In reviewing the CREE chart, the stock price has been in a downtrend since March. Like many stocks, showed a big sell off in March, with some recovery by mid-June, and a punctuated decline since ... what gives?

uhhhh...a bear market?

More than just a bear market ... but a consistent decline in stock price (hey, I'm long on CREE) .... here's the correct link for trend line for CREE:

www.bigcharts.com/intchart/frames/main.asp?symb=cree&time=&freq=&country=us

Here's a few other stocks for comparison:

ITWO (strong uptrend)

RIMM (Big crash, consolidation, trend to recovery)

Well maybe we should listen to the market and concede that we are all wrong and that this stock sucks?

What the hell is a blue laser anyways?

CREE is at 91 after hours ... nice ... based on the chart expect it to go to 125 or so ... bought a bunch near the bottom as a trade ... but the chart still sux ... connect the peaks since June recovery and the trend is down ... not "sophisticated" technical analysis, just eyeballing ... can't explain it, the metrics look great ... JDSU has an ugly chart, too, but check out ITWO or JNPR or CHKP or AC ... nice steady up trends ...

Blue laser ... think of a laser as a mallet that hits the 1 and 0s of digital info ... red laser is a big mallet ... blue laser is small mallet ... cause red light has longer wavelength than blue ... so can pack in more info ... more 1 and 0s ... on a CD or DVD when using a blue laser ... CREE's potential innovation is a semiconductor based laser ...

A blue laser allows reading/writing to a CD/DVD in a much more compact format. Thus allowing approximately 4 or 5 times more information to be contained on either a CD or DVD.

The applications go further than just DVDs, there is higher quality laser printers and scanners (like the ones at the grocery store) for two more examples. I remember reading that there were a few more possibilities with the blue laser but can't remember that at the moment.

Newb,
Current infrared lasers emit light waves at 980 nanometers,blue lasers emit light at a wavelength of 490 nanometers.
What does that mean?Blue lasers work at 1/2 the wavelength or twice the frequency ,resulting in 4 times as many beams of light on a given medium.
The result is that CD,s,DVD,s,copiers,scanners,printers,medical equipment using blue lasers would have 4 times the accuracy of the present method.
End result:A discontinous innovation in the above mentioned applications.

AzMax,long on Cree.

Hi Tinker,

those interested in details of the blue/violet GaN LEDs and lasers, can find details in a slide show here:

http://www.eurotechnology.com/bluelaser/

There are also slides which explain the use of GaN lasers for DVD storage, and why they pack information more densely than previous red lasers.

There you'll also find the details of a book about blue LEDs and lasers by one of the key inventors.

Best regards,

Yes, actually unless there are special tricks (which also exist), the storage density goes with the inverse square of the wavelength of the light. You can find this explained graphically in the following slide:

Yes, the storage density normally (unless tricks are used) goes with the inverse square of the wavelength). You can find that explained here:
