BULLISH Verdict
Momentum breakout confirmed; data center demand intact.
Bull Case
Blackwell GPU ramp accelerating; hyperscaler capex in early innings. Gross margins recovering toward 75%+ — pricing power intact.

AI Investment Snapshot
NVDA Nvidia Corp.
$118.42 +2.8% today
Overall Bullish
Bull case
AI infrastructure demand remains structural; Blackwell ramp accelerating. Data center capex from hyperscalers continues through 2025. Revenue consensus may be conservative — a beat/raise cycle is likely. Dominant position in CUDA ecosystem creates high switching costs and pricing power.
Bear case
Valuation stretched at 38× forward earnings with near-zero margin for guidance miss. Export restriction risk re-escalating on China chip rules. Competitive pressure from AMD and custom silicon (AWS Trainium, Google TPU) starting to compress market share at the margin. Any macro slowdown hits capex budgets first.
Entry zone $112–$116
1-month target $134
Stop loss $104
Risk / reward 1 : 2.1
Sigma’s take

Strong secular tailwind but buying here means paying full price for the story. Wait for the $112–$116 zone on any pullback — that's where risk/reward becomes attractive. Blackwell shipment cadence is the key variable to watch: a strong Q2 print accelerates the bull case materially.

The analyst workflow

The framework top analysts use.
Now automated.

The old way
  • Jump between charts, filings, news, screeners, and notes. Miss things anyway.
  • Ask generic AI questions that ignore your portfolio and live price context.
  • Forget old targets and stops. Never know if your thesis was actually right.
The Sigma way
  • One place: stock, portfolio, sector, earnings, or market brief — structured output every time.
  • Analyst-grade methodology: valuation, scenario framing, risk factors, position sizing.
  • Every prediction logged and graded — so your conviction compounds over time.
Verifiable proof

Every prediction logged.
Including the misses.

No tool in this space shows you when it was wrong. Sigma logs every AI price target and verdict publicly — graded against what actually happened. That's accountability, not marketing.

Don't take our word for it

We'd rather show you the record
than quote ourselves.

Most landing pages put words in customers' mouths. We'd rather point you at the ledger — every call Sigma stands behind, scored against what actually happened. Read it before you trust a single claim on this page.

Every official call is logged the moment it's made — with the entry price and a scoring date fixed up front. No backdating, no hindsight.
Made, then scored
A commitment, not a claim
Misses render exactly like hits — same size, same prominence, the loss shown plainly. A wrong call is never quietly deleted.
Misses shown, not hidden
Append-only by design
No headline hit-rate until there's enough scored calls to mean something. We won't show you a "100% (3 calls)" number to look good.
Honest with the math
Statistics, not spin

Questions

Know what you are buying.

Is this financial advice?
No. Sigma is research software. It helps structure market data, risks, and scenarios so you can make your own decisions.
Why not just ask a generic AI tool?
Sigma adds live market context, saved profile data, portfolio context, alerts, and prediction tracking around each answer.
Can I use it for earnings?
Yes. Pro and Elite users can run pre-earnings previews and recent earnings assessments with EPS history and reaction framing.
Can I cancel?
Yes. Paid plans are monthly. Billing is managed through the account billing portal.
Is my data secure?
Passwords are hashed with bcrypt. Sessions use JWT. Any keys you bring (such as your own Anthropic key) are encrypted at rest with AES-256-GCM. API keys you generate are stored as SHA-256 hashes, never as plaintext. We do not sell or share personal data for advertising.
Where does the real-time market data come from?
Quotes, fundamentals, news, and insider activity stream from regulated US data providers with on-our-side caching to keep latency low. Coverage focuses on US-listed stocks and ETFs.
Which AI model does Sigma use?
Sigma is powered by Anthropic Claude. Heavier analyses run on Sonnet for reasoning; lighter routing tasks run on Haiku for speed and cost. Elite users can plug in their own Anthropic API key for unlimited usage.
Do you support markets outside the US?
Today Sigma is focused on US-listed stocks and ETFs (NYSE, Nasdaq, AMEX). Coverage of other markets is on the roadmap and will be enabled as data partners are added.
