Fake fighters YPB Group (ASX:YPB) was leading the pack this morning putting on 44 per cent to reach 2.6c. The shares cooled to 2.4c by 1pm AEST.

The brand protection outfit earlier this month announced it was ramping up its focus on Australia and New Zealand companies exporting to China.

Consumer access and anti-counterfeit tech was essential to Asian export success — particularly using QR codes, the company said.

Cancer tester Bard1 Life Sciences (ASX:BD1) gained 33 per cent to 2c in early Friday trade before slipping back to 1.8c at 1pm AEST.

Global investment bank Credit Suisse joined the stock’s register last week — initially taking a 5 per cent stake.

Earlier this year, independent testing confirmed high accuracy for detection of ovarian cancer with 89 per cent sensitivity (the number of patients correctly identified as having cancer) and 82 per cent specificity (the number of people correctly identified as not having cancer).

That followed previously announced study results from January — confirming the test’s robustness and potential utility as a diagnostic aide for early detection of ovarian cancer.

Luxury retailer AHAlife (ASX:AHL) bounced back from yesterday’s decline to trade up 21 per cent at 2.3c.

The stock had no news in the market.

Respiri (ASX:RSH) today released the first functional prototype of its second-generation wheeze monitor — pushing shares from 12c as high as 15.5c. The stock was trading at 13.5c at 1pm AEST.

Respiri’s latest version provides the capabilities of a digital stethoscope for asthma patients and carers to measure wheezing.

Now it’s on to commercialising the device. Respiri says it has a clear path to commercial launch early next year.

Junior tin miner Aus Tin Mining (ASX:ANW) surged 30 per cent to 2.2c in morning trade before it was halted at 1.9c at 11.30am.

The explorer — which is expanding its Granville Tin Project in Tasmania — asked for a trading halt pending the release of an announcement next week.

In the red

Embattled NSW coal producer NuCoal (ASX:NCR) fell as much as 40 per cent in early trade after it told shareholders they wouldn’t get any compensation from an ongoing legal battle with the NSW government.

Shares fell to 1.1c in early trade before recovering to 1.3c at 1pm AEST Friday.

It has been four years since the New South Wales government cancelled a NuCoal Resources coal exploration licence — and the company is still seeking retribution.

Estrella Resources (ASX:ESR) continued its slump — down 21 per cent to 2.2c — almost half its open price on Monday.

Estrella released results yesterday, saying it had intersected cobalt, nickel and copper mineralisation in its latest drilling — including 11 metres at 0.12 per cent cobalt and 0.38 per cent Nickel from 36 metres.

Now, it’s going back to survey the area again with high-power technology.

The shares recovered to 2.5c by 1.10pm AEST Friday.

Junior copper and lithium play Traka Resources (ASX:TKL) dropped 20 per cent to trade at 4c after releasing news of its Mt Cattlin North joint venture with Galaxy Resources. The shares were at 4.2c at 1.10pm AEST.

Drilling of 42 holes found 2 metres at 0.84 per cent lithium oxide, and another 3 metres at 0.62 per cent.

Galaxy said it had more success with its rock-chip sampling and it would focus on a “whole of project” assessment rather than one target at a time.

Conclusion of MEC Resources’ (ASX:MMR) latest seismic survey has seen its stock drop 14 per cent to 1.8c.

MEC told the market today it had concluded a survey off the Newcastle coast and processing would commence shortly.

Cow tracker Sensera (ASX:SE1) fell 13 per cent to 22c despite showing off its tech to investors in Dubai overnight.

Its quarterly released earlier this week showed record revenue of $2.85 million for the period and $1.65 million in cash receipts.

For the full financial year, it set its revenue guidance at between $8.4 million and $9.3 million.
