No surprise as to the worst performing share of the year. Expansive accounting software firm Xero has dropped back from giddy heights and a good deal of US hype which saw its market capitalisation peak at above $5 billion earlier this year.
Naturally the roller coaster ride has prompted plenty of reaction from analysts and media. But to its credit - and that of the CEO Rod Drury - the company has never been too interested in the share price.
Even as it was rising fast Drury maintained a steely focus on the company's long term growth strategy. On that basis his relative lack of interest in the falls this year is easy to understand.
The second biggest faller on this list (taken from the NZX50 index), Pacific Edge Biotechnology is suffering from a similar slump following the mini-tech boom late last year.
