In afternoon trade the S&P/ASX 200 (Index: ^AXJO) (ASX: XJO) is on course to have a solid finish to the week and is up 0.3% to 5,995 points.
Four shares unable to follow the market higher are listed below. Here's why they are ending the week in the red:
The APA Group (ASX: APA) share price has tumbled almost 5% to $8.93 after Goldman Sachs downgraded it to a sell rating. The broker has made the move on the back of slowing growth and regulatory risk. Goldman has placed a 12-month target price of $8.30 on APA Group's shares.
The Japara Healthcare Ltd (ASX: JHC) share price is down 2% to $2.15 after Dow Jones announced that it would be removed from the S&P/ASX 200 at the next quarterly rebalance. Fellow aged care operator Regis Healthcare Ltd (ASX: REG) and financial services company FlexiGroup Limited (ASX: FXL) were also ejected from the index.
The Nufarm Limited (ASX: NUF) share price is down 3% to $8.45 following the release of yesterday's disappointing trading update. Management expects first half earnings before interest and tax to be between $70 million and $80 million, which is lower than the prior corresponding period's EBIT of $85 million.
The St Barbara Ltd (ASX: SBM) share price has fallen almost 4% to $3.26. Considering the gold miner's shares hit a 52-week high this week, today's decline is likely to be a case of profit taking. Investors appear to have been pleased with St Barbara's investment in promising upstart Catalyst Metals Ltd (ASX: CYL).
