Micro-Investing Strategies
Starting small doesn’t mean you can’t think big. Here are a few strategies to make the most of your $100 investment:
1. Automate Your Investments
Use recurring deposits to grow your portfolio over time. For instance, adding $10 weekly to your Acorns account means you’ll invest an extra $520 annually.
2. Diversify Your Portfolio
Spread your $100 across different asset types, such as ETFs, stocks, or themed funds. This reduces risk and increases your chances of consistent returns.
Trick: Use a 70/30 split — allocate $70 to a diversified ETF and $30 to a high-risk stock for balanced growth.
3. Compound Growth
Reinvest any earnings back into your portfolio to take advantage of compound interest. Over time, even small returns can snowball.
Calculation: If you invest $100 and earn a 7% annual return, your investment will grow to $196.72 in 10 years, assuming all returns are reinvested.
