A股三大股指集体高开，沪指涨0.36%，创业板指涨0.9%。盘面上，CPO、光刻机、算力租赁等板块涨 幅居前。 这种情况下，调仓的思路不是刻意回避AI叙事，而是尽量选择ROE底部向上趋势性抬升的品种，从这 个角度来看，适度增加对化工、有色、电新这样沉寂比较久且利润率和行业景气度在历史相对低点的行 业，是更优的选择。 另外，AI叙事只是影响了行情斜率而不是趋势。，如果未来AI叙事出现波动，的确可能会带来这些行 业剧烈的波动，但只要ROE能实现从底部开始向上的持续抬升，这种股价波动都只是短期的(相对于那 些ROE在历史高点的行业而言)，不会威胁到本金安全。 招商证券：有色、钢铁、建材是当前可以考虑布局的顺周期选择 机构看后市 中信证券：适度增加化工、有色、电新的仓位，是更优的选择 10月以来市场波动加大，但择时成功率并不高，背后的原因是增量资金的底层结构在发生变化，稳健绝 对收益型资金持续入市在降低传统激进策略择时的有效性。当前真正重要的变量还是企业出海环境的稳 定性以及AI，涉及到的是中美关系以及AI基础设施的投建进程。当前不仅是TMT板块，连有色、化 工、电新的上涨直接或间接都受到AI叙事的影响，而这些板块占 ...
