Note: Indexes fell sharply, yet capital concentrated in commodities (silver), semiconductor materials/equipment, and traditional defensive insurance names. This shows flows rotating into selected sectors despite broad weakness.
Bottom 3 Weak Themes Today
| Rank | Theme | Avg Move | Up/Down | Representative Laggard |
|---|---|---|---|---|
| 1 | SaaS Software | -6.01% | 0/13 | Banzai International, Inc. (PARA) -14.71% |

| 3 | Cybersecurity | -4.38% | 0/9 | Cloudflare (NET) -7.20% |
Note: SaaS and cybersecurity saw broad selling, while LiDAR losses were amplified by steep declines in specific names. The size of the drops merits attention.
How to View the Next Trading Day
- Both markets plunged (KOSPI -1.55%, KOSDAQ -3.52%), so check whether this reflects a macro shock. The strength of any next-day rebound will be a key inflection for trend assessment.
- Bottom 3 themes average -5.39%, indicating concentrated selling in weak areas. Short-term bounce is possible after large declines, but do not assume a trend reversal solely from one session.
Avoid making trading decisions based on a single-day signal. Use trends over 5 trading days or more together with macro changes for judgment.
