The S&P/ASX 200 (Index: ^AXJO) (ASX: XJO) is on track for another weekly gain after rising 1% during today's session. However, a number of companies are generating even greater gains for investors, including these four:
Senetas Corporation Limited (ASX: SEN) has endured a tough couple of months on the market, but it has rebounded 16.7% today to trade at 17.5 cents. Although there is no company-specific news to explain the lift, it's possible that investors are simply taking advantage of the company's beaten-down price. Senetas provides high-speed data encryption hardware designed to protect data travelling between sites.
Fortescue Metals Group Limited's (ASX: FMG) short sellers (those who have bet on its share price falling) might be developing a nervous twitch now – the shares are up another 4.6%, giving them a total gain of 44% since late last month. Today's gains can likely be attributed to yesterday's quarterly production report, which showed further cost reductions during the period.
NIB Holdings Limited (ASX: NHF) surged 7.9% with its shares now trading at $3.42. The rally comes after the private health insurance business agreed to buy the medical insurance book of OnePath Life for $22.6 million, boosting its exposure to the New Zealand market. Although it is still subject to regulatory approval, the acquisition would give it a customer base of more than 200,000 New Zealanders.
Liquefied Natural Gas Ltd (ASX: LNG) rose as much as 13.4% earlier in the session, but has since given up most of those gains to trade 5.2% higher at $1.61 per share. Although oil prices fell overnight, they have regained ground today with Brent crude oil fetching a little more than US$50 a barrel. As liquefied natural gas prices are linked to oil prices, LNG Ltd relies on higher oil prices to make its projects economically viable.
