Shares in YouGov (LON:YOU) jumped nearly 5 percent in early morning trading on Monday, after reporting a 78 percent profit boost over the first half of its financial year.

Pre-tax profit hit £4.5 million over the six month period, up from £2.5 million a year earlier. Revenue at the data analytics company more than doubled to £56.3 million.

The group pointed to a “significant US weighting” in their revenues, which allowed them to remain positive about performance despite Brexit uncertainty.

“Trading during the second half has continued positively,” the company said.

“While ‘Brexit’ continues to create uncertainty in the economic and political environment, especially for UK and European businesses, the international spread of our revenues–with a significant US weighting–positions our business well to cope with, or even gain from, potential volatility.

“In the context of both the macro-environment and our own plans to accelerate our investment in technology and geographic expansion, we remain confident of our expectations for the full year.”

Shares in YouGov jumped 4.11 percent to 390.00 (0835GMT).
