"As I mentioned at the beginning of this quarterly letter, we took advantage of the meltdown in technology platforms to initiate new positions in companies in which we had already been shareholders in the past and whose valuation did not, until now, provide a sufficiently high margin of safety.

The company has been the leading Internet search engine in the Asian country for years, which has given it a historically privileged position to monetize, through online advertising, a huge user base. However, the rise of two types of applications has called into question the sustainability of its business model. On the one hand, mobile social apps, such as ByteDance's well-known TikTok, have emerged as a new model of online consumption, generating a new platform through which to monetize Internet users.
