The goal
Build a repeatable process that reduces emotion and improves decisions over time.
The 5 steps
Step 1
Determine your investing approach
Choose a strategy that matches your time, temperament, and goals — and commit to it.
Step 2
Decide how much to invest
Keep emergency funds separate. Size your stock allocation with volatility in mind.
Step 3
Open a brokerage account
Pick a broker with strong reporting, usability, and support — not just low fees.
Step 4
Choose your stocks carefully
Diversify, invest in understandable businesses, and avoid excessive volatility early on.
Practice step 4 on real data
Open any stock page in the app for fundamentals, valuation and an AI forecast with its confidence label.
Step 5
Continue with discipline
Consistency matters more than perfect timing. Process beats prediction.
Quick principles
- Markets reward preparation, not prediction.
- Risk management matters as much as returns.
- Avoid emotional decisions and chasing price movement.
- Learn the basics: diversification, volatility, and key metrics.
Rule of 110 (allocation)
A common guideline: subtract your age from 110 to estimate the percentage of your portfolio allocated to stocks. Adjust based on your goals and risk tolerance.
A 7-step starter checklist
If you only do one thing after reading this page: follow a checklist before every buy.
- Define your time horizon (days/weeks vs years).
- Pick a position size rule before you find a stock.
- Set an invalidation level (where you’ll admit you’re wrong).
- Screen for quality + momentum (or your preferred edge).
- Check broader market regime (risk-on vs risk-off).
- Plan the entry: trigger + limit + patience.
- Write down the plan—then execute it the same way.
Terms worth knowing
A few concepts that show up everywhere in investing.
- Volatility
- How much price moves. Bigger swings = bigger risk.
- Drawdown
- Peak-to-trough decline. Your real enemy.
- Diversification
- Reducing single-name risk across holdings.
- Time horizon
- How long you intend to hold—and why.
