The S&P/ASX 200 (Index: ^AXJO) (ASX: XJO) is having a positive finish to the week. In early afternoon trade the benchmark index is up 0.3% to 5,961 points.
Four shares which haven't been able to follow the market higher today are listed below. Here's why they are ending the week in the red:
The Adacel Technologies Limited (ASX: ADA) share price has plunged almost 18% to $2.54. Although the flight simulator company confirmed at its AGM that it expects profit growth of 35% year-on-year in FY 2018, it warned that the majority of this growth would come in the second-half. Management also advised that the FAA intends to award components of a new field support contract to a small engineering and support services company instead of Adacel.
The Costa Group Holdings Ltd (ASX: CGC) share price has tumbled 3% to $6.58 following the release of a broker note out of UBS. The broker has downgraded the horticulture company's shares to a neutral rating with a $6.80 price target following yesterday's annual general meeting.
The Nearmap Ltd (ASX: NEA) share price has fallen 4% to 66 cents a day after its annual general meeting. Although the online photomap content provider reported strong momentum in the U.S. market, it doesn't appear to have been enough for some investors.
The Slater & Gordon Limited (ASX: SGH) share price is down 8% to 4.5 cents after providing an update on its shareholder claims. According to the release, its former auditor Pitcher Partners is now seeking to make a third party claim against Slater & Gordon. The original statement of claim filed against Pitcher Partners alleged that the auditor had wrongly signed off on statements that inflated Slater and Gordon's revenue.
