Among the best performing stocks last week (week 42) on the Australian sharemarket were a mixture of energy and mining companies: Nexus Energy (NXS), Paladin (PDN), Pan Australian Resources (PNA), AWB, Mt Gibson Iron (MGX), Sino Gold (SGX), Roc Oil (ROC) and Flight Centre (FLT). All the above best performing stocks for week 42 stocks managed more than 10 percent gain on the trading week. Nexus Energy was the overall winning stock taking in a 16 percent increase after new company takeover speculation and the recent increase in the oil price. Paladin took the ribbon for the best performing stock on the ASX 100 index seeing an 11.5 percent rise or 78 cents and closing at $7.55. On the ASX 200 index, Pan Australian Resources took pole position increasing by 13 percent, adding 11 cents and closing at 95 cents. Other runners up on the ASX 200 index were AWB adding 12.7 percent (close $2.76, +0.31), Mt Gibson Iron adding 30 cents (close $2.75, +12.24%), Sino Gold increasing by 82 cents (close $8.11, +11.24%), Roc Oil adding 35 cents (close $3.62, +10.7%) and Flight Centre adding $2.30 or 10.4% and closing the trading week at $24.40. The Australian closed Friday business lower at US89.01 cents, Gold was at US$768.90, All Ordinaries closed at 6723.3 and ASX 200 at 6706.3. It is interesting to note that Paladin was a loser a few weeks ago and also in March this year. Mt Gibson Iron was a previous winner. AWB was a previous winner in January. Another recent best performing stock was singo Gold (SGX) from last month. Read a previous recommendation for Roc Oil.
