2021 was overall a more stable year than 2020 for ASX investors, but some companies still experienced hefty gains – some across the whole year but others on just a single trading day.

In 2021 there were 17 ASX companies that rose by 200% or more on an intraday basis. In 2020, that number was 40; in 2019, just 10 companies hit the mark.

Compared to last year there were fewer instances of companies rising without any news but far more companies rising as a result of major transactions – including welcoming new substantial shareholders and spin-offs.

Here’s a list of all ASX companies that rose by 200% or more intraday in 2021…

The one ASX company that rose by over 1000% in one day

Only one ASX company rose by over 1,000% on an intraday basis and it was iron ore play Mindax Limited (ASX:MDX).

Its gain came on its first trading day for nearly two years having raised $2 million in fresh capital and obtained Foreign Investment Review Board (FIRB) approval for Norton Gold Fields’ proposed earn-in for its Mt Forrest Project.

Another company to rocket upon re-entry to the ASX was uranium play Aura Energy (ASX:AEE).

This company, which has a project in Mauritania, timed its run perfectly being boosted by a recently completed DFS as well as a hot run in the uranium spot price.

Two other companies to make the list were spin-offs.

One was Kuniko (ASX:KNI) which holds the Norwegian base metals projects of Vulcan Energy (ASX:VUL).

The other was Evolution Energy Minerals (ASX:EV1) which contains the Chilalo Project in Tanzania once held by Marvel Gold (ASX:MVL).

After investing in two ASX tech companies last year, 2021 was quieter for Bevan Slattery but in February he chipped $2 million into Rent.com.au (ASX:RNT) which led to the stock more than doubling on the day he bought in and surpassing 30 cents within a fortnight.


Mineral Discoveries

This year there were three ASX companies with intraday gains above 200% as a consequence of mineral discoveries.

The first was Lefroy Exploration (ASX:LEX) which recorded an outstanding intercept at its Burns gold-copper prospect back in February.

Next was Coda Minerals (ASX:COD) which in June hit 200m of “intense IOCG alteration”, including ~50m of copper sulphides at the ‘Elizabeth Creek’ project in South Australia.

Rounding out the list was Metal Hawk (ASX:MHK) which in September netted massive nickel sulphide mineralisation from RC drilling at its Commodore prospect near Kalgoorlie in WA.


Mystery intraday gainers

Just three companies this year rose more than 200% in a day on no news. Two of those instances came in back to back days from the same company.

One was Aquis Entertainment (ASX:AQS) which owns Canberra’s casino.

On a Thursday in late February it rose from 3.7 cents to 11.5 cents and the following morning rose as high as 75 cents – both off the back of no news.

The other was microcap Amani Gold (ASX:ANL) which on October 1 rose from 0.1 cents to 0.35 cents.

Similar to Aquis, Amani’s response to the consequential speeding ticket was ‘nothing to see here, officer’.
