$NVIDIA(NVDA.US)

NVIDIA has regained its position as the world's most valuable company, with its impressive earnings report alleviating many market concerns, and there is still room for further growth.

However, whether the worst is over depends on several factors:

First, can the high valuation sustain future growth?

Second, will there be breakthroughs in the restricted Chinese market?

But in the long term, industry competition and policy uncertainties still need attention.
