Investor Checklist: 10 AI Investment Rules

1. CapEx >10% revenue — genuine AI infrastructure spend

2. P/S <15x infrastructure vs 25x+ models

3. Big Tech contracts >30% revenue mix

4. RPO >2 years (remaining performance obligations)

5. Position sizing max 10% single name

6. Sector allocation 15–25% portfolio maximum

7. Diversification 8–12 positions minimum

8. Stop-loss -25% on momentum leaders

9. Technical discipline RSI <70 (overbought)

AI vs Other Tech Sectors: Valuation Reality

2026 AI Stock Catalysts & Predictions

Infrastructure breakout (+80–150%): TSMC, ASML, MU (chip supply crunch)
Enterprise AI scaling (+100–200%): PLTR, SNOW, CRWD (contract backlog)
Tier-2 chip winners (+150–300%): AMD, Broadcom (NVIDIA alternatives)

Critical red flags:

• P/S >30x on <$5B revenue

• Single customer dependency >50%

• Persistent unprofitability Year 3+

• Hype without enterprise contracts

AI stocks represent the decade's defining trend. Infrastructure exposure (TSMC, AMD) offers superior risk/reward versus P/E 200x+ model developers. The trillion-dollar compute wave continues through 2028.
