Online grocer Ocado today celebrates its first year as a listed company. But after 365 days in which one of its biggest shareholders sold out of the company and its share price, although currently above its listing price, continued to trail its index, it may still be too early to call one of the biggest IPO stories of 2010 a success.

The company, launched by three ex-Goldman Sachs bankers, listed on the London Stock Exchange a year ago today at a price of 180p a share - it quickly fell to close at 167p. This morning it was trading at 190p, marking a 5.5% increase on its initial listing.
