A popular Wendy's commercial in the 80s made famous the question: "Where's the beef?" Good one. And here's an even better one: "Where's the alpha?" You might want to whip this one out the next time you meet with your portfolio manager.
Alpha is the over-and-above-the-expected return. It is the "value added." Therefore, it makes sense that a positive alpha means an investment has outperformed its market-predicted return, while a negative alpha would mean just the opposite. The expected return is calculated by a formula that takes into account the investment's level of unavoidable risk (aka beta).
Ever stepped into an elevator and after the doors close you become aware of an almost-suffocating scent coming from the woman next to you who must have bathed in perfume? Well, as you know, once the doors close you can't escape the smell until the ride is over. This is similar to beta, which is risk that can't be reduced or diversified away. A measure of "systematic" or market related risk, beta is used as a measure relative to a certain index -- such as the S&P 500.
So, for example, let¿s say your portfolio is managed to compete against the S&P 500. If you generate a better return than the index while not taking on added risk (standard deviation of returns) then you get alpha. Low beta means the market-related risk is low and vice versa for high beta.
Another example, let's say a mutual fund or stock has a beta of 1.5 relative to the S&
P500 ¿ that means it is 1.5 times as risky. So, over time, if the S&P 500 goes up 1%, your portfolio should be up 1.5%
plus (one can hope) some percentage of alpha. If the S&P 500 is down 1%, your portfolio should be down 1.5%.
Alpha
and beta are based off of linear regression of a set of data. Warning: this may cause a high school fifth-period flashback,
but it will be over before you know it:
The equation for a line is Y = a + bX.
a = alpha (the Y intercept - the added
value)
b = Beta (the coefficient you multiply X by)
X = S&P 500 (in this case)
Y = your portfolio

Greater China's LED Lighting Manufacturers Predict Export Boom Due to Broader Range of General Lighting Applications -- China Sourcing Report
Comtex
HONG KONG, May 5, 2008 /Xinhua-PRNewswire-FirstCall via COMTEX News Network/ ----Eighty-one percent of Greater China LED light fixture suppliers predict strong export growth of 10 percent or more in the next 12 months, due primarily to a wider range of LED-based general lighting applications. This is according to Global Sources' (Nasdaq: GSOL) China Sourcing Report: LED Light Fixtures (http://www.ChinaSourcingReports.com/ledlightfixtures ) .

''The use of LEDs in functional everyday lighting is moving into the mainstream, especially in developed markets. This, in turn, is fueling product development, with Greater China manufacturers seeking to gain an edge through improved performance and application flexibility,'' said the Report's publisher Spenser Au.
Among surveyed LED lighting suppliers' product development plans for the coming months:
-- 59 percent are focused on general lighting applications; -- 22 percent are improving optical / lighting design; -- 11 percent are developing models with brighter output; and -- 8 percent are working to decrease decay / deterioration rates.
Most Greater China Suppliers Predicting Strong Growth, Targeting EU Market
''Greater China suppliers are predicting strong export sales of LED fixtures, as demand grows and they expand their product lines to include a wider range of lighting applications,'' said Au.
Among surveyed Greater China manufacturers: -- 67 percent said export sales are expected to increase by 20 percent or more; -- 14 percent expect increases of 10 to 20 percent; and -- 19 percent expect sales to stay flat or to grow by less than 10 percent.
Suppliers are focused on exports to Western markets where the relatively high cost of LED lights versus standard lights is not as much of an issue. Among surveyed suppliers, 56 percent are targeting the EU and 35 percent are targeting exports to the United States.
Au said: ''As applications for LED lighting expand and the cost of diodes and other key components drops, most suppliers see the market as poised for growth.''
