Are you looking for big returns for your investment portfolio in 2025? (Who isn't?!)

Well, if you are, it could pay to look at the three ASX 200 shares named below.

That's because analysts have put buy ratings on them and are tipping them to rise very strongly from where they currently trade. Here's what sort of returns could be on offer with these shares:

Endeavour Group Ltd (ASX: EDV)

The team at Goldman Sachs thinks that this drinks giant could be an undervalued ASX 200 share.

It is the owner of the BWS and Dan Murphy's brands, as well as a large network of hotels across the country.

It thinks the company's shares are good value at current levels. Particularly given the low implied valuation of its Hotels business. It said:

We continue to believe that the company's core businesses are high quality (evidenced by Retail share gains and Hotels F&B margin improvement). The current share price implies that the Hotels business is trading on FY25 EV/EBIT of 2.9x (pre AASB16), excluding A$1B of freehold property assets.

Goldman has a buy rating and $5.50 price target on its shares. This implies potential upside of 31% for investors from current levels. In addition, the broker is forecasting a dividend yield of 4.8% in FY 2025. This boosts the total potential return to over 36%.

Johns Lyng Group Ltd (ASX: JLG)

The team at Morgans thinks that Johns Lyng could be an ASX 200 share to buy. It is an insurance building and restoration services company.

The broker was pleased with the announcement of a new acquisition. It likes that the deal provides further scale to the group's domestic operations. It explains:

We see Keystone as highly complementary to JLG's existing IB&RS business, which provides further scale to the group's domestic operations (particularly within QLD) as well as increased exposure to commercial and large loss claims work. Incorporating Keystone into our forecasts see our EBITDA upgraded by ~7% in FY25-27F, while increased level of debt to fund Keystone (and SSKB & Chill-rite), sees our EPS forecasts increase ~4%.

Morgans has an add rating and $5.10 price target on the ASX share. This suggests that its shares could rise approximately 40% from current levels.

PEXA Group Ltd (ASX: PXA)

Finally, Goldman Sachs also thinks that PEXA could be a great ASX 200 share to buy now.

It is the leading electronic lodgement network operator (ELNO) facilitating electronic lodgement and settlement of property transactions in Australia.

Goldman highlights that it sees the company's technology as core digital infrastructure with a relatively defensive growth profile supported by inflation-linked price increases mid-cycle property transaction growth. It said:

We believe PEXA's market share is resilient despite interoperability being an initiative to bring more competition to the industry, and forecast incremental share gains over the cycle. We see significant upside from the UK and PEXA Digital Growth (PDG), opening a combined incremental TAM of A$1bn, but given the early stage nature of both businesses, we remain cautious over potential execution risks

The broker has a buy rating and $16.00 price target on its shares. This implies potential upside of 23% for investors between now and this time next year.
