Investing in the stock market can be intimidating for beginners.

Do you chase speculative stocks that promise quick riches, or do you get rich slowly?

Well, history has shown that the most reliable way to build long-term wealth is by focusing on high-quality businesses with strong fundamentals, competitive advantages, and solid growth prospects.

For those just starting out, here are five quality ASX shares that analysts rate as buys and could serve as a strong foundation for a portfolio.

Goodman Group (ASX: GMG)

The first quality ASX share to look at is Goodman Group. It is one of the world's leading industrial property companies, with a focus on data centre and logistics and warehouse facilities. With the rise of e-commerce and global supply chains, demand for high-quality logistics infrastructure has skyrocketed, benefiting Goodman significantly. The company has an impressive portfolio of properties, strong relationships with blue-chip tenants like Amazon (NASDAQ: AMZN), and a solid track record of long-term value creation.

Citi has a buy rating and $40.00 price target on its shares.

REA Group Ltd (ASX: REA)

If you've ever browsed realestate.com.au, you've used one of REA Group's platform. The company is the undisputed leader in online property advertising in Australia, generating strong earnings from real estate agents and home sellers looking to get their listings in front of buyers. Property market cycles may fluctuate, but REA's dominant position and pricing power make it a high-quality business with strong long-term prospects.

ResMed Inc. (ASX: RMD)

Another ASX share for beginners to look at is ResMed. It is the leading player in the sleep apnoea and respiratory care space, with a presence in over 150 countries.
