But not all All Ords shares are having such a down day today. So let's take a look at three All Ords shares that are making their investors very happy.

3 ASX All Ords shares bucking the market on Monday

Audinate Group Ltd (ASX: AD8)

Audio visual technology share Audinate is our first All Ords stock worth a look today. Audinate shares are tearing it up this Monday. The company is currently enjoying a massive 11.85% rise at present, putting the Audinate share price at $8.02 a share:

This comes after Audinate reported its half-year results for the first half of FY2023 this morning. As we covered this morning, the company reported an impressive 39.3% rise in revenues to US$20.6 million, while gross profits were up 30% to US$14.5 million. Clearly, investors have been delighted by what the company had to say.

HT&E Ltd (ASX: HT1)

Next up, we have All Ords media and advertising share HT&E. Here, There and Everywhere, the company formerly known as APN News and Media, has had no fresh news or earnings out today. But that didn't stop the company's shares from rocketing 10% to $1.32 apiece at one stage this morning. They've now settled 3.75% higher at $1.245 a share:

This could have something to do with speculation that HT&E could be the target of a takeover offer. According to reporting in The Australian, the company's financials have spurred some potential suitors, including some private capital firms, to weigh up their options.

Helios Energy Ltd (ASX: HE8)

Finally today, we have the All Ords oil and gas hopeful Helios Energy. Helios shares are another ASX winner this Monday, with the company up a lucrative 8.59%, to 10.75 cents per share:

Helios hasn't put anything new out today. However, ASX energy shares are collectively surging today, thanks to rising oil prices. As my Fool colleague flagged this morning, WTI crude rose 2.2% last Friday, while Brent crude was up 2.4% to US$86.52 a barrel.

Thanks to these gains in the oil markets, oil shares ranging from All Ordinaries small-cap players like Helios to giants like Woodside Energy Group Ltd (ASX: WDS) are putting on very pleasing performances.

With that financial year done and dusted, we take a look at the 5 best energy shares on the All Ords to have held from 1 July 2020 through to 30 June 2021.

Spurred on by higher energy prices, these shares all returned 3 or more times the gains posted by the All Ords.

Paladin Energy Ltd (ASX: PDN)

With an FY21 share price gain of 376%, Paladin Energy is hands down the best performing ASX energy share over this time.

The uranium producer has projects in Australia and Africa. It has, among other factors, benefited from rising uranium prices and speculation of still higher prices to come as the world re-examines nuclear power as a means to cut global carbon emissions.

Paladin closed the financial year trading at 51 cents per share.

With 2.68 billion shares outstanding, Paladin currently has a market cap of $1.34 billion.

Karoon Energy Ltd (ASX: KAR)

The second best performing ASX energy share is Karoon Energy. Karoon shareholders enjoyed a 124% price gain during FY21.

The oil and gas exploration company is engaged in projects in Australia, Brazil, and Peru.

Like other energy companies, Karoon has enjoyed some healthy tailwinds from rising crude oil prices. At the beginning of the 2021 financial year, a barrel of brent crude oil was selling for US$42 (AU$56) per barrel. Today that same barrel is worth US$75, an increase of 79%.

Karoon closed the year at $1.34 per share. With roughly 554 million shares outstanding, Karoon has a market cap of $737 million.

Senex Energy Ltd (ASX: SXY)

Coming in at number 3 is Senex Energy, with a financial year share price gain of 87%.

The oil and gas explorer and producer has projects in South Australia and Queensland. And it, too, will have benefited from rising crude and LNG prices, among other drivers.

Senex closed FY21 at $3.43 per share. With just under 184 million shares outstanding, it has a market cap of $630 million.

Senex also pays a dividend yield of 1.16%, 96% franked.

Helios Energy Ltd (ASX: HE8)

With a share price gain of 77%, Helios is the fourth best performing ASX energy share in FY21.

The oil and gas explorer is focused on its Trinity and Presidio projects in the US state of Texas. Trinity is comprised of 3,128 acres of oil and gas leases.

Helios closed the financial year at 18 cents per share. With some 1.65 billion shares outstanding, the company has a market cap of $289 million.

Energy Resources of Australia Limited (ASX: ERA)

Rounding out our list of top 5 ASX energy shares is Energy Resources Australia. The share price gained 74% in FY21.

The company operates the Ranger Uranium Mine in the Northern Territory, and processes and sells uranium oxide.

Like Paladin, Energy Resources Australia has been a beneficiary of higher uranium prices, as nations around the world (chiefly China) are upping their nuclear power ambitions.

Energy Resources Australia closed the year at 26 cents per share. With approximately 3.7 billion shares outstanding, it has a market cap of $960 million.

Like many ASX shares, particularly energy related shares, Helios' share price was more than cut in half during the COVID-19 induced bear market. The share price fell 53% from 21 February through to 18 March.

It wasn't until July that the Helios share price truly began to recover, closing at 15 cents per share on Wednesday, up 88% from 18 March. That gives Helios a market capitalisation of $232 million.

Year to date, Helios' share price is down 21%.

What does Helios Energy do?

Helios Energy is an oil and gas company with both of its major projects in Texas in the United States. Its predominant focus is the Presidio Oil Project located in Presidio County. To date, Helios has drilled two vertical wells into the Presidio Oil Project.

Its other project, the Trinity Oil Project, is located along the borders of Trinity, Houston and Walker. Trinity is comprised of 3,128 acres of oil and gas leases.

Why is Helios Energy's share price running higher in August?

With both of its oil projects in Texas, one of the states that's been hit hardest by the raging pandemic, you might expect Helios' share price to fall, not gain 15.4% to date in August.

I see three apparent reasons for Helios' share price leap.

First, the price of oil has trended higher this month. West Texas Intermediate (WTI) crude oil has gained 4.4% in August, currently trading for US$42.07 (AU$59.25) per barrel.

Second, investors are likely betting on higher crude oil prices to come when the world emerges from the coronavirus driven slowdowns. This should see a large increase in the demand for petrol and other products derived from oil.

Third is Helios' quarterly report which was released to the ASX on 3 August. While noting the company's compliance with Texas COVID-19 ordinances, Helios also stated its 2D seismic results had increased its Ojinaga Shale Formation play area by 50% to approximately 300,000 acres.

The Helios share price gained 7.7% on 4 August, following the release of its quarterly report.
