Monday morning portfolio summary
Your portfolio closed at $214,830 on Friday, down 1.7% for the week. The pullback was led by NVDA, which fell 5.5% after its Q4 earnings beat expectations but disappointed on forward guidance — $260B in market value was erased overnight. Meanwhile, AAPL continues to trade near highs after its record $143.8B revenue quarter.
- NVDA: Despite beating estimates, shares dropped on concerns about AI demand peaking and concentrated data center revenue (91% of total). The $4.5B H20 inventory charge from the October filing is still weighing on sentiment.
- AAPL: iPhone 17 demand drove a 23% surge in iPhone revenue to $85.3B last quarter. China sales up 38%. Still your largest holding at 31% of portfolio — above your 30% threshold.
- MSFT, GOOGL, AMZN, V, JPM, and 8 other positions showed no material evidence change this week.

Product posture
No pressure. No trade-now theatrics.
If software is meant to help you think clearly about stocks, it should not behave like it is trying to close you. Belfort stays read-only, keeps the evidence visible, and frames each material change around whether your thesis still stands.
Quiet rules
No pressure to trade
Belfort is read-only. It helps you see what changed and why it matters without turning every alert into a trade prompt.
No watchlist hype
A watchlist name is treated like a research question, not a lead magnet or manufactured urgency.
No urgency theater
Severity comes from the underlying event: a filing, transcript, article, or price move. Not from tactics designed to farm clicks.
How it works
A monitoring loop built for the stock-investor review cycle
Investor workflow
The product keeps watching owned and prospective names, then surfaces the changes that can affect conviction.
Track the names that matter
Track current holdings and research candidates separately, so owned exposure and watchlist curiosity stay clean.
Start with core stock positions, then track the companies you are studying before you own them.
Belfort watches what changed
Filings, earnings, news, and price signals are checked throughout the day against your list.
The loop stays quiet until a change is material enough to deserve an investor's attention.
Review whether the thesis stands
Alerts and briefs connect the event back to the thesis: what supports it, what weakens it, and what needs another look.
Read the summary first, then drill into the exact filing line, transcript excerpt, or article.
