The retailer is planning to beef up its marketing campaigns to help try and entice shoppers ahead of Christmas.
However it has no idea if this will help reduce the amount of excess stock.
Dick Smith in October slashed up to S$8 million off its full year net profit guidance, saying it would fall to between $45 million and $48 million.
CMC Markets chief market analyst Ric Spooner said the update from the electronics retailer contrasted with more upbeat reports from other discretionary retailers recently, including David Jones, Myer and Oroton.
"It is obviously concerning, I think, for shareholders, coming as it does against a background of some signs that the overall consumer discretionary retail sector is doing a bit better, though they are only modest signs," he said.
"It does appear, at least prima facie, to be related to Dick Smith's competitive position and the attractiveness of their offers."
In October, Dick Smith said sales growth had been well below the level achieved between July and September, despite more advertising.
The sales slide dented the group's expectations for the key Christmas trading period.
A year ago, the retailer outlined plans for 450 stores across Australia and New Zealand as it reported a 10 per cent leap in sales for the first 15 weeks of fiscal 2015.
