GOOG Google estimate cut details (364.45 ) -Update- As mentioned at 6:55, Goldman Sachs cut their Google tgt to $490 from $500 and cut their '06 & '07 ests. Firm's new estimated 29% y/y growth (vs. 39% prev) for '06 affiliate net rev vs. 73% in '05 reflects their view that future growth will not be aided by new affiliate partners that boosted GOOG's '05 growth. Firm says the uncertainty in 2006 for Google is that network revenue may not benefit from new affiliate deals and could rely solely on the query and RPS growth of existing affiliates. In addition, they note the possibility that Google could actually experience a net loss of affiliates in 2006.
