On March 8, 2025 I decided to invest in the stock market. With all the buzz about AGI I thought, why not let AI invest this money for me. Of course, I don't have $20K I'm willing to play with but I do have the ability to write down that I do and keep track so we'll invest this virtually. # March 2025 At the moment, OpenAI's GPT-4.5 is a leading model, so I used that. Here's how it invested my money: | | | | | | | |---|---|---|---|---|---| |Stock|Ticker|Allocation|Current Price|Quantity Purchased|Total Cost| |NVIDIA Corporation|NVDA|$8,000|$112.69|71 shares|$7,998.99| |Microsoft Corporation|MSFT|$4,000|$393.31|10 shares|$3,933.10| |Alphabet Inc.|GOOGL|$4,000|$173.86|23 shares|$3,998.78| |Broadcom Inc.|AVGO|$2,000|$194.96|10 shares|$1,949.60| |Palantir Technologies Inc.|PLTR|$2,000|$84.91|23 shares|$1,952.93| Weird that it's all tech stock, but ok. I'm letting it make the decisions. This allocation utilizes $19,833.40 of my $20,000, leaving a remaining balance of $166.60. Monitoring and Adjustment Schedule: • Quarterly Reviews: Evaluate portfolio performance every three months. • Semi-Annual Rebalancing: Adjust allocations every six months to maintain desired investment proportions. # June 2025 As of the market close on **June 14 2025**, here’s where each position stands: | **Stock** | **Ticker** | **Qty** | **Purchase Price (Mar 8 ’25)** | Current Price (Jun 14 ’25) | **Cost Basis** | **Market Value** | **Gain / (Loss)** | **Gain %** | | -------------------------- | ---------- | ------- | ------------------------------ | -------------------------- | --------------- | ---------------- | ----------------- | ----------- | | NVIDIA Corp. | NVDA | 71 | $112.69 | $141.97 | $ 7 998.99 | $ 10 079.87 | **+$ 2 080.88** | **+26.0 %** | | Microsoft Corp. | MSFT | 10 | $393.31 | $474.96 | $ 3 933.10 | $ 4 749.60 | **+$ 816.50** | **+20.8 %** | | Alphabet Inc. | GOOGL | 23 | $173.86 | $174.67 | $ 3 998.78 | $ 4 017.41 | +$ 18.63 | +0.46 % | | Broadcom Inc. | AVGO | 10 | $194.96 | $248.70 | $ 1 949.60 | $ 2 487.00 | **+$ 537.40** | **+27.6 %** | | Palantir Technologies Inc. | PLTR | 23 | $84.91 | $137.40 | $ 1 952.93 | $ 3 160.20 | **+$ 1 207.27** | **+61.8 %** | | **Totals** | | | | | **$ 19 833.40** | **$ 24 494.08** | **+$ 4 660.68** | **+23.5 %** | _Prices pulled from live market data on June 14 2025._ **Portfolio recap** - The virtual $20 000 is now worth **$24 494**, a **23.5 %** return in just over three months. - Biggest winner so far: **Palantir** (+61.8 %). - Lagging but still positive: **Alphabet** (+0.46 %). - The un-invested cash balance remains **$166.60**. Now o3 is available, so using the leading model, I'll let it continue deciding for me. Here's what it did > I’ve trimmed the two positions that had become outsized or especially volatile (NVIDIA and Palantir) and parked the proceeds in cash (“Bank”) until the next quarterly review. Everything else is a **hold** for now. |**Stock / Cash**|**Ticker**|**Action**|**New Qty**|**Price (14 Jun ’25)**|**Market Value**|**Portfolio Weight**| |---|---|---|---|---|---|---| |NVIDIA Corp.|NVDA|**Trim 21 shares**|**50**|$141.97|$7,098.50|33 %| |Microsoft Corp.|MSFT|Hold|10|$474.96|$4,749.60|22 %| |Alphabet Inc.|GOOGL|Hold|23|$174.67|$4,017.41|19 %| |Broadcom Inc.|AVGO|Hold|10|$248.70|$2,487.00|11 %| |Palantir Tech.|PLTR|**Trim 13 shares**|**10**|$137.40|$1,374.00|6 %| |**Bank (cash)**|—|Proceeds from trims|—|—|**$4,767.57**|19 %| |**Total**|||||**$24,494.08**|100 %| _Prices reflect the latest close on June 14 2025._ --- > **Why these moves?** > > - **Risk balance** – NVIDIA had crept above 40 % of the portfolio, and Palantir’s 60 % run-up made it both overweight and high-beta. Trimming locks in gains and reins in single-stock risk. > > - **Cash buffer** – Setting ~19 % aside gives flexibility to: > - Re-enter beaten-down opportunities if the AI trade cools. > - Broaden into non-tech sectors or a broad-market ETF (e.g., VOO) during the next rebalance. > > **What’s next?** > > 1. **Watchlist expansion** – Over the next quarter I’ll screen for quality names outside mega-cap tech (health-care, renewables, industrial automation) so the portfolio isn’t a one-theme story. > 2. **September review** – If cash is still idle, we’ll redeploy according to then-current valuations and momentum. > 3. **October semi-annual rebalance** – Formal check that no single position exceeds ~30 % and tech stays below ~60 % of total assets. # September 2025 # December 2025 # March 2026 Scheduled Check-Ins: • First Check-In: June 8, 2025 • Second Check-In: September 8, 2025 • Third Check-In: December 8, 2025 • Fourth Check-In: March 8, 2026
