They said much of Dick Smith's problem was likely to lie in private label accessories, which would be difficult to clear.
"We fear the group will be forced to discount branded hardware in an effort to attract shoppers to its stores, which could force JB Hi-Fi to follow suit," the analysts said.
But Chris Wilkinson, of consultancy First Retail Group, questioned how much "wiggle room" New Zealand electronics retailers had to ramp up discounting in response to Dick Smith's efforts.
"The sector has intensely low margins," he said.
Dick Smith's sales slump has left the firm - which had already slashed profit guidance in October - facing a A$60 million writedown.
Managing director Nick Abboud said yesterday that the writedown and uncertain outlook for trading meant Dick Smith was unable to stand by its previous profit forecasts.
"We remain cautious on the outlook for the Christmas trading period," he said.
Dick Smith shares closed down 57.6 per cent yesterday, at A28c, but have bounced back today, recently trading at A33.5c.
Wilkinson said Dick Smith had suffered from having a "clouded" brand proposition in the minds of consumers.
"It's tried to move heavily into own-branded product, unlike their competitors such as JB Hi-Fi who've leveraged very strongly the manufacturers like the Samsungs of this world," he said.
"Dick Smith's in no man's land and I think they are incredibly vulnerable."
