## The Basics

Most investment mistakes stem from abandoning proven methods in favor of emotions or shortcuts. The Manifest Method provides guardrails against these errors, but only if you follow it consistently.

Successful investing requires discipline to stick with quality companies bought at reasonable prices. When investors deviate from this approach—whether from fear, greed, or impatience—they typically underperform the market.

## Most Common Mistakes

### Quality Mistakes
- **Buying low-quality stocks** (Quality Rating below 65) because they're cheap
- **Ignoring red flags** in financial statements or business fundamentals
- **Chasing momentum** without analyzing company quality

### Pricing Mistakes
- **Buying above the Sweet Spot** because you "love" the company
- **Waiting for perfect prices** and missing good opportunities
- **Ignoring PAR calculations** and overpaying for growth

### Emotional Mistakes
- **Panic selling** during market downturns
- **Following hot tips** instead of doing your own analysis
- **Falling in love** with stocks and ignoring deteriorating fundamentals

### Portfolio Mistakes
- **Over-diversification** (holding 30+ stocks) that dilutes returns
- **Under-diversification** (fewer than 10 stocks) that concentrates risk
- **Sector concentration** without realizing it

## On the Platform

Manifest's tools help you avoid these mistakes:

- **Quality Ratings** prevent you from buying poor companies
- **PAR calculations** show when stocks are overpriced
- **Sweet Spot indicators** highlight optimal buying opportunities
- **Portfolio dashboards** reveal concentration risks

## How to Avoid These Mistakes

3. **Use stop-losses** or selling criteria to limit emotional decisions
4. **Review holdings quarterly** using [Portfolio Reviews](/guide/making-decisions/portfolio-design)
