ATHM and BITA are roughly the same size in terms of revenue. both names are worth watching as the concept of marketing vehicles online is still a fairly new concept in China but it's catching on quickly. BITA has made a huge move this summer (+140% since mid-April). ATHM has mostly been trading sideways the past few months but is starting to get picked up as a lesser known play on BITA.
The ironic thing is that ATHM reported very strong results last week but the stock did not react too much. It wasn't until the better known BITA reported very strong Q2 results Monday in the pre-market that ATHM is starting to get picked up as a secondary play. BITA jumped 10% yesterday and another 5% today on some positive sell side analyst comments from OpCo (firm raised its target on BITA to $78 from $45).
