But updating a raft of profitable holdings is easy. Researching and formulating reasoned advice on shareholdings that are underwater is a completely different matter even if, on reflection, you decide that the investment case remains sound. So, with this in mind, I am revisiting one of my real-estate holdings from my 2011 Bargain Share portfolio; First Property (FPO), a company that has yet to enjoy the re-rating it rightly deserves, but one that, in my view, offers investors a decent entry point at the current price of 18p. This is modestly below the level I originally recommended buying at 21 months ago. It's timely, too, because the Aim-traded commercial property fund manager is due to announce results for the six months to 30 September 2012 on Wednesday 5 December.
