The S&P/ASX 200 (Index: ^AXJO) (ASX: XJO) is marginally up in afternoon trade with several stocks inside and outside the index soaring higher.
When it comes to investing the best businesses tend to keep on winning, so it's worth noting what might be behind the share price gains of some of today's big market movers.
Reffind Limited (ASX: RFN) is a small-cap technology company up 11% today and 573% in 2015 as the company continues to win major clients for its employee administration technology platforms. Reffind is not dissimilar to US-based online work administration and communication juggernaut Slack and looks a business for the top of the watch list.
Sirtex Medical Limited (ASX: SRX) is up 3% to $34.07 despite the business releasing no specific news to the market. The global healthcare business is a beneficiary of a lower Australian dollar and with a range of analysts having valuations above the market price the cancer treatment business may continue to see support into 2016.
Oil Search Limited (ASX: OSH) has climbed 2.3% to $7.62 as the LNG producer continues to attract investor interest thanks to its strong balance sheet and high-quality LNG producing assets located in PNG. The business recently rejected a one-for-four scrip takeover offer from Woodside Petroleum Limited (ASX: WPL) and has leverage to any rebound in energy prices currently around multi-year lows.
Senex Energy Ltd (ASX: SXY) is another beaten-down energy producer up around 5% to 21.5 cents today, but still down a whopping 57% over the past year. Senex has extensive prospects in the energy rich Cooper-Eromonga and Surat Basins, although tumbling energy prices have taken their toll on margins. Those betting on Senex at today's knocked-down prices stand to benefit if energy prices rebound higher in 2016.
Servcorp Limited (ASX: SRV) is a family run global office leasing business with some impressive growth credentials. Today the stock is up 3.2% to $6.85 and is up around 85% over the past two years. Since the GFC the business has posted five consecutive years of strong revenue and profit growth and looks a stock for the top of the watch list.
