Bernstein Research analyst Toni Sacconaghi today cut his rating on EMC to Market Perform from Outperform. He retains his $19.50 price target.

Sacconaghi offered three primary reasons for the downgrade.

  • He thinks the stock is fairly valued at current levels. Sacconaghi says the stock looks cheap on a sum-of-the-parts basis, given the company’s large stake in VMware (VMW), but cautions that “it is not a slam dunk that the company will successfully monetize its ownership stake.” If VMW were spun off, he writes, “the large increase in its float could pressure the stock,” given that the valuation is supported partly by a scarcity premium that would be eliminated.
  • Sacconaghi also is wary on IT spending, and notes that the company has lower recurring revenue then some other companies he covers, while also having relatively high exposure to the financial sector.
  • And finally, he is concerned that the VMware valuation is too high, “in the face of rising competitive intensity and potential price pressure in the second half.” Sacconaghi sees potential headwinds for VMW, including the the second-half shipment of Microsoft’s (MSFT) Hyper V virtualization software, intensifying price competition from both Microsoft and Citrix (CTXS) and the lack of a significant new product cycle in FY 2008.

EMC today is down 43 cents, or 2.4%, to $17.54. VMW is down $1.81, or 2.6%, to $67.49
