KOSPI index performance
The Kobeissi Letter's line chart drew 293.3K views on X: 1.3x its typical post and #13 of 48 The Kobeissi Letter charts we track by views. Read Oct 14, 2026.
BREAKING: South Korea's stock market is officially down more than -15% over the last 5 days.
Why it spread
The post spread because it hit a hot topic that week with an independent author's voice, reaching 117,525 views, 1,316 likes, 139 reposts, 40 quotes, and 71 saves, with a quote rate above average and source reach in the top quarter.
What worked
- A breaking headline about a sharp five day decline in South Korea's stock market gave the audience an urgent, easy to grasp story.
- The post paired the foreign market drop with Nasdaq 100 futures down 1% overnight, tying a distant event to a market the audience already watches.
- The account posted as an independent author on a hot topic that week, which helped the post travel through quotes and reposts rather than relying on a brand.
What to borrow
We could take a hot market move, state the size and time window plainly in the headline, then connect it to a second market our audience cares about, using our own line chart of the same window.
Careful
Do not copy the low design polishceiling or the missing source line, and do not read the view and like counts as proof that the chart itself was strong, since the hot topic and independent author are listed as the main reasons.
