Now what

Applied Optoelectronics' rise has only continued in early March, including a 7% jump today on nothing more than a bullish analyst report on head-to-head rival Oclaro (NASDAQ: OCLR).

All told, AOI investors have enjoyed a 125% return year to date and a triple in six months. The fiber-optic networking sector as a whole is bouncing back from a couple of slow years, ready to pounce on the next wave of telecommunications infrastructure upgrades. In particular, cellular network operators are preparing to roll out another generation of high-speed networking standards, requiring a lot of additional fiber-optic capacity to be added on the back-end of those hyper-connected cell towers.

The orders are already pouring in. Applied Optoelectronics may be looking back at a massive share price surge, but the stock still trades at a fairly cheap 14 times forward earnings.

This rally could keep going for a while.
