Impax Asset Management (LON:IPX) is widely followed on the Small Cap Valued Report, especially by Graham Neary. The share price has risen sharply recently and I have come to the conclusion it is now significantly over valued.
I calculate market cap as a percentage of assets under management (Graham's preferred measure I think) to be 3.1%. I don't think it has ever been this high before and the closest I can see it has ever been was back in early 2014 with 2.8% on a share price in the mid-50s. Following this the share price was under 50p in Autumn 2016 with a ratio of 1.4%. I accept that scale means a higher ratio is justified, but I don't think to this extent and they have also been much cheaper on this basis recently.
Furthermore TNAV is much weaker than a year ago even before the payment of a special dividend and I think this will constrain future distributions and growth by acquisition. And even if they could fund further takeovers without significant dilution I don't think there is another PAX and so the positive effect from this must be considered a one-off.
Finally, although inflows remain impressive in their non-PAX funds, both these and investment returns have faltered somewhat recently especially when including PAX. There remains (IMHO) a risk of a 40%+ correction in US stocks which would badly affect both.
Consequently I have now sold almost all of my holding. I think they are well run in an attractive sector and am hoping to buy back much more cheaply in 1-3 years time.
I tend to agree with you. But I have some of these shares in a buy and hold strategy for my children - so I am not thinking of selling imminently. Two comments though. One I am not sure how relevant the P/AUM metric is. There is so much drop through to the bottom line in the asset management business through increasing assets (at least if the manager is not diversying into new strategies). However, even on a P/E basis, I think that room for growth of AUM is not unlimited for Impax (apart from a couple of the lower margin PAX products). At some point Impax is going to hit capacity constraints in its most lucrative products.
