The tech stocks will drop because I bought them yesterday

The stock price dips after buying the dip and goes up after selling. This is a kind of trading law so it is natural to see NVDA drop today. S&P futures are going down by 0.5%.

If the CPI is higher than expected, Federal Reserve will discuss extra 75 basis point rate hike. But the prices of used cars and houses (in some areas) have fallen recently and the WTI oil price was severely dropping in summer, which means it is possible that the inflation has peaked temporarily.
