If you are looking for some new investment ideas, then it could be worth listening to what the team at Morgans is saying about these top ASX stocks.

The broker has named them both as buys and is tipping them to rise by around 15% to 20%. Here's what you need to know:

GQG Partners Inc (ASX: GQG)

This global boutique asset management company could be a top ASX stock to buy according to the broker.

It was pleased with its full year results and believes there's still plenty more to come. So, with GQG's shares trading on undemanding multiples, the broker thinks that now could be the time to invest. It said:

GQQ reported revenue +% and NPAT +53% on pcp to US$431.6m. The result slightly beat expectations across the board, with operating profit delivering ~11% HOH growth to US$303.7m. The flows outlook remains solid at the group level, with acceleration of inflows in the wholesale channel looking set to continue. Recent investment underperformance in the EM strategy could see some outflow risk in the strategy.

The dividend payout policy range has changed to 50-95%. The group stated there is no current intention to vary the payout, however this allows the flexibility to build capital for strategic opportunities if required. GQG still has meaningful growth based on the current fund offerings; with longer-term optionality from leveraging the distribution capability (PCS; additional teams). We view the valuation as attractive at ~10x FY25 PE. Add maintained.

Morgans has an add rating and $2.85 price target on its shares. This implies potential upside of 15% for investors. In addition, an 8% dividend yield is expected in FY 2025.

Northern Star Resources Ltd (ASX: NST)

This gold miner could be another top ASX stock to buy according to Morgans.

It was pleased with its "solid" half year results, highlighting its strong realised gold price and low costs. The broker said:

1H25 earnings were solid, driven by a strong gold price with underlying EBITDA exceeding expectations by 3%. 804koz of gold was sold at an average realised price of A$3,562/oz, with an AISC of A$2,105/oz. Balance sheet is strong, with A$265m in net cash and a record interim dividend of A$0.25 per share beating Morgans' forecast of A$0.21 per share. We have updated our model to incorporate changes in spot gold price (US$2,850, previously US$2,600).

Morgans has put an add rating and $21.57 price target on its shares. This suggests that they could rise 22% over the next 12 months.
