A number of ASX growth shares have fallen sharply over the past year.

I think some of those falls have created good opportunities for investors willing to take a longer-term view.

These are two I would be happy to buy today, with recent broker price targets suggesting potential upside of around 18% to 77%.

ResMed Inc (ASX: RMD)

ResMed shares are trading around $30.55 today, down almost 28% on a 12-month basis.

I continue to like the long-term opportunity in sleep apnoea and respiratory care.

The company sells devices, masks, and software to help diagnose and treat sleep-related breathing conditions. Despite ResMed’s size today, diagnosis and treatment rates remain relatively low globally, which leaves the business with plenty of room to keep growing.

ResMed has also recently agreed to sell its MatrixCare software business for US$400 million in cash.

Ord Minnett believes the sale makes sense because MatrixCare was complementary to the wider business rather than central to ResMed’s focus on sleep apnoea and respiratory care.

The proceeds are expected to be returned to shareholders through an accelerated share buyback.

The broker has trimmed its earnings forecasts slightly following the sale, although the lower number of shares following the buyback should provide some offset.

Ord Minnett has a buy recommendation and a $36.20 price target. From today’s share price, that points to potential upside of around 18%.

I think that would be a strong return from a business that still has a large global market ahead of it.

WiseTech Global Ltd (ASX: WTC)

WiseTech shares are currently trading around $35.24 after a very difficult period for investors.

Despite that weakness, I still like the long-term position of its CargoWise logistics software.

CargoWise is used by major freight forwarders and logistics companies around the world. Once software becomes deeply embedded in the day-to-day running of these businesses, switching to another platform can be expensive and disruptive.

WiseTech’s FY26 result was broadly in line with Morgans’ expectations, although CargoWise revenue growth of 11% was softer than the broker had hoped.

One positive was the progress WiseTech made on costs. The company delivered approximately US$115 million of annualised run-rate savings during FY26, which should help margins as the business moves through FY27.

Management expects revenue growth to be weighted towards the second half of the year as new initiatives begin contributing. Its underlying EBITDA guidance also points to margins returning towards 49% to 51%.

Morgans remains positive, retaining its buy rating and setting a $62.50 price target. From today’s price, that suggests potential upside of approximately 77%.

Foolish takeaway

I would buy both of these ASX growth shares at current prices.

ResMed still has a long runway in sleep apnoea and respiratory care, while WiseTech could offer much greater upside if the business delivers on its plans and investor confidence starts to recover.

Neither investment is without risk, but I think the potential long-term rewards make both worth a closer look.

Rio Tinto Ltd (ASX: RIO) shares are climbing higher again in Wednesday lunchtime trade.

At the time of writing, the shares are up around 2% for the day, and are trading at $179.98 each.

Today’s increase means the ASX mining stock is now up 21% higher for the year-to-date, and they’re 53% higher than 12 months ago.

For context, the S&P/ASX 200 Index (ASX: XJO) is down slightly, by around 0.2% at the time of writing, and around 1% higher than a year ago. 

What is causing the Rio Tinto share price rally?

Copper prices are reaching fresh record highs this week as supply struggles to keep up with rising demand from data centers, renewable energy projects and power grids.

According to Trading Economics data, copper futures have climbed to around US$6.8 per pound, up significantly from around US$4.5 per pound around 12 months ago.

Major copper-producing countries in South America have also faced operational challenges this year, contributing to weaker output and exports. And at the same time fears about potential US tariffs has encouraged traders to ship directly to US warehouses, tightening supply elsewhere in the market.

And the increase is good news for Rio Tinto. The company has diversified away from its heavy reliance on iron ore, becoming a major player in the copper market.

The shift has boosted the company’s earnings too. For the first half of FY26, Rio Tinto reported a 28% increase in its underlying EBITDA. 

And underlying EBITDA for the company’s copper business surged 84% to US$5.7 billion, making up roughly 36% to 39% of total group earnings. Copper, aluminium and lithium now contribute more than half of the miner’s underlying EBITDA.

Rio Tinto’s underlying fundamentals are clearly very strong. But now the question is, can the shares keep climbing higher, or have they reached fair value?

Are the mining shares a buy, sell or hold now?

After an impressive rally over the past 12 months, it looks like Rio Tinto shares could be trading around fair value.

TradingView data shows that the experts are divided about their outlook for the shares. Out of 15 analysts, six have a buy/strong buy rating and another six have a hold rating on the shares. Another three have a strong sell rating.

But after the latest rally, the average $171.92 target price now implies a potential 4% downside, at the time of writing. Although some still tip an upside of up to 10%, to $198.01 over the next 12 months. 

The team at Morgans has a hold rating on the mining shares. The broker notes that iron ore remains the primary earnings driver for Rio Tinto, leaving profits exposed to movements in commodity prices and Chinese demand. It added that, given this balance of quality and cyclical risk, the shares now look to be trading at fair value.

Santos Ltd (ASX: STO) shares are trending higher in Wednesday morning trade.

At the time of writing, the shares are up around 2% and are changing hands at a six-year high of $8.54 each.

The latest increase means the oil and gas company’s shares have increased around 39% for the year-to-date, and they’re also up 12% compared to this time last year.

What is driving the shares higher this year?

The ASX energy shares shot higher in 2026 off the back of ongoing conflict between the US and Iran. Volatility in the region has fuelled significant concerns about tighter global oil supply and rising prices.

The shares spiked in February and March, around the time news first broke that conflict had escalated between the two nations. The shares continued climbing in value as the war heated up.

Santos shares cooled in June off the back of news that the two nations could soon reach a peace agreement, but strikes have resumed in the region this week, reigniting inflation fears and pushing the energy company’s shares to a fresh high.

The shares have also been supported by the company’s strong half-year FY26 results announcement, which it posted last month.

Santos reported a 2% year-on-year increase in sales revenue and a 1.7% increase in production volumes. The company also generated free cash flow from operations, driven by strong base business performance.

The business could continue strengthening this year

It looks like the oil and gas business is well placed to keep increasing its production in the coming reporting periods, which could help boost its earnings even further.

Just this week, Santos announced that it has agreed to spend around US$189 million ($262 million) to buy another 3.3% of the Papua LNG project from TotalEnergies SE (NYSE: TTE).

The deal is still subject to regulatory approvals and a final investment decision. This is currently targeted for the fourth quarter of 2026.

If it goes ahead, Santos expects its share of LNG production from Papua LNG to rise by around 19% to about 1.2 million tonnes per year.

So, what do brokers tip for Santos shares next?

It looks like the experts are bullish about the outlook for Santos shares over the next 12 months.

Market Index data shows that all brokers have a strong buy rating on the stock. But after the latest rally, the $8.57 average target price now implies around a 0.5% upside, at the time of writing.

Sentiment is also very positive on TradingView. Out of 15 analysts, 13 have a buy/strong buy rating on Santos shares. Meanwhile, one analyst rates it a hold, and one rates the energy share a sell. 

The average $8.75 target price implies a potential 2% upside ahead, at the time of writing. But some expect the shares to jump around 24% to $10.60 within the next 12 months.

Citi reaffirmed its buy rating on the ASX 200 energy share following its half-year update. The broker also raised its target price to $9, which is a little above the average.

Elsewhere, Morgans has a hold rating on Santos shares. The broker noted that the results beat estimates, but that it is impossible to quantify the risks posed by the Federal Government’s gas reservation policy ahead of its release.
