PickStock checkpoints
(items to confirm, not recommendations)
- Check semiconductor and IT sector volume and foreign net buy/sell flows immediately after the morning open.
- Observe whether NVIDIA headlines translate into domestic stock gains and how quickly flows propagate across the sector.
- Check intra-sector temperature differences: is the rise concentrated in large caps or spreading to small caps and equipment names.
- Monitor Bitcoin ETF net outflows and movements in crypto-related stocks, including any related news.
- Pre-check any company or macro events due today (disclosures, earnings, indicators).
Today's trading will hinge on whether external AI semiconductor tailwinds translate into broad buying in Korea or remain localized to certain names and subsectors. For deeper chart and flow analysis, see 차트 기술분석.
