As filed. We do not recategorize line items. Each chart plots one XBRL concept exactly as SPTX tagged it: net income us-gaap:NetIncomeLoss, EPS us-gaap:EarningsPerShareDiluted, period by period; a period the company did not tag on its own is left out, not estimated. A figure that disagrees with the filing is a bug in our extraction, not a policy, and we fix it: report a mismatch.

No tracked institution reported a position in SPTX in the latest 13F round.
Every registered fund files its complete portfolio with the SEC. These weights come from those filings, so each one carries the period it describes. Holdings are quarterly and filed in arrears — the figures below are as of 2026-06-30, not today.
| Fund | Weight | As of |
|---|---|---|
| VTI Vanguard Total Stock Market ETF | <0.01% | 2026-06-30 |
Drawn from 39 large US equity funds we scan, not every fund in existence, so a missing fund means we do not scan it rather than that it holds none. Holdings are joined to tickers by issuer name, which does not resolve every position; what that misses is published.

1 of the 1 checks that ran found nothing new for SPTX. 3 could not run.
Each event check looks back 30 days from the date its own source was stored, read or generated, never from the date this page was built. A check that finds nothing is a measurement of that window, not a forecast, and a check that cannot be dated does not make the claim at all.
From SEC Form 4 and 13F filings. Both are backward-looking disclosures on different reporting clocks, and neither predicts price. Educational information only — not investment advice.
