AIM's leading shares opened brightly but the AIM 100 index is slowly drifting back towards last night's closing level.
The AIM 100 index was up 1.3 points at 3,311 at around 9.30am, having risen as high as 3,318 at one point.
Xeros Technology Group PLC (LON:XSG) was the AIM 100's top riser, up 14.2% at 226.18p on the back of well-received interims.
The developer of patented polymer bead systems used in a revolutionary laundry system boasted of progress on all fronts. Earned income increased to £744,000 in the five months to the end of 2015 from £95,000 the year before. The group is in the process of changing its financial year-end date, hence the five-month reporting period.
"The roll out of Commercial Laundry continues at a good pace. We are now installing machines at an approximate rate of one per working day and expect this rate to progressively increase,” said Mark Nichols, chief executive officer of Xeros.
Loss before tax widened to £5.61mln from £3.84mln, but this is not uncommon in early-stage technology companies.
The AIM All-Share advanced 0.1% to 707, with Gulfsands Petroleum PLC (LON:GPX), Fitbug Holdings PLC (LON:FITB) and SolGold PLC (LON:SOLG) leading the way.
Gulfsands saw its market cap increase by more than a third, following on from yesterday's stonking rise, as a delayed reaction to Friday's results kicks in.
Wearable technology firm Fitbug rose 16% to 0.73p after it announced the success of an initial roll-out of its Digital Wellness Solution with the company's strategic partner Punter Southall Health & Protection.
SolGold, meanwhile, climbed 16% to 4.36p, meaning it has practically doubled in price since the start of the year, as the price of gold recovers.
e-Therapeutics PLC (LON:ETX) revealed it is targeting partners to accelerate the development of its drug discovery engine.
The update came as the firm unveiled results for the full year to end January, a period in which it said the platform continued to exceed expectations by generating high quality compounds.
Investors chased the shares 9.1% higher at 13.5p.
The FTSE Small Cap was down five points at 4,522, with its mixed performance reflected in the fortunes of Primary Health Properties PLC (LON:PHP), down 6.4%, and Johnston Press PLC (LON:JPR), up 16%.
Primary Health saw its shares slide to 103.375p at it proposed to raise up to £120mln by issuing shares at 100p, while Johnston advanced to 47.5p after its full-year results contained no nasty surprises, with underlying earnings (EBITDA) of £57.3mln in line with expectations.
In the wider market, the FTSE 100 was down 35 points at 6,150 and the FTSE 250 was off 77 points at 16,785.
