SiRF's Warning Spells Trouble for All of Tech

This morning, SiRF Technology (SIRF - commentary - Cramer's Take) delivered another substantial revenue warning. Tech stocks had begun to rally, thanks to recent positive developments at Tiffany (TIF - commentary - Cramer's Take) and Bear Stearns (TIF - commentary - Cramer's Take).

But SiRF's warning could quash any incipient tech rally -- at least in the consumer electronics components space.

We had a glimpse of a possible brewing storm back in early February when companies serving the handset space issued cautious guidance. I'm speaking specifically of ARM Holdings (ARMHY - commentary - Cramer's Take), SiRF, National Semiconductor (NSM - commentary - Cramer's Take) and Infineon (IFX - commentary - Cramer's Take).

It didn't help that Texas Instruments (TXN - commentary - Cramer's Take) lowered its revenue forecast in mid-February for the ongoing quarter by about $120 million, a figure that could translate to 5 million to 7 million mid- to high-end 3G phones. A week later, Sony Ericsson warned of a 4 million handset shortfall, citing high-end weakness.

Putting these last two warnings in context has been a challenge. Are they an isolated incident that can be pegged to market share losses for Sony Ericsson in the current quarter? That would seem unlikely considering that Sony Ericsson's new product launches from October and November were so well received and clearly gave the company decent volume momentum from the third quarter to the fourth in 2007.

Both TXN and SE warnings were big -- they caught the industry by surprise even after the recent Nasdaq tumble.

That's why this morning's SiRF warning is intriguing. SiRF sells GPS chips to both vedors of personal navigation devices such as Garmin (GRMN - commentary - Cramer's Take) and handset companies like Samsung.

PNDs, which typically use GPS chips, were one of the hottest consumer electronics segments in 2007; global unit sales soared by triple digits to nearly 40 million. The other big winner of 2007 was the smartphone -- 50% volume growth to 120 million units during the year.

The PND and the smartphone form an interesting pair. Both still often sell above the $300 price point, definitely fitting the high-end consumer electronics niche. The market grew to such a high level globally that high price points can become a challenge. So both seem to be uniquely vulnerable to consumer angst of any real substance.
