China’s ancient oracle bones reveal earliest written record of meteor shower 3,000 years ago_我的网站

一 |     A股第二大规模宽基指数，A500ETF或将掀起一轮新鏖战。                   市场传言称，“上交所和深交所预计各选1只中证A500ETF纳入期权标的”。

(Photo by Qian Boyu/Xinhua)Chinese archaeologists have pieced together ancient oracle bone fragments to decipher what they say is the earliest written record of a meteor shower, dating back more than 3,000 years and shedding light on astronomical observation in the Shang Dynasty (c.1600BC-1046BC), roughly the Late Bronze Age in the West in which Homer's Odyssey was rooted.
The inscription, found among more than 80,000 fragments, consists of three characters that read "star", "all" and "west," describing a large number of meteors streaking across the night sky and falling westward like rain, Huang Tianshu, a professor at Tsinghua University's Research and Conservation Center for Unearthed Texts, told the Global Times.
"The first character is 'star'… the second means 'all' or 'in batches', depicting meteors falling in large numbers like rain, and the third is 'west,' used as a verb to mean falling westward after crossing the sky," Huang said. "This is important astronomical data recording a meteor shower more than 3,000 years ago."
The team spent years rejoining shattered oracle bones, a process of piecing fragments back together, and only after reassembly did the meaning become clear. 
"Before rejoining, you have no idea what it is saying. Once rejoined, the content becomes largely intact and turns into a very important piece of material for studying history or language," Huang added.

The discovery is part of a decade long effort that has newly rejoined more than 1,200 groups of fragments, with the results published in a major compendium of oracle bone facsimiles. The research was part of a state-backed project on inheritance and studies of ancient Chinese scripts and civilization, CCTV reported.
The first phase of the national project is about to complete, yielding a string of major findings. These findings provide vital new materials for studying early Chinese civilization and demonstrate the significant value of ancient Chinese characters in the development of Chinese and even human civilizations, per CCTV.
。消息一出，立马引发热议。

二 |                    一方面，首批中证A500ETF上市已经超过一年，纳入期权标的也在预期之内；另一方面，当前已上市A500相关ETF超40只，上交所、深交所各占半壁江山，如按传言，单交易所仅有1只纳入，谁能入选？                    有基金公司方面表示，对于纳入期权标的暂无确切消息，但是A500规模之争早已暗潮涌动。

三 |                    最新规模来看，40只中证A500ETF以及增强ETF最新规模为1928.24亿元。

四 |                    其中，200亿以上规模A500ETF已有3只，上交所上市的华泰柏瑞A500ETF自今年内6月底稳居行业第一，最新规模为238.96亿元，国泰中证A500ETF和易方达A500ETF紧随其后，两只ETF均在深交所上市。

五 |                    又“卷”起来了，A500ETF成交额霸屏                    A500ETF持营战再次打响。10月20日，市场冲高回落，缩量上涨，热点轮动没有明显的主线，资金活跃度上，A500ETF一只独秀。截至收盘，全市场股票ETF成交额前十中，A500ETF占据了5个席位。

六 |                    具体来看，华夏A500ETF成交额为50.81亿元，领跑股票ETF成交榜，国泰A500ETF和华泰柏瑞A500ETF成交额均超40亿元，南方A500ETF、易方达A500ETF成交额同样排名靠前。

七 | 40余只中证A500ETF合计成交额超274亿元，上述成交额前五的A500ETF合计成交213亿元，占比近8成。                   场内成交额代表了流动性，尽管成交额高不一定意味着资金流入规模多，资金流入更多体现在份额申购而非二级市场买卖。但是对于非行业主题ETF，且规模不占优势的品种上，多只产品同时成交额放大，背后原因或是做市商交易活跃，是基金公司持营的方式之一。

八 |                              宽基ETF是持久战，这是入场基金公司的共识。                   作为全市场第二大宽基指数，A500ETF的持营战依然是在前半程。

九 | 从规模来看，场内A500相关ETF规模为1928亿元，整体较最高峰2700亿元缩水明显，产品规模差距拉大，已有12只ETF规模不足2亿元。                   但是对于头部ETF基金公司而言，A500依然是必争之地，尤其是季末阶段，A500冲量明显。从最新规模来看，华泰柏瑞A500ETF自今年6月底跃升至行业第一后，始终保持领先优势；具备先发优势的国泰A500ETF紧随其后；期间包括南方A500ETF、广发A500ETF一度冲至前三，近期易方达A500ETF势头更猛。

十 |                              谁能纳入期权标的？17只产品入围                    基金公司再次在A500ETF上发力或与当下“两交易所各选1只中证A500ETF纳入期权标的”市场传言相关。

十一 | 随着A500ETF产品不断扩容，成为A股举足轻重的宽基ETF，纳入期权标的也是顺理成章，水到渠成。                   纳入期权标的对于ETF而言，相当于按下了规模“加速器”。一般而言，从对冲组合或波动率交易策略角度而言，机构投资者更倾向于选择纳入期权标的ETF进行交易，进而推动该ETF规模增长。有统计显示，以创业板ETF、中证500ETF为例，纳入期权标的后，对应ETF份额短期内增长40%、60%，规模拉动效应显著。                   那么，ETF纳入期权标的需要什么条件？根据深交所发布《深圳证券交易所股票期权试点交易规则》显示，ETF被选择作为合约标的时，应当符合下列四个条件：                    （一）属于本所公布的融资融券标的证券；                    （二）基金成立时间不少于6个月；                    （三）最近6个月的日均持有账户数不低于4000户；                    （四）本所规定的其他条件。                   财联社记者统计显示，当前符合上述条件的A500ETF产品有17只，几乎涵盖了首批A500ETF，这也再次凸显了权益ETF先发优势。                   从上交所上市的A500ETF而言，华泰柏瑞A500ETF胜算最大，最新规模为238.96亿元，2025年半年报显示，持有人户数为2.59万户，年内净流入为31.87亿元，年内资金流入排第一；上交所上市规模排在第二的是华夏基金，当前规模为160.59亿元，持有人户数为3.18万户，同样具备一定的竞争力。

十二 |                    深交所上市的A500角逐更为激烈，该交易所规模第一的是国泰A500ETF，规模为218.83亿元，持有人户数遥遥领先全市场，为10.6万户；与此同时，易方达A500ETF规模上紧随其后，当前规模211.73亿元，持有人户数为2.07万户，年内资金净流入，呈现明显的追赶之势；南方A500ETF也有突围可能，当前规模为195.73亿元，持有户数2.13万户。                   从规模、户数上，上述产品优势更为明显，但是从交易所规则来看，鹏华、嘉实、富国、天弘、博时、泰康、汇添富、摩根、银华、招商、广发、景顺长城等旗下A500ETF均符合要求。可以预见的是，在纳入期权标的未落地之前，规模排序、流动性表现等指标均是加分项，头部产品的鏖战或许也更加激烈。
