$微博(WB)$ 去年底就可以可以看做全流通了查了2月17日的 SC 13G/Asina持有近50%的股份是class B 这部分占投票权是class a的三倍 其他一样 Each Class B ordinary share is entitled to three votes per share, whereas each Class A ordinaryshare is entitled to one vote per share.Based on 218,076,207 Class A ordinary shares outstanding as of December 31, 2016 and assuming all Class B ordinary shares held by such reportingperson are converted into the same number of Class A ordinary shares.理论上sina可以卖掉weibo总股本25%的股份 剩下的class B 投票权是3倍 0.25×3/(1+0.25×3+0.75)=0.5 仍然绝对控股 当然前提是sina想套现
