After a strong run for the share market, it's not unusual for investors to start wondering whether a downturn could be around the corner. Bear markets are a normal part of the investing cycle, but that doesn't make them any less uncomfortable when they arrive.
The good news is that not all companies are affected in the same way during tougher market conditions. Businesses with stable demand, reliable cash flow, and strong market positions can often provide a bit more resilience when sentiment turns negative.
With that in mind, here are three ASX shares that I think could offer investors some peace of mind if markets become more volatile in 2026.

Woolworths Group Ltd (ASX: WOW)
Woolworths is one of the most defensive businesses on the Australian share market.
As the country's largest supermarket operator, it sells everyday essentials that households continue to buy regardless of what the economy is doing. Food, household goods, and basic necessities tend to be far less sensitive to economic cycles than many other industries.
That stability is one of the reasons Woolworths has been able to generate consistent earnings and dividends over many years.
The company also benefits from strong brand recognition, a nationwide store network, and significant scale advantages in procurement and logistics. These factors help support margins and reinforce its leadership position in the grocery sector.
For investors worried about market volatility, I think Woolworths remains one of the steadier businesses on the ASX.
Transurban Group (ASX: TCL)
Transurban operates a portfolio of major toll roads across Australia and North America, including key transport infrastructure in cities such as Sydney, Melbourne, and Brisbane.
What makes toll road operators attractive during uncertain periods is the predictability of their revenue. Many of Transurban's assets operate under long-term concession agreements that allow it to collect tolls for decades.
Traffic volumes can fluctuate slightly depending on economic conditions, but essential transport infrastructure tends to remain in demand over the long run.
Another appealing feature of Transurban is its inflation-linked toll structures. In many cases, toll prices increase each year in line with inflation or predetermined escalation formulas.
This can help protect revenue and cash flow even when inflation is elevated. For investors seeking stability and reliable income, Transurban's infrastructure assets can make it an appealing defensive holding.
Telstra Group Ltd (ASX: TLS)
Telstra is another company that tends to hold up relatively well during uncertain economic periods.
Telecommunications services have effectively become essential utilities in the modern economy. Mobile connectivity, broadband access, and network services are now fundamental parts of everyday life for both households and businesses.
Telstra's position as Australia's largest telecommunications provider gives it significant scale advantages and a broad customer base.
The company has also been investing heavily in its mobile network and digital infrastructure in recent years, helping reinforce its competitive position in the market.
For income-focused investors, Telstra's dividend is also an attractive feature. The company continues to generate strong cash flow and has been returning a meaningful portion of that to shareholders.
Foolish Takeaway
Bear markets can be uncomfortable, but they are also a normal part of long-term investing.
While share prices can still fall during broader market sell-offs, companies with resilient business models often recover faster and continue generating solid returns over time.
For investors seeking a bit more stability in their portfolios, Woolworths, Transurban, and Telstra are three ASX shares I think could offer some peace of mind.
