The strongest sector

Whenever I am busy during the day, the A-share market suddenly surges. Today, while having lunch with a friend, I glanced at my phone and found that it had suddenly spiked?!
I don't know if during this correction for over a week, everyone took the opportunity to collect chips. For those who opened positions during this time, I reckon they have completely made up for all the paper losses today with just one move.
Today should be the first day for 500 billion yuan mutual exchange convenience to start establishing positions. With so many pullbacks before, it is also to create opening space for them to enter. Normally, they would prioritize buying their own stocks, I guess what they will buy the most is likely a few ETFs:sse science and technology innovation board 50 index ETF, yifangda gem ETF, and chip ETF.
This morning, a classmate chatted with me. He bought a lot in the US stocks. $Direxion Daily FTSE China Bull 3X Shares ETF (YINN.US)$ and $Direxion Daily CSI China Internet Index Bull 2x Shares ETF (CWEB.US)$ Due to the relationship of three times and two times, the recent downturn has been quite severe, a bit worried. I explained to him the candlestick charts of several sectors in the A-share market, especially the candlestick chart of sse science and technology innovation board 50 index: adjusted for a full week, but everyone who bought in before National Day did not get trapped, indicating extremely strong support. Sure enough, the best performance this afternoon is from the sse science and technology innovation board 50 index, very close to the previous high.
I believe in this round of market trends, the strongest one to watch is the sse science and technology innovation board 50 index; within the sse science and technology innovation board 50 index, the strongest would be in the chip sector.
