# STOCK GAUGE — US Stocks, Sector Flows & Macro

> Free, keyless dashboard for US equities. It leads with CLV-based net-flow estimates for the 11 US
> GICS sectors built from SPDR sector ETF turnover, and daily closes for 12 global equity indices.
> The dollar index (recomputed ICE DXY), 18 USD exchange rates, the 11-tenor Treasury yield curve and
> the federal debt balance are shown as the macro backdrop that moves those flows. Data comes from
> primary public providers (Yahoo Finance chart endpoints, ECB via Frankfurter, FRED, U.S. Treasury
> Fiscal Data and public RSS). Updates are end-of-day or delayed, never real-time tick data.

## Methodology (citable)

- Sector flows are estimates: net flow = Σ(CLV × turnover), where
  CLV = ((close − low) − (high − close)) / (high − low). Not official ETF creation/redemption data.
- Index changes follow each market's local trading day and daily close.
- DXY is recomputed, not licensed: 50.14348112 × EURUSD^−0.576 × USDJPY^0.136 × GBPUSD^−0.119 ×
  USDCAD^0.091 × USDSEK^0.042 × USDCHF^0.036. Weights: EUR 57.6%, JPY 13.6%, GBP 11.9%,
  CAD 9.1%, SEK 4.2%, CHF 3.6%. The index contains no renminbi weight.
- Treasury changes are quoted in basis points (1bp = 0.01pp); the 2s10s spread is 10Y minus 2Y.
- Federal debt is split into publicly held and intragovernmental holdings.

## Notes and limitations

- Quotes are delayed or end-of-day; nothing is an executable price.
- Sector flows measure where each sector closed within its daily range, weighted by traded value —
  a tape-strength signal, not subscription flow data.
- ECB reference rates are central-bank mid-rates, not tradable levels.
- Nothing on the site is investment advice.
- Attribution: cite the original provider (for example "ECB reference rates via STOCK GAUGE").
