A quick look at the share price history of PCI-PAL PLC (LON:PCIP) - the stock has doubled in the past few months - would suggest that the secure payments provider was primed for a placing.
And that's exactly what happened on Tuesday. PCI-PAL raised ?4.95mln from investors by issuing shares at 45p apiece - a 29.5% discount to the average mid-market closing price for the last 30 trading days.
The cash injection will be used to grow the firm's North American operations and will also fund increased marketing expenditure across the pond.
Given the placing discount, it was unsurprising to see the stock fall back 23% to 55p late on Tuesday.
Modern Water PLC (LON:MWG) flowed to the top of the leaderboard in London after the water treatment specialist announced it had made significant progress with its wastewater treatment project in Gibraltar.
The government of Gibraltar has awarded an advanced works contract to the joint venture - Modern and Northumbrian Water - which covers the design and survey work required for final planning and environmental approvals, as well as preliminary site works.
These are the final steps before work can begin on the overall project, which will be capable of treating urban wastewater and storm flows for the entire country.
As part of the JV, Modern Water is responsible for the designing and building part of the contract, with Northumbrian Water responsible for the plant's operation and maintenance for 20 years.
Boss Simon Humphrey said he was "delighted" with the progress and it seems investors were too, with shares almost doubling to 82.2%.
The Quarto Group Inc (LON:QRT) was another on the up after the illustrated book publisher put in a strong trading performance in the second half of 2017.
The group expects to report revenue and profits in line with the guidance given in its November trading update, when it issued a profit warning.
Net debt at the end of the year was US$64mln, up US$2.1mln from a year earlier but down from US$75.8mln at the halfway point of the year.
"While 2017 was, overall, a challenging, transitional year, we are now a pure-play intellectual property business. We are particularly pleased with our strong trading performance in the second half, including the holiday period, with our Children's business once again showing growth," said chief executive Marcus Leaver.
Shares are up 9.1% to 162p as the markets move into the afternoon session.
Filtronic PLC (LON:FTC) was one of the biggest casualties in London after the antenna maker scaled back its full-year forecasts.
The AIM-quoted firm had expected a number of pilot and development contracts to lead to production orders later in the year.
But progress on this front has been slower than expected which means the second half performance will be "broadly similar" to that of the first half.
Speaking of the first half, Filtronic also revealed on Tuesday that interim revenues slumped to ?12.8mln (H1 2017: ?21.6mln) in the six months ended November 30 as large orders which dominated prior years were completed, while operating profits halved to ?1.8mln.
Shares plunged almost 20% to 9.25p.
Ferrum Crescent Ltd (LON:FCR) shares jumped today after the firm posted a maiden JORC resource at its Toral zinc-lead project in Spain.
The resource rings in at 16mln tonnes of ore grading 6.9% zinc equivalent, including lead credits, and 25 grams per tonne silver.
In terms of metal in the ground, that amounts to 670,000 tonnes of zinc, 540,000 tonnes of lead and 13 million ounces of silver.
And there could be more, as the deposit remains open along strike to the east and down dip.
"Our immediate objective now is to build on this maiden JORC resource estimate and increase its size and thereafter carry out a preliminary economic assessment," said executive director Laurence Read.
"Having said that, I have no doubt that our project is well positioned against its peer group with the clear potential to become a future mining operation."
The stock jumped 8.8% to 0.11p on Tuesday Morning.
