It's impressive when some businesses just keep performing year after year. I'm going to highlight three unstoppable ASX shares worth buying and owning for the long-term.
Compounding is a very powerful financial force, which can drive our net worth higher over the long-term.
When investments are seeing rapid growth of earnings and underlying value, this could mean great returns for our portfolio.
Let's run through three exciting prospects for a $3,000 potential investment.

Temple & Webster Group Ltd (ASX: TPW)
This e-commerce business sells furniture and homewares and it's benefiting from the adoption of online shopping.
The company highlighted in its FY25 result presentation that the Australian furniture and homewares market had reached 20% online penetration, while the UK market is at 29% and the US market has reached 35%. Those two markets indicate that further online adoption is possible in the coming years.
The unstoppable ASX share is growing at a rapid pace, showing it's delivering on its potential. In FY25, Temple & Webster's revenue rose by 20.7% to $600.7 million. In FY26 to 11 August 2025, revenue growth accelerated to 28% year-over-year.
In the next few years, it's aiming to reach $1 billion of annual sales through growth of its core offering as well as its home improvement segment.
The company aims to reach an operating profit (EBITDA) margin of at least 15% in the long-term suggesting significant improvement of the bottom line and operating leverage.
WCM Quality Global Growth Fund (ASX: WCMQ)
In my view, the investment team at WCM have proven they're very effective at choosing global stocks that have improving competitive advantages. The other factor WCM looks for are businesses that have a corporate culture which fosters the improvement of those advantages.
It's the economic moat (competitive advantages) of a business that sets it apart from competitors, so a strengthening competitive position should help it deliver improving profits for shareholders.
Some of the current businesses in the portfolio include AppLovin, Taiwan Semiconductor, Saab, 3i Group and Rolls Royce Holdings.
The investment team have performed very well for this exchange-traded fund (ETF), with the WCM fund delivering a return of an average of 16% over the last five years. Past performance is not a guarantee of future performance, but the returns have been impressive.
As a bonus, it aims to deliver a minimum annualised cash yield of 5% per year.
Pinnacle Investment Management Group Ltd (ASX: PNI)
Pinnacle is one of the most impressive businesses in the financial services space – it's invested in a number of leading fund management businesses such as Plato, Hyperion, Resolution Capital, Solaris, Metrics, Pacific Asset Management, Life Cycle and Firetrail.
Its earnings are growing rapidly. The company's compound annual growth rate (CAGR) of earnings per share (EPS) has been 28.3% over the five-year period to June 2025. I'd describe that as an unstoppable ASX share.
At 30 September 2025, the total affiliate funds under management (FUM) had increased 10% over the quarter to $197.4 billion with net inflows of $13.3 billion over the three months.
With impressive outperformance of their benchmarks over a 5-year, Pinnacle's affiliates are clearly doing well and I think this bodes well for future inflows and FUM growth.
It recently announced it plans to acquire up to 13% of Advantage Partners over a three-year period, the largest independent, diversified private markets platform in Japan. The initial 5% stake is for A$92 million, with an option for a further 8% at a similar valuation.
Further affiliate investments and organic FUM growth is a promising prospect.
