Markets do not always move in straight lines.
Even high-quality businesses can see their share prices drift lower during periods of uncertainty. For long-term investors, those moments can create opportunities to accumulate blue chip ASX shares at more attractive levels.
Here are three quality names I would be comfortable buying now.

ResMed Inc. (ASX: RMD)
The first blue chip ASX share I would consider buying is ResMed.
ResMed is a global leader in sleep disorder treatments. Its devices and cloud-connected software help millions of patients manage conditions such as sleep apnoea and chronic obstructive pulmonary disease.
But the company is still only scratching at the surface of its market opportunity. Management estimates that there are over 1 billion sufferers of sleep apnoea globally. However, the majority of these people don't know they have the condition.
As awareness grows, ResMed stands to benefit greatly as the clear market leader.
In addition, the company has been investing in digital health platforms that link devices to data, improving patient outcomes and strengthening recurring revenue streams. Combined, this blue chip appears well-placed to continue its growth over the next decade and beyond.
Macquarie Group Ltd (ASX: MQG)
Another blue chip ASX share worth a look is Macquarie Group.
Macquarie has built a global reputation in infrastructure, asset management, and specialist financial services. It benefits from exposure to long-term trends such as renewable energy, digital infrastructure, and alternative assets.
Unlike traditional banks, Macquarie's earnings are more diversified across geographies and business lines. This can provide resilience across economic cycles.
With strong capital management and a track record of reinvesting into growth areas, Macquarie remains one of the more dynamic blue-chip names on the ASX.
Wesfarmers Ltd (ASX: WES)
A final blue chip ASX share I would consider this week is Wesfarmers.
It owns businesses such as Bunnings, Kmart, Target, Priceline, Silk Laser, WesCEF, and Officeworks. These are well-known brands with significant scale advantages in their respective markets.
Bunnings in particular has demonstrated pricing power and operational discipline over many years. Meanwhile, Wesfarmers continues to invest in growth areas, including lithium and health, while maintaining a strong balance sheet.
The company's combination of retail leadership, capital allocation discipline, and diversification could make it a reliable long-term holding.
