@michaelsikand·3hBroadcom's networking guide is the real story this week. The whole timeline is finally getting the AI backbone trade.
@daniel_koss·5hA lot of this semis euphoria is the same accounts that were bearish at the lows. I would want to see real follow-through first.
@thevalueist·6hDemand signals here are genuinely strong, not just chatter. Adding on any weakness into the print.
Follow the accounts with a record. Tune out the loud ones.
Quantral grades each voice it tracks, from X accounts to Naver blogs and members of Congress, on whether their past calls played out: how many they made and how many were right. Quantral weighs strong records more, so confident posts from people who keep missing count for little. You’ll find the best records on the leaderboard.

Read what Korean investors and analysts say, in English.
Korean investors write up the stocks they own on Naver blogs, and they cover companies English-language feeds skip. You read each post as a one-line English summary, with the Korean a tap away. On the same page you see Korean broker research from Telegram, also in English. Quantral grades both on whether their past calls played out. Naver posts count toward the score on Korean companies; broker notes sit next to it as context.

More on Congress trades in Quantral
Spot when insiders put their own money in.
When an officer, director or 10% owner buys shares on the open market, you see who bought, their role and the amount, for US and Korean companies. An insider who buys puts their own money into a business they know from the inside, so we show only buys. We don't grade insiders.

Questions, answered
Finance X, Reddit and Substack, Korean investing blogs on Naver, Korean broker research on Telegram, the stock trades members of Congress disclose, and open-market buys by company insiders, from SEC Form 4 filings in the US and DART in Korea.
Every source except company insiders: authors on X, Reddit and Substack, Naver blogs, Telegram broker research channels, and members of Congress. Quantral grades each voice on whether their past directional calls played out, and the best records count for more in the score. Telegram analysts get a track record but stay off the leaderboard, and broker notes show as context without moving the score. For Congress, a disclosed purchase counts as a bullish call and a sale as a bearish call, and members appear on the same leaderboard as every other voice. Company insiders are not graded.
Quantral reads crowd posts and broker research notes as they go up, and picks up Congress trades and insider purchases as they're filed. Members of Congress have up to 45 days to disclose a trade, so those usually show up days to weeks after the trade itself.
Yes. Every Naver blog post comes with an English summary, and you read broker research notes in English. On a Naver post, tap See original to read the Korean text.
No. Every number Quantral shows describes the sources we track, not all of social media or every investor. We choose sources where stocks get discussed in depth.
No. Quantral surfaces signals and context from public sources to help you do your own research. Nothing here is financial advice or a recommendation to buy or sell.
