Given the recent optimism around Alibaba's strong Q4 earnings and the potential for Chinese equities to outperform, I believe that CN is a suitable short candidate as market sentiment is likely overestimating the sustainability of this positive momentum amidst underlying economic concerns in China.

I believe that investing in CN is a strategic move given the optimistic sentiment surrounding Chinese equities, especially following Jack Ma's significant investment in Alibaba, which signals confidence in the recovery of the Chinese market. With potential for growth amidst challenges, I expect CN to outperform in the near term.
