Could this be the explanation?

Circle Health have been on a public relations offensive in the last few weeks, and this culminated in the appearance on the 1st August of their Chief Executive, Ali Parsa, on both Radio 4's Today programme, but also on BBC2's Newsnight.

On both programmes Parsa gave the same message, much of it plain wrong. He said that Hinchingbrooke will "have balanced books this year" when the first quarter's results showed that they made a £2.3m loss which was £652k more than they had planned. He then said that Germany spends the same as the UK on healthcare, and this is largely on private providers like his company, yet Parsa claimed that the German providers had greater patient satisfaction than the NHS. His claim was unsubstantiated and does not fit in with the facts: Germany spends much more (12% of a much larger GDP than our 10% of GDP) than the UK on healthcare and Germany report access to healthcare issues almost as worse as the US (and five times worse than the UK) and the Commonwealth Fund ranked Germany two places below the UK in patient satisfaction. Parsa topped-off his tirade with the Conservative accusation that GPs are private providers (which they are not for many reasons). The BBC (in the form of Justin Webb of Today and Kirsty Wark of Newsnight), left the worst claims of Parsa to go unchallenged, through ignorance rather than bias.

So why isn't Ali Parsa taking a long August vacation, why is he in the media at a time when most people are watching the Olympics? The reason may well be the following graph: the share price of Circle Holdings over the last 12 months (screen shot from Interactive Investor):

Over the last year the share price of Circle Holdings has fallen from around 200p a year ago (at the time of a large share offering and the listing of CIRC on the AIM stock market) to a value of about 80p now (it even fell as low as 44p for a few days).

This is not the graph of a company with a bright future: investors are showing their lack of confidence in the company. Mix into this the results from 2011 where Circle Holdings made a loss of £13.6m (EBITDA) and the announcement from the government that they will no longer pay Independent Sector Treatment Centres (ISTCs, like Circle's treatment centre in Nottingham, the only part of their business to make a profit) above the NHS rate (and hence this is a cut in payment of about 20%), and you have a company that should be panicking.

On the first of August Parsa was in firefighting mode. His media appearances were to reassure investors, to try and get the share price out of the slump it has been in for two months. The following graph shows the effect of Parsa's efforts:

He added 5p to the price (82.5p) before it fell back to 80p: the share price is still in a slump.

Parsa clearly has a lot more work to do to get the share price back up to its high of 200p, so expect a lot more media appearances in the next few months.

UPDATE:
In a piece on Open Democracy Richard Whittell of Corporate Watch says:

"Earlier this week [31 May] Circle Health went to investors to raise money, partly to help pay off £14 million it had borrowed from hedge fund James Caird Asset Management, at a staggering interest rate of 25 per cent."

Could this be the reason for the sharp drop in Circle share price at the beginning of June?

UPDATE2:
Further searches came up with the following from Reuters confirming Whittell's statement:
