The S&P/ASX 200 (Index: ^AXJO) (ASX: XJO) is on course to finish the week on a positive note. In early afternoon trade the index is up 0.4% to 5,621.5 points.
Four shares that have failed to follow the market higher today are listed below. Here's why they are ending the week in the red:
The Audio Pixels Holdings Ltd (ASX: AKP) share price is down a further 4.5% to $21.00. The digital speaker developer's shares have come under pressure again possibly from profit taking after going on a tear this month. Its shares rose strongly after announcing the achievement of three major technological breakthroughs that management believes demonstrate the progress the company has made towards delivering its "breakthrough technology" to the market at long last.
The BWP Trust (ASX: BWP) share price has dropped 3% to $3.58. This decline is almost entirely attributable to the Bunnings landlord's units going ex-dividend this morning. Eligible BWP unit holders can now look forward to receiving its 8.9 cents per share interim distribution in their nominated accounts on February 22.
The DEXUS Property Group (ASX: DXS) share price has fallen 2.5% to $10.77. As with BWP Trust, the selling today can be attributed to DEXUS Property Group's units trading ex-dividend this morning. Eligible unit holders will be paid this 27.4 cents per unit distribution on February 28.
The Starpharma Holdings Limited (ASX: SPL) share price is down a further 6% to 92.5 cents. The healthcare company's shares have fallen heavily this week after the U.S. FDA advised that it wants confirmatory clinical data before it will approve its promising VivaGel product. The company's CEO appeared to be very disappointed with the decision, but pledged to work with the FDA to understand how it can come to provide the necessary clinical data for approval.
