It can be just as important to know which ASX shares to avoid as it is to know which ones to own when you are aiming to outperform the market.
That's because if you own shares that are likely to fall in value, your portfolio returns could be dragged down along with them.
With that in mind, let's look at three ASX 200 shares that analysts have named as sells this week, courtesy of The Bull. Here's what they are bearish on:

A2 Milk Company Ltd (ASX: A2M)
Catapult Wealth has named A2 Milk shares as a sell this week. It has fears that a recent product recall could damage its brand image in the China market. In addition, the financial services company highlights that supply chain disruptions are constraining product availability. It said:
This infant milk formula company recently initiated a voluntary recall of three small batches of contaminated product sold only in the United States. While the recall didn't impact the key Chinese market, it poses a reputational risk in a country and segment that is sensitive to brand reputation. A recent trading update revealed supply chain disruptions are constraining product availability despite strong underlying demand. The shares have remained under pressure since April when the company downgraded guidance in full year 2026.
Brambles Ltd (ASX: BXB)
The team at Red Leaf Securities is bearish on this logistics solutions company. As a result, it is recommending investors sell Brambles shares this week.
This is due to its belief that the ASX 200 share has gone from being a premium defensive compounder to a more challenged operational story. It explains:
This supply chain logistics giant has moved from a premium defensive compounder to a more challenged operational story following recent earnings and sales revenue downgrades. Disruptions in its United States pallet pooling network have exposed execution issues, resulting in higher costs. While the CHEP business model remains structurally sound, short term performance is weighed down by operational inefficiencies and inflationary pressures.
The downgrade cycle has shifted sentiment, with the market now questioning the sustainability of mid term growth expectations. Until execution stabilises and margins recover, Brambles lacks the earnings momentum required to justify a premium multiple, leaving risk skewed to the downside, in our view. The shares have fallen from $22.10 on May 15 to trade at $16.34 on May 28.
National Australia Bank Ltd (ASX: NAB)
Catapult Wealth has also named NAB shares as a sell this week. It was disappointed with the ASX 200 bank share's performance in the first half.
And with trading conditions getting tough, it isn't confident that NAB will be able to deliver on expectations. It said:
The bank's first half result in fiscal year 2026 was underwhelming, in our view. Investment loans account for about a third of residential lending. Proposed changes to negative gearing and capital gains tax are likely to reduce loan and property price growth, in our view. Given higher interest rates and affordability pressures, NAB may struggle to deliver the growth needed to support current expectations.
