China's A-Share Three Major Indices Open Higher Collectively
nashnova research
All three major A-share indices gapped up on September 18, with the ChiNext leading at +1.61% — well above the main board, signaling capital tilted toward growth names right at the open.
How much did each index gain at the open?
The Shanghai Composite opened up 0.42%, the Shenzhen Component 1.15%, and the ChiNext 1.61%.
Gains widened from large-caps to small-caps. This means → opening capital favored mid- and small-cap growth stocks over blue chips.
Why is ChiNext showing more spring?
ChiNext's gain was nearly four times the Shanghai Composite's — the gap appeared instantly at the bell.
In plain terms = ChiNext is heavy on tech, biotech, and new-energy growth names; investors paying up for these stocks signals rising risk appetite.
What does this mean for everyday investors?
A gap-up is only the opening signal — whether volume follows through determines if the move holds.
When ChiNext leads on elasticity, short-term sentiment tends to be optimistic, but volatility cuts both ways. This means → before chasing the rally, watch whether turnover expands in tandem.
