This linked article is in Chinese:
It focuses on East Bay areas with good school districts like Fremont and San Ramon. It claims prices in those areas have come down 1-5% compared to June. I don’t know if that’s seasonal pattern or not. So draw your own conclusion…
I put the article thru Google translate, but the title comes out exactly opposite to the original! 
The English translation says price “surge” in July. Just the opposite…
“School district room” 学区房 means houses with good school districts.
