Riverbed Technology -- great company but too extended?

Glancing through the Over-Valued Over-Bought Report at the Alert HQ Premium site I noticed that Riverbed Technology (RVBD) was on the list.

The following chart gives you an idea about the over-bought aspect:

In terms of over-valued, consider some of the measures by which we generally evaluate stocks at Trade-Radar:

• PE is 242, roughly 8 to 10 times higher than most growth stocks
• Price to Sales is 7.33 close to triple what we see in many tech stocks with good growth characteristics
• PEG is 1.75, high even for a growth stock
• Enterprise Value to EBITDA is over 67 which is 10 times what you might see in a value stock and at least 6 times what you might see in other good growth stocks

Granted, the company is executing extremely well. Riverbed just reported Q3 earnings of $0.34 versus $0.27 estimates. Revenue increased 17% sequentially to $148M vs $135M estimates. Nevertheless, it's hard to see how that justifies the valuation measures described above.

After today's drop of 3.35% perhaps investors are coming to the same conclusion.
