The optical frenzy started with Tellabs ( TLAB) continuing its string of reports that beat expectations and continuing to offer good guidance. JDSU ( JDSU) followed with an impressive quarter, and then when Finisar ( FNSR) blew the doors off the joint, the optical frenzy kicked into overdrive. Now you've got the mo-mo folk piling into any name they can find that has the word "optical" in it. I'd been taught for years on Wall Street that it's a big bearish indicator when speculative names like these start rocking. But at some point, Rev Shark flipped that logic on me and taught me that speculation is actually very bullish for those who are nimble enough to embrace it and move on from it quickly when the froth dies down. To be sure, I have owned core positions in many optical names for a long time, and I continue to hold core positions in each of the aforementioned names, because it's looking increasingly as though the fundamentals in the optical world have finally turned. I did trim some of those names this morning, but I'm planning to hold positions in these names regardless of whether the speculation dies down tomorrow.
