MarketGrep: Liquidity & Stocks

MarketGrep: A daily clipping of US/global financial markets — dollar liquidity, stocks, 13F, Risk Turbulence and sentiment, in one app.

MarketGrep is a market environment dashboard for self-directed investors. One percentile reading tells you where macro liquidity sits today. Ten purpose-built surfaces tell you what's moving and why.

WHAT IT DOES

• Liquidity Regime — The Dollar Liquidity Index (DLI), a composite of 12 macro indicators (Fed balance sheet, TGA, ON-RRP, SOFR spreads, HY credit spreads, VIX, Dollar Index, and more), distilled into one percentile and four regimes: Abundant, Supportive, Restrictive, or Tight. Band transitions flag the moment they happen, with a 10-year regime-colored history chart for the long view.

• Liquidity Signal Field — Policy, Funding, Credit, and Risk visualized as a live macro heat map so you can read tightening pressure before it shows up in asset prices.

• Risk Radar — A multivariate turbulence index (Mahalanobis distance across cross-asset returns) that catches regime shifts before they reach headline indices, with a Danger-Zone divergence alert when equity returns decouple from the broader risk signal.

• US, Global, and Commodities Markets — Exposure scoring, S&P 500 breadth, 52-week proximity, and sortable ticker tables across benchmarks, rates, commodities, FX, crypto, ADRs, and Treasury yields with curve chips. Touch any chart to scrub time × value with a velocity-tuned haptic.

• Most Traded — Top 50 by dollar volume, refreshed continuously. The board readers actually open at the bell.

• Sentiment Briefings — A twice-daily automated analysis of public discussion on high-quality popular investor communities (e.g. WSB), published before the open and after the close. Each report carries a community-wide mood score, the most-mentioned tickers, and verbatim quotes representing the day's themes. Quotes reflect the community, not MarketGrep.

• 13F Research — A curated universe of institutional managers (Berkshire, Tiger Global, Pershing Square, Baillie Gifford, and more) with per-quarter editorial briefs: hand-written one-liner + paragraph summary, AUM trajectory across quarters, top 10 holdings, new positions, largest adds, and largest reduces. Quarterly notes in both English and Chinese.

• Search & Watchlist — Search every global-listed ticker via the open universe, plus the 13F fund-manager catalog and the app's own indicators. Tap any holding to drill into ticker detail. Build a Watchlist with confirm-before-commit add.

• Editorial Share Cards — One-tap long-image share for any ticker or 13F manager. Cream in Light, warm charcoal in Dark, brass hairlines and the official MarketGrep mark.

• Home-Screen Widgets — Smart-Stack tiles for Liquidity regime, Sentiment mood, and Most-Traded leaders.

• Methodology Transparency — Every data product has a dedicated methodology page in Settings, explaining how the score is computed, what the signal reads as, and what its limits are.

• Editorial Design — Newsprint × terminal aesthetic. Serif hero numbers, monospaced data, brass editorial accents. Hand-tuned for both light and dark mode, calm enough for repeated reading during the trading day. Full English and Simplified Chinese, with curated company-name translations so familiar names read naturally in both.
