[Pre-market Analysis for August 20] The Nasdaq dipped and recovered, but semiconductors remain dormant; is this rebound genuine or fake?

The Nasdaq dipped intraday yesterday before recovering, looking somewhat promising. But on closer inspection—The rebound was driven mainly by large-cap tech stocks, while semiconductors remain weak.So this phase looks more likea post-decline repair,and cannot yet be considered a full stabilization. Both the S&P and Dow Jones show purple bands with blue candlesticks; we need to see the disappearance of bearish signals and a confirmed bullish engulfment to verify stabilization. The Dow Jones still shows the first red histogram bar in the trend wave. Many individual stocks are showing slight signs of turning positive. If indices continue to rebound today, many stocks may present buying opportunities as they turn positive.However, for now, the operational strategy is to wait for the right price level plus confirmation of stabilization, rather than chasing the rebound.
