organic semiconductor materials to sharpen image and color quality. The company licenses its technology to makers of televisions, computer screens, and consumer electronics devices. It has strategic relationships with such technology leaders as Sony Corporation (NYSE: SNE). Eastman Kodak (NYSE: EK) is a major competitor.

The stock has been a steady gainer over the past month, in response to such issues as word from Sony and Toshiba that they will begin commercial production of OLED televisions. Analysts remarked favorably on Universal Display's prospects in the matter. The company has been working with Sony to develop OLED sets since 2001, and customer LG. Philips LCD (NYSE: LPL) sells panels to Toshiba. Shares are advancing through a positive trading channel. The price is currently consolidating at the base of that channel, suggesting the potential for a turn back toward the top.

Brokers recommend the issue with three "strong buys," two "buys" and two "holds." Analysts see a 44 percent growth rate through the next year. The PANL Price to Tangible Book ratio (7.61) compares favorably with industry, sector and S&P 500 averages. Institutions hold about 48 percent of the outstanding shares. Over the past 52 weeks, the stock has traded between $11.00 and $19.66. A stop-loss of $15.75 looks good here. Note that the company is next expected to report quarterly results in early November.
