Korean Stock Market Scraper - KOSPI & KOSDAQ

Every listed Korean company, with the numbers that matter, in one table. Price, market cap, PER, ROE, foreign ownership and volume for KOSPI and KOSDAQ - timestamped so repeat runs build a time series.

Korean market data is usually locked behind paid terminals or Korean-only portals. This turns it into a spreadsheet in one run.

How to use it

1. Pick markets: KOSPI (main board), KOSDAQ (growth board), or both
2. Set max companies per market - results are ordered by market cap, so 200 gives you the 200 largest
3. Run it, or schedule it daily to build history

Notes

• Market cap is published in 100M KRW units and listed shares in thousands - the actor returns them exactly as published rather than silently rescaling
• PER and ROE are empty for companies where the source reports N/A (preferred shares, loss-making companies) - that is real data, not a parsing gap
• Company names come back in Korean, as listed. Tickers are the standard 6-digit Korean codes

Pairs with

Korean Tech Job Postings Scraper, Korean Job Postings Scraper (Saramin), Naver Map Scraper, Naver Place Detail & Menu Scraper, Korean Price Comparison Scraper - the same Korea data toolkit. Hiring velocity plus market data is a strong combined signal.

FAQ

Is this real-time? It is a snapshot of the published quote board at run time, not a streaming tick feed. For daily or intraday snapshots, use Apify Schedules.

Do I need an account anywhere? No. Public market pages only.

Can I get the full market? Yes - raise the limit and the actor pages through the whole board.

Is this legal? The actor collects publicly published market information at a polite request rate. It is not investment advice. You are responsible for complying with applicable laws and the source site's terms in your use of the data.
