Zero Sum Wheel
Explore Taiwan's market turnover, sector by sector
See how trading activity is spread across Taiwan's stock market. Explore industries, replay daily snapshots, and compare turnover shares with stock-price changes over 8, 20 or 60 trading days. Free to use, with English and Traditional Chinese. Covers TWD-denominated securities on TWSE and TPEx.
I built Zero Sum Wheel to make Taiwan's daily market data easier to explore. Start with the wheel to see how trading activity is split across industries. Pick an 8-, 20- or 60-trading-day window, then open an industry or a stock's price chart to look closer.
The wheel shows each group's share of trading value. The animated links illustrate changes in that share; they aren't a record of money moving from one industry to another.
The site is free, opens in English, and has a Traditional Chinese switch. It covers TWD-denominated securities on Taiwan's TWSE and TPEx markets. The data is updated after the trading day, with the date shown on the page.
There's also a separate fixed-method research panel. It includes dates, sample sizes and negative results so the numbers have context.
I used GPT-6 Astra in Codex to build and test the app. I'd love to hear whether the wheel makes sense on your first visit, and which comparisons you'd find useful.
