NEW YORK ( TheStreet) -- Accenture ( ACN) shares got a boost late Thursday after the New York-based consulting giant topped Wall Street's expectations for its quarterly results, lifted its outlook for fiscal 2011 and amped up ts dividend.

The stock was up 3.4% to $43.93 on volume of roughly 420,000 after the closing bell, according to Nasdaq.com. Based on the regular session's close at $42.49, the shares were up almost 2% year-to-date, and the afterhours lift puts them in shouting distance of a 52-week high of $44.67 on April 26. The stock was sitting below $37 at the start of September, but rallied along with the broad market.

For the three months ended August 31, Accenture earned $504 million, or 66 cents a share, on revenue of $5.42 billion, beating the average estimate of analysts polled by Thomson Reuters for a profit of 63 cents a share on revenue of $5.31 billion in the period.

The company said it now expects earnings of $3 to $3.08 per share in fiscal 2011, a forecast for growth of 13%-16%. Its prior view was for growth of 12%-15%. Wall Street's current consensus calls for a profit of $2.92 a share in the year ending next August. Accenture took its semi-annual cash dividend up 20% to 45 cents a share.

A big loser in extended trades was DynaVox ( DVOX), which was down almost 19% to $6.59 on volume of around 170,000.

The move came after the Pittsburgh-based education software maker warned Wall Street that its fiscal first-quarter results would be weak and withdrew its outlook for the whole of fiscal 2011, citing soft demand "for both its speech generating devices and software products."
