PickStock checkpoints

• Flow persistence: Confirm whether the prior-day surge is short-lived momentum or continues via program and foreign flows at the open, and watch for profit-taking pressure.
• Sector linkages: Check if US IT and semiconductor strength provides further lift to domestic semiconductor and IT names and to KOSDAQ overall.
• Crypto impact: Monitor how ETF inflows affect crypto and blockchain-related stocks.
• Volatility signals: Watch bid-ask spreads and volume in names with large prior-day gains to spot downside risk early.
• Macro variables: Follow Fed-related positioning (the market's prevailing bet against a September rate hike) and any shift in global risk on/off sentiment as drivers of short-term flows.

This morning requires gauging whether yesterday's surge persists at the open or whether profit-taking and sector divergence trigger a pullback. Check the points above at both market and stock levels first. 내 종목 레이더
