The index is free float market cap weighted and the weight of each stock is capped at 10%. In addition, the total weight of the top 5 constituents should not exceed 40%.The data cut-off for the March review ends on 31 January. The results of the review will be announced towards the end of February and the review will be effective after the close of trading on 12 March.Having gone through over 97% of the review period, we see 13 stocks eligible for index inclusion and 16 stocks in the deletion zone. With only 5 changes permitted in a single review, that is what we will have to settle for. What that also means is that there will be more changes at the June review.For the March review, we see <a href="https://www.smartkarma.com/entities/cambricon-technologies-corp" target="_blank" data-smartkarma-citation="entities:31068:1" rel="noopener">Cambricon Technologies Corp (688256 CH)</a>, <a href="https://www.smartkarma.com/entities/qi-an-xin-technology-group-a" target="_blank" data-smartkarma-citation="entities:31069:1" rel="noopener">Qi An Xin Technology Group (688561 CH)</a>, <a href="https://www.smartkarma.com/entities/shanghai-junshi-bioscience-a" target="_blank" data-smartkarma-citation="entities:31070:1" rel="noopener">Shanghai Junshi Bioscience (688180 CH)</a>, <a href="https://www.smartkarma.com/entities/trina-solar-co-ltd" target="_blank" data-smartkarma-citation="entities:30404:1" rel="noopener">Trina Solar Co Ltd (688599 CH)</a> and <a href="https://www.smartkarma.com/entities/farasis-energy-gan-zhou-co-a" target="_blank" data-smartkarma-citation="entities:28385:1" rel="noopener">Farasis Energy Gan Zhou (688567 CH)</a> being included in the index.<div>
