Updated: The rumour is SVS Securities is shutting for business. Is this the end for broker to esteemed enterprises such as Westminster Group (WSG) and Mosman Oil & Gas (MSMN) and another sign of how tough things are developing for brokers at the lower end of AIM? Certainly, calling the company has not seen anyone pick up the phone to us…er yes: all staff were asked to leave the building at 11 AM. Expect a forman announcement on Monday. So much for the FCA keeping investors informed…
