"The rise in shares versus the drop in gold over the past year is very interesting. It signals that investors are actively seeking better-performing – but riskier – assets," said head of investment policy at Lloyds Bank Private Banking, Ashish Misra.
Misra said the boost in confidence in U.K. assets, which picked up in the second half of last year when speculation over when and how much the Fed would scale back stimulus peaked, showed that private investors were becoming more sophisticated.
"The spikes in sentiment in the wake of policy decisions such as the Federal Reserve postponing QE tapering of its asset purchase program in September 2013, goes to show how the average private investor is becoming more sophisticated and knowledgeable. With this in mind, it will be interesting to see how the current crisis in Ukraine will affect investors' sentiment towards Eurozone shares," Misra said

U.K. commercial developers said that private new build activity rose at the sharpest pace in February in the 11-year history of the Commercial Development Activity survey, released on Wednesday.
"The positive outlook for the market is clearly feeding through to development activity levels considering February's survey high – with future expectations remaining robust we expect to see further improvements in activity levels over the coming months," said Simon Collett, head of building & project consultancy at Savills.
