Analysts say these excellent ASX shares offer double-digit returns

Are you looking for ASX shares to buy this week? If you are, then the two listed below could be worth considering.

That’s because both have been rated as buys and tipped to offer big returns for investors. Here’s what analysts are saying about them:

NextDC Ltd (ASX: NXT)

The first ASX share to consider is NextDC. It provides colocation services to local and international organisations from its growing collection of world-class Tier III and Tier IV data centre facilities across Australia.

Goldman Sachs is bullish on the company and believes it is well-placed for growth. Particularly given the artificial intelligence (AI) boom, which is expected to drive increased demand for data centre capacity. It said:

We believe the DC industry will benefit from a ‘third wave of demand’, with generative AI requiring 5-10x more compute vs. traditional search.

Goldman currently has a buy rating and a $14.96 price target on its shares. This compares to the latest NextDC share price of $12.78.

Sonic Healthcare Limited (ASX: SHL)

Another ASX share that could be a buy is Sonic Healthcare. It is a healthcare company offering pathology, diagnostic imaging, and primary care medical services.

Citi is a fan of the company and believes it is well-placed for growth in the coming years. This is thanks partly to its strong balance sheet and acquisition opportunities in a fragmented industry. It said:

SHL announced a binding agreement to acquire Diagnosticum, a laboratory group in southeast Germany with 15 labs and 25 pathologists. SHL will pay €190m (cash, debt free) / ~A$310m. […] The transaction is in-line with the company’s long-term strategy of deploying capital through acquisitions (>40 since FY07). SHL estimates that the top-5 players in Germany only have a 40-50% market share (SHL being #1), leaving room for further consolidation. We rate SHL Buy,

Citi has a buy rating and a $40 price target on its shares. This compares to the latest Sonic Healthcare share price of $35.54. In addition, Citi is expecting ~3% dividend yields this year and next.
