A disappointing week for health supplements company Blackmores, which saw its share price sink by almost 23 per cent, has divided investors and analysts on whether the stock presents an attractive entry position, or will continue to slide.

The vitamin-maker has fallen out of favour over the last three years, down 60 per cent since hitting its record high of January 2016 on the back of unprecedented demand from Chinese consumers. The stock closed on Friday at $94.50.
