Veeco Instruments (VECO) soared to a new 52-week high of $54.50 this morning, as traders cheered the company's latest earnings report. In fact, the shares are now lingering in territory last explored nearly nine years ago. So, is it too late for bulls to jump on the stock's bandwagon?

Well, not necessarily. VECO is currently hovering above several potential levels of technical support, including its 10-day and 20-day moving averages. Plus, the stock's Relative Strength Index (RSI) of 73 is planted in overbought territory, suggesting the equity could be due for a pullback. As evidence that buying pressure is beginning to wane, VECO has retreated steadily since tapping that new 52-week high earlier in the session.

"New York-based Veeco (VECO) is one of three major providers worldwide of specialized equipment to the LED and solar industries, along with other instruments for measuring on a nano-scale level, in the pharmaceutical, data storage and materials science fields," notes Brendan Coffey.

The editor of The Cabot Green Investor explains, "The company has been involved in thin-film deposition for 30 years and has amassed a portfolio of 300 intellectual patents that help maintain at least something of a wall against competitors."
