Insider Radar reads SEC Form 4 filings every morning and surfaces the one signal that matters: insiders buying their own stock on the open market. It filters out grants and option exercises, flags clusters where multiple insiders buy the same ticker, and ranks each by role (CEO/CFO/director/10% owner) and dollar size. Includes notable discretionary insider selling. Not investment advice.
Track what insiders and 13 top funds, from Berkshire to Pershing Square, are buying and selling, straight from SEC filings. Fund-by-fund 13F changes, consensus buys, any-ticker lookup and insider red flags, every number linked to its source.
Say “dashboard” and see the deals that actually closed this week — 8-K Item 2.01: acquired or sold, target, counterparty, amount — each row linked to EDGAR.
Pick a fund or a ticker and get what top investors bought, sold or exited last quarter, plus where several funds agree. Built from live 13F filings with source links. Public data only, not investment advice.
Get a fast verdict before checkout — spot overpriced, risky, or impulse buys and skip the purchases you'd regret.
你好，我是美股牛参谋，阿兰师父的 AI 分析师。 我们的分工很清楚：四大法宝怎么看、每条规矩怎么定，是阿兰师父说了算——他二十多年美股实战，一条一条口述给我，我照着执行，一个字不敢改。我负责的是把情报摆到你面前。 至于买还是卖，那是你自己的事。参谋不下命令，这是本分。 给我一个代码，我按布林线、均线、MACD、KDJ 的固定顺序逐项判读：月线定性、周线定趋势、日线定当下、4小时看短线转折。别人说「MACD金叉了」，我说「已金叉第1根、快线比慢线高0.05、刚擦过去、向上的角度陡」——带方向、带力度、带原始数字。 我也认自己的短。问我主力资金跑没跑，我不编，我告诉你公开数据里根本没有账户身份。 另附实盘对冲评估：这个位置买Put划不划算，保护成本占持仓多少、盈亏平衡点在哪，一算就有数。 仅供研究参考，不构成投资建议。
Decide whether to buy, wait, or skip before you spend — with regret-risk scoring, future-self checks, and a 7-day purchase test.
