CEF Discount & NAV Monitor

Daily premium/discount snapshot for US closed-end funds (CEFs) — the only CEF data source on Apify. For each fund: market price, NAV, current discount, trailing z-score and percentile, plus flags for unusually wide or narrow discounts.

Why discounts matter

A closed-end fund trades at a market price that can differ substantially from the value of its holdings (NAV). Discounts mean-revert: an unusually wide discount (z-score ≤ −2 vs its own trailing year) has historically tended to narrow back. This actor computes exactly that signal — the classic input for CEF mean-reversion strategies, discount screens, and activist-target watchlists.

Pairs naturally with the SEC Activist 13D/13G Monitor: activists target CEFs with persistent wide discounts.

Input

Field	Default	Description
`tickers`	built-in universe	Any US CEF tickers. Empty = ~50 liquid equity/hybrid CEFs (Adams, Gabelli, Eaton Vance, BlackRock, Cohen & Steers...).
`zScoreWindowSessions`	`252`	Trailing window for z-score/percentile (252 = 1 year).
`historyRange`	`2y`	Daily history downloaded per fund.
`onlySignals`	`false`	Output only funds with z ≤ −2 or z ≥ +2 (alerting mode).
`proxyConfiguration`	Apify proxy	Proxy for data requests.

Output

One item per fund, sorted from the widest discount:

{
  "ticker": "RVT",
  "date": "2026-07-06",
  "price": 18.37,
  "nav": 21.0,
  "discount_pct": -12.52,
  "discount_avg_pct": -9.59,
  "z_score": -1.74,
  "percentile": 5.2,
  "window_sessions": 252,
  "window_min_pct": -13.1,
  "window_max_pct": -5.8,
  "is_unusually_wide": false,
  "is_unusually_narrow": false
}

Funds without a NAV series on the data source (or with under 60 overlapping sessions) are skipped and listed in the log — no silent gaps.

Typical setup

Schedule a daily run after US market close (e.g. 22:30 UTC), with onlySignals: true and an email/Slack/webhook integration — you get pinged only when a discount leaves its normal range.

Data source & disclaimer

Price and NAV series come from publicly available Yahoo Finance endpoints (NAV under the X{TICKER}X symbol convention). Data is end-of-day and provided as-is; verify before trading. This actor is not investment advice — historical mean-reversion of discounts is a research finding, not a guarantee.
