Shares in Autonomy are the worst performers today after a poor reception to its second quarter figures. Revenues in the three months to 30 June rose to $195.2m from $125.7m a year earlier, while adjusted profit before tax, which excludes various charges, climbed to $89.6m from $50.8m. Broker UBS remains a fan. "Sales of $195.2m and an EPS of $0.27 ($0.26 diluted) were in-line," it said. Concerns in the market centre on the performance of Interwoven, the content management company Autonomy acquired in January, but UBS downplays these. It remains bullish on the stock and has left its 12 month price target unchanged at 1,475p. "While the only comment on the outlook was of cautious optimism and for normal Q3 seasonality, we continue to see a chance FY09 earnings guidance will be raised," UBS added. Oil and gas installation specialist Petrofac is the best performer. It has been awarded a 48-month gas development contract in Abu Dhabi. It is the first project to be awarded to Petrofac Emirates. The contract is worth around $1bn to Pacific Emirates.FTSE 100 - RisersPetrofac Ltd (PFC) 729.00p +5.04%Fresnillo (FRES) 583.50p +4.01%Home Retail Group (HOME) 289.50p +3.39%Land Securities Group (LAND) 476.50p +2.97%Schroders (SDR) 858.00p +2.88%SABMiller (SAB) 1,328.00p +2.87%3i Group (III) 241.50p +2.66%BT Group (BT.A) 108.00p +2.47%FTSE 100 - FallersAutonomy Corporation (AU.) 1,192.00p -9.56%Eurasian Natural Resources (ENRC) 725.00p -2.55%Anglo American (AAL) 1,758.00p -2.33%Legal & General Group (LGEN) 56.14p -2.08%Diageo (DGE) 879.00p -2.06%Sage Group (SGE) 178.20p -1.71%Tullow Oil (TLW) 921.50p -1.39%TUI Travel (TT.) 232.00p -1.17%
