LinkedIn (LNKD, $97) currently trades at 11.1x the 2012 consensus revenue estimate. For Facebook (FB, $28.80) to trade at similar valuation, the stock would need to fall to around $20.17.

Facebook (FB, $29.35) shares have dipped below the $30 level, hitting a post-IPO low of $29.23. The stock is now off 22.7% from its IPO price of $38.

With the market cap down to $80.1 billion, Facebook trades at 16.1 times the 2012 consensus revenue estimate of $4.96 billion. On the 2013 consensus estimate of $6.45 billion, the price-to-sales (P/S) ratio is 12.4.

How low can Facebook shares go? A pullback to 10x estimated forward revenue would mean the stock slumps to around $18.25. That seems unlikely. But this stock is proving anything is possible.

At 13x forward revenue, Facebook shares would be around $23.70. At a forward P/S ratio of 15x, there’s downside risk to $27.30.

RBC Capital says the recent pullback in Apple (AAPL, $567.50) shares creates an attractive entry point. The firm expects Apple to benefit from multiple positive catalysts over the coming months. RBC has a $700 price target on Apple.

Needham cuts its NetApp (NTAP, $28.06 pre market) price target to $38 from $49 to reflect the company weak guidance for the July quarter. The firm remains confident in NetApp’s positioning in the storage segment, but says macro headwinds are a near-term concern.

On the earnings call last night, NetApp management said the EMEA region was experiencing longer sales cycles and smaller deal sizes, while demand from the financial services vertical in the U.S. deteriorated over the past 90 days.

As part of the restructuring, the company expects to cut its workforce by 8%, eliminating about 27,000 jobs.

NetApp (NTAP, $24.90 after hours shares are getting killed in after-hours trading, off more than 24%. The problem is weak fiscal Q1 (July) guidance.

After the close, the storage vendor reported fiscal Q4 (April) EPS of 66 cents, three cents above the consensus estimate, on revenue of $1.7 billion, vs. the consensus of $1.68 billion.

For fiscal Q1, NetApp sees EPS of 34 cents to 39 cents, well below the consensus of 59 cents, on revenue of $1.4 billion to $1.5 billion (down 4% to up 3% year over year), below the consensus of $1.61 billion.

Facebook (FB, $35.01) shares are off more than 8% just after the open. Traders had all weekend to think about the company’s valuation and many decided they didn’t like it after all.

It was a fight to the finish for the Facebook (FB, $38.23) underwriters to keep the stock above its IPO price of $38. After opening at $42.05 and quickly trading up to a high of $45, Facebook shares started heading lower, twice testing the $38 level, first in the morning and then during the final half hour. After all the hype, it would have been quite embarrassing if Facebook turned into a Busted IPO (trading below its initial offer price) in its first session. Of course, there’s always Monday.

Facebook (FB, $40.05) opened for trading at $42.05, just 10.6% above the IPO price of $38. The current market cap is $109.8 billion.

Juniper Networks (JNPR, $17.96) shares are off more than 5% today following last night’s cautious comments regarding the tech-spending environment made by John Chambers on the Cisco Systems (CSCO, $17.09) earnings call. The stock took out the December low of $18.05.

Chambers had one positive thing to say on last night’s Cisco Systems (CSCO, $17.19) fiscal Q3 earnings call:

The acceleration of the datacenter and specifically the UCS business, years ahead of our competition, is just one example where we grew Q3 revenue over 50% -- 57% year-over-year for the UCS business, while each of our top 2 data center competitors had flat or negative growth in their service business in the most recent quarter.

Our results from the datacenter over the last year are an example of our history of seeing market trends early and having the ability to react quickly, both technologically as well as operationally. We have done what we said we would do and position the company for long-term growth and shareholder value, and we continue to do the work internally to position the company going forward.

The Facebook IPO roadshow is expected to kick off on May 7 and the stock could begin trading as early as May 18, according to Reuters.

Some traders are looking at Zynga (ZNGA, $8.71) as a play into the Facebook IPO. Zynga shares have come down from the March 2 high of $15.91 in part on concerns about the recent OMGPOP acquisition.

Broadcom (BRCM, $36.71) reports Q1 EPS of 65 cents, 10 cents above the consensus estimate, on revenue of $1.83 billion (including $33 million from the NetLogic acquisition), vs. the consensus of $1.78 billion.

Revenue from the company’s broadband communications unit fell 3% sequentially (better than normal seasonality), while revenue from the mobile/wireless unit was flat sequentially. Infrastructure & networking revenue was down 3% sequentially excluding NetLogic.

In the wireless segment, revenue from 3G basebands exceeded 2G baseband revenue one quarter ahead of expectations; management is “feeling significantly better about the 3G business” and expects sequential growth in Q2.

On the networking side, management looks for improved carrier spending into the end of the year. This business unit should see a sequential revenue improvement for the June quarter.

For Q2, Broadcom guided revenue to a range of $1.9 billion to $2 billion, vs. the consensus of $1.97 billion.
