The Motley Fool, a financial services company, aims to make the world smarter, happier, and richer through various investing solutions, market analysis, and education. The article discusses how an individual with $100 to invest regularly could achieve considerable growth over time, possibly becoming a component of a millionaire-maker portfolio.

The article explores different investment strategies based on risk tolerance and goals. For those wanting minimal risk, investing in an ETF tracking an index like the S&P 500 is recommended, historically yielding significant annualized returns. For slightly higher risk with potentially better returns, an ETF that tracks a growth index, like the Vanguard S&P 500 Growth ETF, is suggested.

Investors willing to take on more risk might consider growth stocks such as SoFi Technologies or Axon Enterprises, especially if already well-diversified. Another strategy for a small investment is purchasing shares of established companies like Amazon or Berkshire Hathaway, possibly buying fractional shares if necessary. Alternatively, Walmart could be a straightforward choice with its relatively lower stock price, under $100.

Lastly, for those seeking passive income, options such as dividend stocks or ETFs are recommended. Overall, the article underlines diverse approaches aligning with different investor profiles, emphasizing long-term growth potential even with modest, regular investments.
