MarketGrep shows what a broker app leaves out: where Fed liquidity sits, what WallStreetBets is talking about, what 13F managers hold, how the S&P 500 is valued against its own five-year range, and how turbulent cross-asset returns are. English and Chinese; phone, tablet and foldable. No account, no ads, no trading.
LIQUIDITY
The Dollar Liquidity Index from dollarliquidity.com condenses the Fed balance sheet, TGA, reverse repo (ON RRP), bank reserves, funding and credit spreads, VIX, real yields and the dollar index into one composite score, a five-year percentile and a regime: easing, neutral or tightening, with ten years of history. Plus net liquidity, M2, the offshore dollar, and a fiscal section: national debt, budget balance, interest payments, debt to GDP.
US, GLOBAL, COMMODITIES
The US tab reads S&P 500 breadth over 20, 50 and 200 days, a VIX, dispersion, correlation and MOVE strip, the day's volume leaders, and sortable index, sector, industry and managed-ETF tables. Global covers developed and emerging markets through headline ETFs. Commodities puts 2- and 10-year Treasury yields beside gold, silver, copper, oil and the bitcoin and ether ETFs. Most Traded lists the 50 most active US names.
SENTIMENT
Each US trading day an automated pipeline reads thousands of public WallStreetBets posts and comments and reports a mood score, the most-mentioned tickers and a short report with quotes, in English and Chinese. Two optional notifications a day, before the US open and after the close, carry the mood and leading tickers. Quotes reflect the community, not MarketGrep.
13F HOLDINGS
Quarterly filings from a curated set of managers, including Warren Buffett's Berkshire Hathaway, Bill Ackman's Pershing Square, Stan Druckenmiller, Tiger Global, Li Lu, Duan Yongping, Hillhouse and Norges Bank. A manager page shows reported value, holdings count, the weight of the five largest positions, new positions, largest adds and reduces, exits, the trajectory across quarters and the SEC filing link.
VALUATION
Forward P/E, earnings yield and five-year percentile for the S&P 500, Nasdaq 100, semiconductors and the information technology sector, shown as a position in its own range, not a cheap-or-expensive call.
RISK RADAR
A turbulence index (the Mahalanobis distance of cross-asset returns) against warn and extreme thresholds, with a Danger Zone marker when turbulence is elevated while the S&P 500 holds above its 50-day average and VIX is calm.
TICKERS, SEARCH, WATCHLIST
Every ticker page has a chart from one day to all history with a drag read-out, key figures, an ETF's ten largest holdings and a profile. Search finds US-listed tickers, 13F managers, liquidity indicators and the app's own pages in English or Chinese: try "AAPL", "苹果" or "Ackman". Star any ticker to build a watchlist that also lives on a widget. Share tickers, managers and the risk regime as image cards.
WIDGETS, TABS, LAYOUT
Four home-screen widgets (liquidity regime, market sentiment, volume leaders, watchlist) refresh in the background. Tabs can be reordered and switched on or off. Up is blue, down is red, and every change carries a caret, so direction never depends on colour alone. On tablets and unfolded foldables the tab bar becomes a side rail and lists open detail in a second pane.
PRIVACY AND COST
No account, no sign-in, no analytics or advertising SDK. Your watchlist, tab order and settings stay on your device; the app asks for no location or contacts permission and only fetches market data from MarketGrep's servers and dollarliquidity.com. No subscription, no paywall; an optional one-time tip supports development.
NOT INVESTMENT ADVICE
What you see here is not investment advice, a recommendation, an offer or a solicitation. Figures may be delayed, incomplete or wrong; past readings do not predict future results.
