| Ticker | Class | Amount | % |
|---|---|---|---|
| VTI | Index fund | $30,000 | 54.5% |
| AAPL | stock | $10,000 | 18.2% |
| VXUS | Index fund | $8,000 | 14.5% |
| MSFT | stock | $5,000 | 9.1% |
| BTC | crypto | $2,000 | 3.6% |
- VTI is 54.5% of the portfolio — concentration risk.
- AAPL is 18.2% of the portfolio — concentration risk.
- VXUS is 14.5% of the portfolio — concentration risk.
Target for most investors: 80%+ in low-cost index funds, a small satellite in individual stocks, and crypto ≤ 5% if held at all. Rebalance once a year so winners don’t silently drift into concentration risk.
