(ShareCast News) - Oakley Capital Investments Limited (OCL) founder and chief executive Peter Dubens has splashed the cash and sent shares in the AIM-listed investment company surging higher. Dubens, who floated OCL in 2007, bought £1.6m-worth of shares, buying 950,000 at a price of 137p and a further 200,000 at 145p.These are his only shares in OCL, which was founded in order to provide AIM investors with access to the investment strategy being pursued by Oakley Capital £750m private equity investing strategy.Annual results from OCL showed net asset value up 7.5% to 215p per share in the six months to end-June, an increase of 18.1% over the year.The 15p uplift in NAV per share is attributable to the strong performance of the private equity funds and favourable exchange rate movements following Brexit, though the uplift was tempered by a fall in NAV per share of 7p from the post-IPO share price of Time Out as it listed in June.Since then, OCL enjoyed a 9.4p lift to its NAV from selling a controlling stake in Parship Elite dating service to Germany's ProSiebenSat media group that represented a 3.6-times money multiple on Oakley's original investment and an internal rate of return of roughly 150% in just 16 months.At the time of results in September, Dubens said: "Whilst Brexit created volatility, both positive and negative, at the period end, the underlying portfolio performance showed continued strength. That was further reinforced by a very attractive return from the Parship Elite Group investment just after the period end. We retain a highly valuable stake in the ongoing success of this business.
