Small caps have taken a breather after five straight days of gains.

The Small Ordinaries index of 100 small-cap companies dipped 0.1 per cent to 3,027.6 on Wednesday, while the ASX200 gained 0.6 per cent to 6,683.3 – just one point away from recouping all of its losses for 2020.

The Emerging Companies index of microcap companies dipped 0.8 per cent to 1,843.9.

Revasum (ASX:RVS) was the biggest gainer on Wednesday, soaring 155 per cent to 31c after shipping its flagship 6EZ silicon carbide wafer polisher to a major global semiconductor wafer manufacturer in the United States for six months of testing.

Revasum says the 6EZ polisher would make the industry more efficient as it moves to larger wafer sizes.

Elsewhere in the small cap space:


Linius (ASX:LNU) rose 6.3 per cent to 3.4c after the Melbourne cloud-based video conferencing company launched a new product that allows users to immediately search, assemble and share video content from within recorded meetings.

Cann Group (ASX:CAN) rose 8.9 per cent to 55c after the cannabis company announced that the Office of Drug Control had granted licenses for cultivation and production of medical cannabis at its new Mildura facility. Cann Group received a $50 million bank loan this week to move forward with the cannabis project.

Rhinomed (ASX:RNO) was flat at 18c after successfully registering its nasal swab with the Australian Therapeutic Goods Administration as a class one medical device. The swab could be used for self-administered tests for coronavirus and other upper respiratory tract disease and is more comfortable than current tests, the company says

Spectur (ASX:SP3) dipped 1.3 per cent to 7.8c after the solar-powered surveillance company launched a New Zealand subsidiary, Spectur NZ, with its Kiwi reseller Deus Ex.
