Fund	First disclosed	Held	Entry price	Latest close	Return on entry
AQR Capital Management	Q2 2026(8Q snapshot)	1Q	$20	$20	-1%

“Return on entry” is the price-only move from the fund's first disclosure to today — it ignores any adds, trims, or dividends. A fund that built its position over multiple quarters has a true cost basis somewhere between entry price and latest close; this figure is the upper bound.

Insider activity

Form 4 — officers, directors, 10%+ owners

Filed within two business days of each transaction by anyone with material insider status at CALAMOS STRATEGIC TOTAL RETURN FUND. Pair with the holders table above as a sanity check: heavy insider buying alongside marquee-fund accumulation is the strongest accumulation signal; heavy insider selling alongside fund exits is the strongest distribution signal.

Fundamentals

XBRL · CALAMOS STRATEGIC TOTAL RETURN FUND

Not enough XBRL history to plot. CALAMOS STRATEGIC TOTAL RETURN FUNDhasn't tagged revenue, net income, EPS, or operating cash flow in the SEC us-gaap taxonomy with at least two fiscal-year periods — typical for SPACs / trust vehicles, pre-revenue biotechs, recent IPOs, and foreign filers reporting under IFRS.

Caveats

Covers only the 27 marquee funds tracked here, not the full institutional universe. A “0 holders” reading does not mean unowned.
Heavy funds (Renaissance Technologies, Citadel Advisors, Soros Fund Management, Two Sigma Investments, D.E. Shaw, AQR Capital Management, Millennium Management, Point72 Asset Management) use 8-quarter snapshots, so their pre-2024 history is missing.
“Current” reflects each fund's most recent 13F — filings lag the actual trade by up to 45 days; positions shown may have changed since.
Cost = price at the entry filing date. Re-entered positions show the most recent open lot.
Options, ADRs, and unmapped CUSIPs are excluded from the follower-backtest pipeline that produces these snapshots, so certain holding types won't appear here.
