6 Rules for Investing Small
Simple principles that apply whether you have $5 or $500
Start with what you can lose
Only invest money you won't need in the next 1–3 years. Even $5/week adds up to $260/year.
Buy index funds first
ETFs like VTI or SPY give you instant diversification across hundreds of companies for one low price.
Use fractional shares
You don't need $175 to own Amazon. Buy $5 worth. Most free apps let you do this.
Invest consistently — not perfectly
Put in the same amount every week or month no matter what the market does. This is called dollar-cost averaging.
Avoid chasing hype
If everyone is talking about a stock on social media, the easy money is probably already gone.
Reinvest your gains
Turn on dividend reinvestment (DRIP) so your earnings automatically buy more shares — compounding works magic over time.
