A placement in the top ten daily trades list has caused the number of long term investments in two companies to increase.

According to Barclays Wealth, the firms Petro Matad and Blinkx have demonstrated that clients are reacting to good news on businesses reported in the media.

Mongolian oil company Petro Matad saw shares leap from 59p to 89p on July 13th after it was announced that the firm had stuck oil in one of its drilling projects in the country.

In addition, the video search engine Blinkx also saw a healthy rise in its share prices after Samsung announced that it was to start using the software in its mobile phone applications.

Paul Inkster, head of product at Barclays Stockbrokers, added that overall BP continues to dominate the market, with 16 per cent of all trades carried out by Barclays brokers being made in favour of the firm.

It is a continuation of the increased confidence in the company seen last week, when share prices rose by 12p following positive news regarding the oil cap.
