Last week's acquisition of Chinese online retailer Joyo by Amazon.com appears to have touched off a bit of speculative fever in Chinese Internet stocks.

SINA soared 16% Wednesday on rumors that Yahoo could make a play for the company. The rumors have surfaced before, but Amazon's recent acquisition appears to have traders listening more closely.

With Amazon and eBay — with its 2003 acquisition of EachNet — looking more closely at China, it stands to reason that Yahoo might not be far behind. With a market cap of $1.15 billion, though, SINA would not come cheap.

SINA and other Chinese Internet stocks have been hit recently by sanctions from China Mobile, which has been cracking down on wireless messaging violations. NetEase and SOHU rode SINA's coattails to 10% gains each on Wednesday.

The broader market surged as oil prices tumbled and traders shook off weak home sales and a gain in durable orders that was driven mainly by aircraft orders.

Advancers led 23-9 on the NYSE, and 20-9 on the Nasdaq. Upside volume was 75% on the NYSE, and 84% on the Nasdaq. New highs-new lows were 105-16 on the NYSE, and 43-49 on the Nasdaq.

After the close, Opsware beat estimates, and ADC Telecom missed. Apollo reaffirmed guidance, and Cirrus warned.

During the day, ADE soared 21% on its results, and Semtech rose 6% after beating estimates.
