## What's an Apify Actor?

Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.
Actors are written with capital "A".

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.
The best way to integrate Actors is as follows.

In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js.md):

```bash
npm install apify-client
```

In Python projects, use official [Python client library](https://docs.apify.com/api/client/python.md):

```bash
pip install apify-client
```

In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md):

````bash
# MacOS / Linux
curl -fsSL https://apify.com/install-cli.sh | bash
# Windows
irm https://apify.com/install-cli.ps1 | iex
```bash

In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/platform/integrations/mcp.md).

If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md).

For usage examples, see the [API](#api) section below.

For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt).


# README

## SEC Activist 13D/13G Monitor

Monitors SEC EDGAR for new **Schedule 13D/13G filings by activist investors** and — unlike generic EDGAR scrapers — flags **brand-new campaigns**: the first 13D an activist has *ever* filed on a given target company.

Default target: **Saba Capital Management** (CIK 1510281), the most active closed-end fund activist (~10 new campaigns per year). Works with any filer CIK: Bulldog Investors, Karpus, City of London, or any investor you want to track.

### Why the new-campaign flag matters

A 13D filing stream is noisy: most filings are amendments or repeat filings on companies the activist already targeted. The actionable event is the **first original 13D on a new target** — that is when a campaign starts.

This actor computes the flag against the activist's **complete filing history** (not just the lookback window), using the same event definition as a published-style event study of 121 activist CEF campaigns (2015–2026): targets outperformed a closed-end fund basket by **+2.65% after 63 trading days (t=4.3)** and **+3.6% after 126 days**, with the discount closing in 81% of campaigns. Past performance does not guarantee future results — see the disclaimer below.

### Input

| Field | Default | Description |
|---|---|---|
| `activistCiks` | `["1510281"]` | Filer CIKs to monitor (Saba Capital by default). Find a CIK via [EDGAR company search](https://www.sec.gov/cgi-bin/browse-edgar). |
| `lookbackDays` | `45` | Reporting window. The new-campaign flag always uses full history. |
| `includeSchedule13G` | `false` | Also report passive 13G stakes. |
| `includeAmendments` | `false` | Also report /A amendments (stake changes, exits). |
| `onlyNewCampaigns` | `false` | Emit only campaign-starting filings (ideal for alerts). |
| `contactEmail` | — | Included in the User-Agent per SEC fair-access policy. Recommended. |

### Output

One dataset item per (filing, target company):

```json
{
  "activist_cik": 1510281,
  "activist_name": "Saba Capital Management, L.P.",
  "form": "SCHEDULE 13D",
  "filing_date": "2026-03-04",
  "acceptance_datetime": "2026-03-04T21:24:15.000Z",
  "accession": "0001062993-26-001289",
  "subject_cik": 748691,
  "subject_name": "KOREA FUND INC",
  "subject_ticker": "KF",
  "is_new_campaign": true,
  "filing_index_url": "https://www.sec.gov/Archives/edgar/data/1510281/000106299326001289/0001062993-26-001289-index.htm"
}
````

### Typical setup: weekly alert

1. Schedule the actor to run weekly (activists file at ~10 campaigns/year — daily is overkill; SEC acceptance after market close means next-day granularity is enough).
2. Set `onlyNewCampaigns: true`.
3. Connect an [Apify integration](https://docs.apify.com/platform/integrations) (email, Slack, webhook) on new dataset items.

The first run parses the activist's full filing history (~1–2 minutes for a prolific filer); subsequent runs reuse a persistent cache and finish in seconds.

### Data source, fair access, and costs

All data comes directly from **SEC EDGAR** (public domain): the submissions API and filing index pages. The actor identifies itself via User-Agent and throttles below SEC's 10 req/s guideline. No third-party data, no scraping of commercial sites.

### Disclaimer

This actor reports public regulatory filings and computed flags. It is **not investment advice**, and the historical statistics quoted above are research results, not a promise of future returns. Do your own research.

# Actor input Schema

## `activistCiks` (type: `array`):

SEC CIK numbers of the activist investors (filers) to monitor. Default: Saba Capital Management (1510281). Find any investor's CIK at https://www.sec.gov/cgi-bin/browse-edgar (company search).

## `lookbackDays` (type: `integer`):

How many days back to report filings for. The new-campaign flag is always computed against the activist's FULL filing history, regardless of this window.

## `includeSchedule13G` (type: `boolean`):

Also report 13G filings (passive ownership above 5%). Off by default: activist campaigns are announced via 13D.

## `includeAmendments` (type: `boolean`):

Also report amended filings (13D/A, 13G/A) — useful for tracking stake increases/exits in ongoing campaigns.

## `onlyNewCampaigns` (type: `boolean`):

Output only filings that start a brand-new campaign (first-ever 13D by this activist on this target). Ideal for alerting.

## `contactEmail` (type: `string`):

SEC's fair-access policy asks automated clients to identify themselves with contact info in the User-Agent header. Strongly recommended.

## Actor input object example

```json
{
  "activistCiks": [
    "1510281"
  ],
  "lookbackDays": 45,
  "includeSchedule13G": false,
  "includeAmendments": false,
  "onlyNewCampaigns": false,
  "contactEmail": ""
}
```

# Actor output Schema

## `filings` (type: `string`):

All filings found in the lookback window, newest first.

## `newCampaigns` (type: `string`):

Only the filings that start a new campaign — the actionable alerts.
