Wind數(shu)據顯示，9月以來，A股(gu)(gu)(gu)共(gong)有(you)190家上市(shi)公(gong)(gong)司(si)的(de)338位重(zhong)(zhong)(zhong)(zhong)要(yao)股(gu)(gu)(gu)東(dong)(dong)發(fa)(fa)布(bu)計(ji)劃減(jian)持(chi)(chi)公(gong)(gong)告，共(gong)涉及28.06億股(gu)(gu)(gu)。償還(huan)債務(wu)減(jian)少資產負債率、個人資金(jin)需求(qiu)、個人財務(wu)安排、持(chi)(chi)股(gu)(gu)(gu)企(qi)業經營(ying)業務(wu)發(fa)(fa)展(zhan)需要(yao)等，是上市(shi)公(gong)(gong)司(si)重(zhong)(zhong)(zhong)(zhong)要(yao)股(gu)(gu)(gu)東(dong)(dong)減(jian)持(chi)(chi)的(de)主(zhu)要(yao)原(yuan)因(yin)。同時，也有(you)不少上市(shi)公(gong)(gong)司(si)重(zhong)(zhong)(zhong)(zhong)要(yao)股(gu)(gu)(gu)東(dong)(dong)為(wei)了維護股(gu)(gu)(gu)價穩(wen)定，增強(qiang)投資者信(xin)心(xin)，終(zhong)止了此(ci)前(qian)的(de)減(jian)持(chi)(chi)計(ji)劃；更有(you)上市(shi)公(gong)(gong)司(si)重(zhong)(zhong)(zhong)(zhong)要(yao)股(gu)(gu)(gu)東(dong)(dong)承諾不減(jian)持(chi)(chi)。此(ci)外，為(wei)了給(gei)予(yu)投資者信(xin)心(xin)，近期發(fa)(fa)布(bu)重(zhong)(zhong)(zhong)(zhong)要(yao)股(gu)(gu)(gu)東(dong)(dong)增持(chi)(chi)、回購股(gu)(gu)(gu)份方案的(de)上市(shi)公(gong)(gong)司(si)數(shu)量(liang)也較多。

　　解禁規模增加

　　從(cong)涉及重要股東減持(chi)的(de)上(shang)市公司所在行(xing)業(ye)(ye)看，計算機(ji)、通信(xin)和其他電子設備制(zhi)造業(ye)(ye)，化學原料和化學制(zhi)品制(zhi)造業(ye)(ye)，專用設備制(zhi)造業(ye)(ye)，電氣機(ji)械和器材制(zhi)造業(ye)(ye)，軟件和信(xin)息技術服(fu)務業(ye)(ye)等行(xing)業(ye)(ye)上(shang)市公司涉及重要股東減持(chi)的(de)數量較多。

　　部(bu)分上市公(gong)司(si)(si)(si)重要股(gu)(gu)東(dong)(dong)擬減持(chi)比例(li)(li)較高。以三五互(hu)聯為例(li)(li)，公(gong)司(si)(si)(si)9月(yue)15日(ri)晚間公(gong)告(gao)，近日(ri)接到(dao)大股(gu)(gu)東(dong)(dong)龔(gong)(gong)少暉(hui)擬減持(chi)股(gu)(gu)份(fen)的通知，截至(zhi)本公(gong)告(gao)披露日(ri)，龔(gong)(gong)少暉(hui)持(chi)有(you)公(gong)司(si)(si)(si)股(gu)(gu)份(fen)1.35億(yi)股(gu)(gu)，占公(gong)司(si)(si)(si)總股(gu)(gu)本的36.88%。龔(gong)(gong)少暉(hui)計劃自(zi)本公(gong)告(gao)披露之日(ri)起15個交易日(ri)后的未來(lai)6個月(yue)內減持(chi)不超(chao)過2194.19萬(wan)股(gu)(gu)股(gu)(gu)份(fen)，占公(gong)司(si)(si)(si)總股(gu)(gu)本的6%。

　　Wind數據(ju)顯示，9月21日至25日，一(yi)(yi)共有42家(jia)公(gong)司(si)的73.18億(yi)股限售股解(jie)(jie)禁，解(jie)(jie)禁市值(zhi)為956.15億(yi)元。其(qi)中，21日是解(jie)(jie)禁高峰，解(jie)(jie)禁規模(mo)(mo)達503.35億(yi)元，占(zhan)全周比(bi)例(li)的52.64%。業內人士指(zhi)出，解(jie)(jie)禁規模(mo)(mo)增加，使(shi)得上(shang)市公(gong)司(si)短期內發布重要股東減持計(ji)劃的可能性進一(yi)(yi)步加大。

　　承諾不減持

　　值(zhi)得注(zhu)意(yi)的是(shi)，與上(shang)述發(fa)布重要股(gu)(gu)東減持計劃的上(shang)市公司不同，很多上(shang)市公司為了提(ti)振(zhen)投資(zi)者信心(xin)，發(fa)布重要股(gu)(gu)東不減持公告。

　　部(bu)分公(gong)(gong)司(si)(si)承(cheng)諾期較長。以(yi)大連圣亞為例，公(gong)(gong)司(si)(si)近日公(gong)(gong)告，公(gong)(gong)司(si)(si)董事(shi)會(hui)于9月17日收到股(gu)(gu)(gu)(gu)東磐(pan)京(jing)股(gu)(gu)(gu)(gu)權投(tou)資基(ji)金(jin)管理（上海）有(you)限(xian)公(gong)(gong)司(si)(si)的《承(cheng)諾函》。磐(pan)京(jing)基(ji)金(jin)承(cheng)諾自2020年9月17日至2030年9月16日，不以(yi)任何方式(shi)主動(dong)減持(chi)其所(suo)持(chi)有(you)的2410.14萬股(gu)(gu)(gu)(gu)公(gong)(gong)司(si)(si)股(gu)(gu)(gu)(gu)份(fen)(fen)，包(bao)括(kuo)承(cheng)諾期間因送股(gu)(gu)(gu)(gu)、公(gong)(gong)積金(jin)轉增(zeng)股(gu)(gu)(gu)(gu)本等權益分派產生的新增(zeng)股(gu)(gu)(gu)(gu)份(fen)(fen)。在上述承(cheng)諾期間，如磐(pan)京(jing)基(ji)金(jin)或其一致(zhi)行動(dong)人違反承(cheng)諾，則磐(pan)京(jing)基(ji)金(jin)或其一致(zhi)行動(dong)人減持(chi)公(gong)(gong)司(si)(si)股(gu)(gu)(gu)(gu)份(fen)(fen)所(suo)得收益全部(bu)歸公(gong)(gong)司(si)(si)所(suo)有(you)。

　　針對(dui)不減(jian)持(chi)原(yuan)因，大連圣亞公(gong)(gong)告顯示，磐京基金基于對(dui)公(gong)(gong)司(si)(si)未來(lai)發(fa)展(zhan)前景的(de)(de)(de)信心(xin)和長期投資(zi)價值的(de)(de)(de)認可，支持(chi)公(gong)(gong)司(si)(si)未來(lai)發(fa)展(zhan)戰略，促進(jin)公(gong)(gong)司(si)(si)的(de)(de)(de)長期、持(chi)續、健康發(fa)展(zhan)，進(jin)一步穩定投資(zi)者(zhe)市場預期，維護廣大投資(zi)者(zhe)利益，自愿承(cheng)諾不減(jian)持(chi)。

　　中國證券(quan)報記者(zhe)梳理發現，從(cong)近期(qi)承諾(nuo)不減持的主體看(kan)，控(kong)股股東和高級(ji)管理人員占比(bi)較大(da)，維護公司股價穩定意圖明顯(xian)。

　　以揚(yang)(yang)杰(jie)科技為例，公(gong)(gong)司(si)(si)(si)于(yu)2020年(nian)9月8日(ri)(ri)收到了公(gong)(gong)司(si)(si)(si)控股(gu)(gu)(gu)股(gu)(gu)(gu)東揚(yang)(yang)杰(jie)投資(zi)(zi)出具的(de)《關于(yu)不(bu)減持揚(yang)(yang)杰(jie)科技股(gu)(gu)(gu)份的(de)承諾函》，截(jie)至本公(gong)(gong)告披露(lu)日(ri)(ri)，控股(gu)(gu)(gu)股(gu)(gu)(gu)東揚(yang)(yang)杰(jie)投資(zi)(zi)持有公(gong)(gong)司(si)(si)(si)股(gu)(gu)(gu)份1.96億股(gu)(gu)(gu)，占公(gong)(gong)司(si)(si)(si)總股(gu)(gu)(gu)本的(de)41.55%。基(ji)于(yu)對公(gong)(gong)司(si)(si)(si)價(jia)值的(de)認可(ke)及(ji)對公(gong)(gong)司(si)(si)(si)未來發(fa)展(zhan)前景的(de)信心，為支持公(gong)(gong)司(si)(si)(si)持續(xu)、穩(wen)定、健康發(fa)展(zhan)，切實(shi)維護全體股(gu)(gu)(gu)東利益(yi)，揚(yang)(yang)杰(jie)投資(zi)(zi)承諾自(zi)本公(gong)(gong)告披露(lu)之日(ri)(ri)起12個月內不(bu)主(zhu)動減持前述股(gu)(gu)(gu)份。

　　終止減持計劃

　　上市公司重要股東近日終止減持計(ji)劃的數量較多(duo)。終止的原因主要和恢復投資(zi)者(zhe)信心、維護股價(jia)穩定(ding)、短線操作失誤提(ti)前終止、減持期(qi)臨近屆滿(man)、個(ge)人(ren)資(zi)金(jin)通(tong)過(guo)其他渠(qu)道解決等因素(su)有(you)關(guan)。

　　能科股(gu)份近(jin)日公(gong)(gong)(gong)告(gao)，9月3日，公(gong)(gong)(gong)司(si)(si)收到實際(ji)控制人之一、副董事(shi)長、總(zong)(zong)(zong)裁趙(zhao)嵐(lan)出具的(de)《關于提(ti)前(qian)終(zhong)止(zhi)股(gu)份減持計(ji)劃(hua)的(de)告(gao)知函》。鑒于個(ge)人資金(jin)需求(qiu)已通(tong)過其(qi)他渠道(dao)解決，結合對(dui)(dui)公(gong)(gong)(gong)司(si)(si)未(wei)(wei)來發展的(de)信(xin)心(xin)以及對(dui)(dui)公(gong)(gong)(gong)司(si)(si)價(jia)值的(de)認同，經綜合考慮(lv)，趙(zhao)嵐(lan)決定提(ti)前(qian)終(zhong)止(zhi)本次股(gu)份減持計(ji)劃(hua)，且趙(zhao)嵐(lan)及其(qi)一致行動人祖軍、于勝濤承諾在未(wei)(wei)來六個(ge)月內無(wu)減持計(ji)劃(hua)。截(jie)至本公(gong)(gong)(gong)告(gao)披露日，趙(zhao)嵐(lan)通(tong)過集中(zhong)競(jing)價(jia)、大(da)宗交易累計(ji)減持公(gong)(gong)(gong)司(si)(si)股(gu)份426.4萬股(gu)，占當(dang)前(qian)總(zong)(zong)(zong)股(gu)本的(de)3.06%。此(ci)前(qian)，趙(zhao)嵐(lan)計(ji)劃(hua)通(tong)過集中(zhong)競(jing)價(jia)、大(da)宗交易方式減持所持有的(de)公(gong)(gong)(gong)司(si)(si)股(gu)份，合計(ji)減持數量不(bu)超(chao)過583.2萬股(gu)，不(bu)超(chao)過公(gong)(gong)(gong)司(si)(si)總(zong)(zong)(zong)股(gu)本的(de)4.19%。

　　除終止減持動作(zuo)外，為了給予投資(zi)者信心(xin)，發布重要股(gu)東增持、回(hui)購股(gu)份方(fang)案的上市公(gong)司數量較多。
