Let me analyze this portfolio and the investment strategy:
## Investment Strategy
The user wants to invest in suppliers to AI/GPU needs, specifically:
- NOT power companies or cloud computing or Nvidia
- Looking for something needed for LLM use cases
- Interested in downstream/esoteric suppliers like memory or other components
## Current Portfolio Analysis
Looking at the holdings:
1. **ONTO** - Onto Innovation: Semiconductor metrology/inspection equipment - Good fit
2. **VRT** - Vertiv Holdings: Data center cooling and power management - Good fit
3. **RMBS** - Rambus: High-speed interface chips and security IPs - Good fit
4. **MU** - Micron: Memory chips (DRAM, NAND) - Perfect fit for strategy
5. **AMKR** - Amkor Technology: Semiconductor packaging/testing - Good fit
6. **MRVL** - Marvell: Data infrastructure semiconductor solutions - Good fit
7. **AEHR** - Aehr Test Systems: Semiconductor test equipment - Good fit
The portfolio is extremely well-aligned with the strategy - all holdings are AI/GPU supply chain players.
## Market Conditions
- Markets are down significantly today (S&P -2.06%, NASDAQ -2.39%)
- VIX is up 9.67% to 20.66, indicating increased volatility
- Fed expected to hold rates through March
- Recent news shows:
- AI funding continues (OpenEvidence raising $250M)
- Memory chip shortage continues (Cramer bullish on MU)
- Cooling solutions becoming critical for AI data centers (mentioned in MU news)
## Position Analysis
**Winners:**
- AEHR: +10.4% (largest position by shares)
- RMBS: +9.4%
- MU: +7.2% (largest position by value)
- ONTO: +6.9%
- VRT: +5.5%
**Losers:**
- AMKR: -6.2% (wash sale warning!)
- MRVL: -4.1%
## Tax Considerations
- All positions are short-term (less than 1 year)
- Total unrealized gains: $5,675.13
- Total unrealized losses: $939.28
- **AMKR has wash sale warning** - cannot add to this position
## Cash Deployment
- Cash available: $8,867.12
- Portfolio value: $105,360.11
- Cash is 8.4% of portfolio - reasonable buffer
## Trade Recommendations
The pullback presents a chance to add to MRVL at a discount since it's down 4.1% and fits the AI infrastructure thesis around data center switching and processing. I should avoid AMKR due to the wash sale restriction, but can explore new positions in complementary areas like memory controllers, advanced packaging, thermal management, or high-bandwidth interconnects. The winners are performing well and aligned with strategy, though AEHR might warrant trimming given it's the largest position by share count and already up 10.4%.
For cash deployment, I'd aim to put 70-80% to work given the market conditions and available opportunities.
