The S&P/ASX 200 (Index: ^AXJO) (ASX: XJO) has had a slow start to the week and finds itself down 0.1% to 5,949 points in afternoon trade.
Four shares which have fallen more than most today are listed below. Here's why they have started the week in the red:
The a2 Milk Company Ltd (Australia) (ASX: A2M) share price has fallen 2% to $7.04 on the eve of its annual general meeting. With so much growth already built into its share price, investors appear to be nervous about its forthcoming trading update and full-year guidance.
The Baby Bunting Group Ltd (ASX: BBN) share price has tumbled almost 9% to $1.37 following a disappointing trading update at its annual general meeting. According to the release, management has revised its EBITDA guidance due to the negative impact clearance activities have had on the business. EBITDA is now expected to be flat in FY 2018.
The JB Hi-Fi Limited (ASX: JBH) share price has fallen 3% to $21.91 after it emerged that Amazon is set to launch its AmazonBasics range in Australia. According to Business Insider, these products are on its website now but not on public display. Not only are these products likely to go head-to-head with many of JB Hi-Fi's offerings, but they are expected to be cheaper.
The Wattle Health Australia Ltd (ASX: WHA) share price is down 5% to $2.18 in what appears to be a classic case of buy the rumour and sell the fact. This morning Wattle health confirmed that it has received confirmation from China that is CFDA application has been accepted and is currently undergoing final review. This will allow Wattle Health to sell infant formula in China next year when regulations change.
