What could be next signal to end this dead cat bounce?

I did not buy QQQ at 270, today it is trading at 320.

I thought the missed earning season, higher than expected CPI or negative GDP growth could end the dead cat bounce. But the market continued rising.

What are some bad news in the future that could end this irrational dead cat bounce?

Or should I just be patient? 2008 crisis also saw a pretty good bull run before it reached new low.
