Each region uses its own source list and publication cadence.
Why Multi-Language Matters for Alpha
Case study 1: A Chinese regulatory action on Alibaba broke on 财联社 at 22:47 Beijing time. English feeds picked up the Reuters translation at 23:12 Beijing — a 25-minute gap. US pre-market trading started reacting within that window. Case study 2: Nikkei announced a supply chain update on a specific auto OEM at 09:15 Tokyo. English feeds (Reuters, Bloomberg) didn't pick it up until 11:40 Tokyo (2.4 hour gap). Traders watching Japanese regions caught the move early.For names where corporate news breaks in non-English first (most Asian stocks, many European stocks), multi-region monitoring gives genuine lead time.
When to Filter to One Region
Sometimes a single region is optimal:
US-only positions
Trading only S&P 500 names? English region covers 90%+ of material news. Non-English regions mostly re-report English originals. Set region filter to English only to cut noise by 60%.
Region-specific plays
Trading CAC 40, DAX, or Nikkei specifically? Start with the native region first — it will have local analyst depth English feeds miss.
Compliance reasons
If you're a regulated entity constrained to "published" English-language sources, filter accordingly.
When to Go Global
Asian tech / chip stocks
SMIC, TSMC, Samsung, Sony — news breaks in Chinese, Japanese, or Korean first. Translation lag = opportunity loss.
Commodities
Russian energy, Middle East oil, Chinese commodities — native sources move futures before English analysts write reports.
Geopolitical positions
Taiwan, Iran, Ukraine — multi-region coverage captures different perspectives and breaking details.
Crypto
Korean exchange news (Upbit, Bithumb moves) breaks in Korean. Japanese retail flow signals appear in Japanese media. English coverage lags.
How Catalayer Deduplicates
Across 13 regions × 50+ sources, the same story might appear 5-15 times. Our dedup logic:
- Headline fingerprint: Stories with similar normalized headlines (after translation hints) are grouped
- Time-window matching: Stories within 30 minutes of each other are candidates
- Stock symbol overlap: Same tickers mentioned = higher dedup confidence
- Preservation: We keep the first-published version + link to related from other regions
Result: your feed shows the lead story once, with sibling versions collapsed as "5 related coverage" links.
Filtering in Practice
In the [News workspace](/news), the region filter sits at the top. You can:
- Select any combination of the 13
- Save preset filters (e.g., "US + Asia" for US-listed Chinese tech names)
- Toggle regions during specific events (enable Russian only during OPEC+ meetings)
Common Mistake: Always-All-Regions
Users who leave all 13 regions on permanently get 3x the volume with only 15-20% additional material signal. Better pattern:
- Default: English + Chinese (covers 85% of global material news for global stocks)
- Event-specific: Enable additional regions matching the event
- Sector-specific: Auto on specific regions for specific sectors (Japanese for semis, French for luxury, etc.)
Source Priority Within Regions
Within English:
- Speed tier: Investing.com, Seeking Alpha, Reuters, MarketWatch (60s latency)
- Analysis tier: CNBC, Bloomberg, WSJ (slower but deeper)
- Long-tail tier: Motley Fool, MarketBeat, Barron's (more opinion)
Within Chinese:
- Wire tier: 财联社 (fastest), 新浪财经
- Portal tier: 东方财富, 雪球
- State media: 人民网财经 (use for policy signals)
Within Japanese:
- Nikkei leads for corporate news
- Reuters Japan for multinationals
Performance Implications
More regions = more data. Our feed refresh is:
- 50-150 stories/minute across all regions
- Per-region filter reduces your feed to 30-60 stories/minute
If you're running dozens of monitor rules simultaneously, narrower region filter improves alert precision.
FAQ
Q: Are non-English stories auto-translated?A: Headline context is extracted using language-aware tokenization. Full body remains in original language — users can apply one-click translation in the workspace.
Q: Can I set different rules per region?A: Yes. Monitor rules can specify region filters: region:(Chinese OR Japanese) AND (semiconductor OR TSMC).
A: Chinese: 30-60s from publication. Japanese: 60-120s. Most European regions: 60-180s. Russian and Turkish: 120-300s (fewer direct feed partnerships in those markets).
