句子意思是：在期货中,基差与基差风险是一回事吗?
两者是不同概念
差是指某一特定商品在某一特定时间和地点的现货价格与该商品在期货市场的期货价格之差,即：基差＝现货价格一期货价格.参照物不同,基差结果不同.
在股指期货交易中,由于现货价格与期货价格波动不一致、从而基差波动不确定而导致的风险被称为基差风险.如果基差朝着有利方向变化,则不仅可以取得较好的套期保值效果,而且还可以获得额外的盈利；反之,不仅会影响套保效果,甚至还会蒙受损失.比如,在买入套期保值中,由于在套保结束时要买入现货并卖出期货合约,当基差变弱、即现货价格相对更低而期货价格相对更高时,投资者买低卖高就可能获利.相反,如果此时是卖出套期保值,由于在套保结束时要卖出现货并买入期货合约,因此当基差变弱时,投资者卖低买高则可能亏损.
