What are insiders and institutions doing with Nvidia stock?
Nvidia insiders have been net sellers with zero open-market buys, while the early 13F filers lean toward adding, per SentiSense’s SEC filing data (Form 4s from Jul 6 to Oct 4, 2026; 13Fs for the quarter ended Sep 30, 2026).
- Insider sales: 22 trades, $765.6M. Director Mark Stevens: $744.6M of it.
- Insider buys: none. 9 of the 22 sales were under 10b5-1 plans.
- Institutions adding: 14 of the top 20 filers. 13 increased, 1 new (Polaris Financial, $37.2M).

What you can ask
Four questions from one conversation with SentiSense in Claude, in the order we asked them.
01 Start broad
What are the stocks with the best options positioning before the market opens tomorrow, and find me the stocks too with the highest analyst upside potential.
Cognizant, Synchrony and Viavi led on bullish options positioning. On analyst price targets, Fermi led with roughly 325% implied upside, followed by Viking Therapeutics at 217%. The two lists shared almost no names.
Tools: Options, Screener
02 Cross two signals
Do we have any information we can use from the sentiment scores, and how does this correlate with the latest analyst ratings?
Across 1,049 screened stocks, 59% of those with bullish sentiment carried buy ratings from at least 70% of their analysts, against 37% of those with negative sentiment and 46% overall. The signals move together, loosely, and Claude noted this is a group comparison, not a correlation coefficient.
Tools: Screener, Analyst Ratings
03 Put it together
Putting it all together, what are the most interesting stocks positioned for this week?
Five names where the signals stack up or clash, each with what stands out and the catch. Two of them:
- Uber: two insiders bought $15.3 million of stock over 90 days and more than 70% of analysts rate it a buy. The catch: its sentiment reading was bearish.
- Applied Digital: reports on Wednesday, October 7, with analyst targets implying 162% upside and call-heavy options positioning. The catch: muted sentiment going into the report.
Tools: Earnings Calendar, Smart Money, Options, Analyst Ratings
04 Drill into one stock
How is Amazon doing when you compare it to this set above? Amazon has the best sentiment and one of the best analyst upsides?
Amazon had the strongest sentiment of the group and the highest analyst buy ratio, 57 of its 59 analysts. Claude corrected the premise: implied upside to analyst targets was 31%, so what ranked near the top was the buy ratio, not the upside. Insiders had sold $364.8 million over the period, all under pre-scheduled trading plans.
Tools: Analyst Ratings, Options, Smart Money
SentiSense data as of the October 2, 2026 close and the October 4 batch. Answers condensed from Claude’s replies; every figure came from a tool call.
Watch it on YouTube: the four questions above (55 s), and best sentiment with options positioning (29 s).
Eleven tools, picked for you
Ask in plain English and your assistant chooses the tool. A question to start with for each one:
The market
“What’s the market mood right now?”
Market Mood“Find stocks under $10B market cap with rising sentiment.”
Screener“Who reports earnings this week, and when does NVDA report?”
Earnings Calendar
One stock
“Give me a snapshot of NVDA with its SentiSense Score and recent news.”
Stock Snapshot“What’s the SentiSense Rating on MSFT, and which dimension is weakest?”
SentiSense Rating“What are the biggest stories on TSLA this week?”
News“Pull ten years of annual revenue and free cash flow for AAPL.”
Financials“Who runs TSLA, which products does it sell, and who are its peers?”
Entity Brief
Smart money and the Street
“Which institutions are buying and selling AAPL?”
Smart Money“What do analysts think of TSLA, and what are the price targets?”
Analyst Ratings“What’s the options sentiment on NVDA, and is IV high right now?”
Options
A twelfth tool, sentisense_health, checks the connection and uses no quota. Quotes are delayed 15 minutes; sentiment, Market Mood, news and options are recomputed on a schedule. Coverage spans the most-watched US stocks and the ETFs we track.
Free to start
Every tool works on a free account. The connector follows the tier of the account you sign in with, so upgrading needs no reconnect.

Does the connector work on Claude’s free plan?
Yes. Claude’s Free plan allows one custom connector, and a free SentiSense account is enough to sign in to it.
What can I ask?
Questions about the US market or a single stock: market mood, a stock’s snapshot and news, the SentiSense Rating, analyst ratings and price targets, institutional 13F holdings and flows, options positioning, the earnings calendar, reported financials, a stock and ETF screener, and the people, products and peers behind a ticker. Ask in plain English; your assistant picks the tool.
Is the connector read-only?
Yes. All eleven tools read data. Nothing in the connector trades, writes or touches a brokerage account. You sign in with OAuth, so there is no API key to paste, and the connection uses the tier of the SentiSense account you signed in with.
What does the free tier include, and what does PRO add?
Every tool works on a free account: 1,000 calls a month, shared with your API quota, at up to 30 a minute. Market Mood and news return full results; stock snapshots, smart money, options, the earnings calendar and the screener return preview-depth data. PRO adds full data on every tool, no monthly cap, and up to 300 calls a minute.
Why did my AI answer without calling SentiSense?
Name the connector in the question, for example: “Using SentiSense, what are insiders doing with Nvidia stock?” An assistant can answer from its own knowledge when a question does not clearly call for a tool.
Can I use the same data from my own code?
Yes. The connector is a read-only slice of the SentiSense REST API. A free API key gives your own code the same data, with Python and Node SDKs and published agent skills.
Building your own agent or app? The same data is a REST API, with Python and Node SDKs and a free key.
