One of my favorite China-based stocks, JA Solar Holdings (JASO), just reported very strong earnings. The company makes solar cells for photovoltaic modules and conversion systems.

For 2007, JASO earned 40 cents a share, which was a huge increase over the 15 cents a share it made in 2006. Sales rose from $95.5 million to $369.3 million.

But the best part of the report is that JASO said it expects revenues this year to be between $990 million and $1.10 billion. The Street was expecting $779.2 million.

In my Global Growth service, I currently rate JA Solar a "strong buy" up to $13.62 a share.
