M&A activity again helped the Finextra50 Financial Technology Index close higher last week, as it ended Friday up 0.7% to 82.36. Polaris Software and GL Trade led the gainers after the Indian software company outlined acquisition plans following on from strong results and the French dealing systems vendor announced an acquisition offer from SunGard. Meanwhile, poor quarterly results for Online Resources and Total Systems Services saw them lead the index's few fallers.
