Learning Log — Plain-English explainers for the signals we trade.

The signals EMI uses every cycle, written for traders who already understand expected value. 13D filings. The 22 activist desks. Convergence math. The trader-grade frameworks behind every alert — published for free.

Reading list

Start here.

  1. FILINGS

    What is a 13D filing?

    The mandatory SEC disclosure activists must file within 10 days of crossing 5% ownership. The single highest-signal public filing in U.S. markets — and how EMI alerts on every one within 5 minutes.

  2. FUNDS

    The 22 activist hedge funds EMI tracks

    Elliott, Pershing Square, Icahn, Starboard, ValueAct and 17 more. Who they are, what they buy, and why their filings move markets.

  3. CONVERGENCE

    What is a convergence signal?

    When two or more independent signal sources point at the same ticker in the same direction. Why EMI's Tier-A alerts are reserved for these — and why single-source alerts go to the watchlist.

  4. PIPELINE

    The 12-phase intelligence pipeline

    From article ingest to graph neural network to alert dispatch. The path every signal takes — and the three integrity gates a trade has to clear before it reaches you.

  5. RECEIPTS

    What's inside a casefile?

    The public file behind every alert: evidence spine, decision trace, broker fills, and the autopsy if it lost.

  6. LOSSES

    How EMI handles losses

    Dual-horizon postgame, four loss buckets, and why we publish the autopsies. Losses are where the model learns.
