Of 11 brokers covering WLF, 9 are on BUY and 2 are Hold. Not a single broker recommends a Sell. This is fairly unusual for a tech stock.
After revised forecasts for 2007, the PER is now 14.10 and - importantly - profit growth for 2007 is forecast at 22%
I believe WLF could better this but a growth rate of 20% would make them look rather cheap.
