In afternoon trade the S&P/ASX 200 (Index: ^AXJO) (ASX: XJO) has followed the lead of U.S. markets and is down almost 0.2% to 5,927 points.
Four shares that have fallen more than most today are listed below. Here's why they have tumbled lower:
The Appen Ltd (ASX: APX) share price is down almost 5% to $9.64 despite there being no news out of the tech company. But considering its shares were up 295% over the last 12 months prior to today, I suspect that profit-taking is weighing on its shares. While it might be worth waiting to see if it falls further, I think this share price weakness could be a buying opportunity for investors willing to make a patient buy and hold investment.
The G8 Education Ltd (ASX: GEM) share price has tumbled 4% to $2.71 despite the release of a favourable broker note yesterday and a flurry of insider buying. On Wednesday Morgans initiated coverage on the childcare operator with an add rating and $3.53 price target. The broker believes G8 Education is positioned to return to organic growth after recent changes in the industry.
The Retail Food Group Limited (ASX: RFG) share price has fallen 3% to $1.06. Investors have continued to head to the exits after the embattled food and beverage company's disastrous half-year update and its decision to suspend its dividend indefinitely. I think there could be more declines ahead for Retail Food Group's shares, so would caution investors against buying the dip.
The St Barbara Ltd (ASX: SBM) share price has dropped to 3% to $4.05 despite the gold miner advising that its Simberi operation in Papua New Guinea has resumed production following the resolution of an illegal work stoppage initiated by a contingent of its workforce. Management still expects to achieve its full-year production guidance of between 115,000 and 125,000 ounces of gold despite the interruption.
