北京时间2022年5月20日(星期五)盘后,恒生指数公司将公布恒生系列指数一季度审议结果(审议考察截止日期为2022年3月31日),其中包括恒生、国企、恒生科技等港股主要旗舰指数,以及与港股通可投资范围密切相关的恒生综合指数局部调整。
由于追踪旗舰指数的被动资金规模大(综合彭博和万得资讯的统计,追踪恒指、国企和恒生科技指数的ETF规模分别约为225.2亿美元、48.2亿美元和73.3亿美元),因此潜在成分股变动以及相应资金流向值得重点关注。基于现有可得公开数据,我们预览潜在调整如下,供投资者参考。
恒指调整:关注部分新经济龙头,指数扩容有可能加快
可能调整预览:基于现有数据及指数调整方法,以及通过此前调整结果对系统性优化后的编制方法的理解和验证,我们估算百度集团-SW、快手-W、京东健康、百济神州、中芯国际、翰森制药、哔哩哔哩-SW及中国燃气排在恒生指数顺位前列,有可能成为被纳入的潜在候选者。
我们的测算优先考虑市值顺位,再结合各行业代表性等因素得到。不过,历史经验表明,在实际调整中最终结果可能出入很大,主要是因为一些作为指数咨询委员决策依据的因素,如行业和上市地代表性等并无详细说明或量化依据,更不用说编制方法本身还在持续优化中,因此上述预测只能划定大概的范围作为参考。
潜在权重变化:基于上述预测,我们测算了相应个股可能的权重和资金流向。此外,由于指数设置了8%的权重上限,汇丰控股和友邦保险的权重可能会从当前的8.32%和8.19%被动小幅下调至8%,进而带来潜在被动资金流出。
后续成分股扩容步伐不排除加快。截止目前,恒指成分股为66只,距离2021年3月发布的优化建议中提到恒生成分股将在2022年中前增加至80支的目标还相去甚远。然而回顾2021年以来4次调整结果(2021年1季度增加3只、2季度增加2只、3季度增加4只、4季度增加2只),扩容步伐整体慢于预期。这就意味着,若要实现这一目标,此次季度调整和8月份半年度调整平均每次需要增加7支。如果是这样的话,步伐将明显加快,纳入范围也会进一步扩大。
恒生综指调整:将影响部分港股通标的范围
不同于恒指等其他指数,恒生综合指数调整频率为每半年度一次,故此次只会做局部小范围调整。根据规则,一些符合条件的新上市公司(如一季度新上市并满足恒生综指大型和中型指数纳入条件)可以在此次被纳入,进而进入港股通。根据上述条件、同时综合考虑其他是否可能满足纳入港股通的额外条件,我们测算海螺环保可能符合沪港通纳入标准。
此外已是恒生综指成分股的商汤-W将于今年8月满足纳入沪港通所需的额外上市6个月和20个交易日的条件(2021年12月31日上市),因此我们预计其纳入时间将在今年8月左右。
时间表:5月20日收盘公布,6月13日执行;港股通标的随之调整
时间上,恒生指数公司将于2022年5月20日(星期五)收盘后公布恒生系列指数调整的正式结果,并将于6月13日(星期一)正式实施。在6月13日指数调整生效后,上海与深圳交易所会在随后(具体时间视交易所公布而定)以此为依据相应调整沪深港通的可投资标的范围。
在此期间,与MSCI指数调整类似,部分主动型资金仍不排除会根据调整公布结果采取一定的套利操作,但被动资金为了最大程度上减少追踪误差将选择在生效前一个交易日(即6月10日)调仓。届时相关股票成交会出现远大于平时的「异常放量」情形,特别是在尾盘。
近期港股与资金动向:市场短期盘整磨底但机会大于风险;南向资金加速,海外资金企稳
3月中旬港股一度出现剧烈动荡后,得益于政策维稳信号和中美监管合作的积极进展,市场逐步企稳,进入窄幅震荡的磨底状态。我们预计,虽然仍会有一定波折反复,但恐慌性的抛售已经基本结束,逐步进入结构性的估值修复阶段。未来影响市场走势的一些关键变量包括:
1)中美监管合作与国际地缘局势;2)国内疫情防控进展与对增长的影响;3)稳增长政策的力度与时间。整体来看,我们认为港股的机会仍然大于风险,国内稳增长不断发力(国常会传递降准信号)有助于逐步改善投资者预期和信心。
配置方面,我们认为低估值高股息收益和前期调整幅度较大的优质成长股仍将为投资者在波动中提供更多保护。同时,稳增长板块(部分原材料)有望获得政策支撑。本地金融和消费随着疫情改善也值得关注。
从资金面上看,近期南下资金重回流入,海外资金也有所企稳。
► 南向资金整体维持强劲,近期再度加速。3月中上旬港股动荡期间,南下资金依然逆势流入。除3月17日小幅流出外,自2月23日市场波动开始至3月23日市场企稳反弹的一个月内,南向资金几乎每日维持流入且持续加速,整体流入规模634亿港元,占年初以来整体流入973亿港元的三分之二。
从个股来看,主要流入腾讯、美团-W、李宁、药明生物和快手-W等跌幅较大的新经济个股。3月底南下资金一度有所转弱,3月24至3月30日期间连续净流出。不过4月清明节假期后,南下资金重新加速流入,日均流入6.6亿人民币。
► 海外资金近期有所企稳;前期一度大幅流出可能是波动主因。在南向资金整体流入的大背景下,我们认为前期海外资金流出或是3月中旬市场动荡的主因,其中又以主动型资金流出主导。
不过近期,得益于国内监管维稳信号以及中美监管合作的一些积极进展,海外资金的流出势头有所缓解。基于EPFR统计的数据口径,3月下旬以来(3月24日至今),流入港股的海外被动资金为28.3亿美元,海外主动资金继续小幅流出1.7亿美元,因此整体流入规模总计26.6亿美元。

After Friday, May 20, 2022, Beijing time, Hang Seng Index will announce the results of the first quarter review of the Hang Seng Index (the deadline for review is March 31, 2022). These include major flagship indices such as Hang Seng, state-owned enterprises, Hang Seng Technology and other major Hong Kong stocks, as well as partial adjustments to the Hang Seng Composite Index, which is closely related to the investment scope of Hong Kong stocks.
Due to the large scale of passive funds tracking flagship indices (combined with Bloomberg and Vander Information, the ETF for tracking the Hang Seng Index, State-owned Enterprises and Hang Seng Technology Index is about $22.52 billion, $4.82 billion and $7.33 billion, respectively), so the changes in potential constituent stocks and the corresponding capital flows are worth paying attention to. Based on the available public data, we preview the potential adjustments below for investors' reference.
Hang Seng Index Adjustment: focus on some of the new economic leaders, index expansion is likely to accelerate
The preview may be adjusted:Based on the existing data and index adjustment methods, and through the understanding and verification of the systemically optimized compilation method through the previous adjustment results, we estimateBaidu-SW, Kuaishou Technology-W, JD Health, BeiGene, Ltd., Semiconductor Manufacturing International Corporation, Hansoh Pharmaceutical Group, Bilibili Inc.-SW and China Gas ranked at the top of the Hang Seng Index and could be included as potential candidates.
Our calculations give priority to market capitalization, combined with factors such as the representativeness of various industries. However, historical experience shows that the final results may vary greatly in the actual adjustment, mainly because some of the factors that serve as the basis for the decision-making of the index advisory committee, such as the representativeness of the industry and the place of listing, do not have a detailed or quantitative basis, not to mention that the compilation method itself is still under continuous optimization, so the above forecast can only be roughly delineated as a reference.
Potential weight change:Based on the above forecasts, we measure the possible weights and capital flows of the corresponding stocks. In addition, due to the 8 per cent weight ceiling set by the index, the weights of HSBC Holdings PLC and AIA Group Limited are likely to be passively reduced to 8 per cent from the current 8.32 per cent and 8.19 per cent, leading to potential passive capital outflows.
The pace of subsequent expansion of constituent stocks does not rule out acceleration.So far, there are 66 constituent stocks of the Hang Seng Index, which is mentioned in the optimization proposal issued in March 2021.The goal of increasing to 80 by mid-2022 is still a long way off.. However, reviewing the results of four adjustments since 2021 (3 in the first quarter, 2 in the second quarter, 4 in the third quarter and 2 in the fourth quarter of 2021), the overall pace of capacity expansion is slower than expected. This means that if this target is to be achieved, the quarterly adjustment and August semi-annual adjustment will need to increase by an average of seven. If this is the case, the pace will be significantly accelerated and the scope of inclusion will be further expanded.
Hang Seng Composite Index Adjustment: will affect the scope of some Hong Kong stocks
Unlike other indices such as the Hang Seng Index, the Hang Seng Composite Index adjusts once every half a year, so this time it will only be adjusted locally and in a small range.According to the rules, some eligible newly listed companies, such as newly listed companies in the first quarter and meeting the criteria for inclusion in large and medium-sized Hang Seng Composite Index, can be included this time and then enter the Hong Kong Stock Exchange. In the light of the above conditions and taking into account whether other additional conditions for inclusion in the Hong Kong Stock Connect can be met, we estimateConch environmental protectionMay meet the inclusion criteria of the Shanghai-Hong Kong Stock Connect.
In addition, it is a constituent stock of the Hang Seng Composite Index.Shang Tang-WThe additional 6 months and 20 trading days required for inclusion in the Shanghai-Hong Kong Stock Connect will be met in August this year (listed on December 31, 2021), so we expectIt will be included around August this year.
Timetable: closing announcement on May 20 and implementation on June 13; consequential adjustment of Hong Kong Stock Exchange Standard
In terms of time, the Hang Seng Index Company willMay 20, 2022The official results of the adjustment of the Hang Seng series index will be announced after the close of trading on Friday.June thirteenth(Monday) officially implemented. After the index adjustment takes effect on June 13, the Shanghai and Shenzhen exchanges will then (depending on the announcement of the exchange) use this as a basis to adjust the scope of investment targets of the Shanghai-Shenzhen-Hong Kong Stock Connect.
During this period, similar to the MSCI index adjustment, some active funds still do not rule out taking certain arbitrage operations according to the results of the adjustment, but passive funds will choose to adjust their positions on the trading day before the effective date (that is, June 10) in order to minimize the tracking error. At that time, the trading of relevant stocks will be much larger than the usual "abnormal volume" situation, especially in late trading.
Recent trends in Hong Kong stocks and funds: the market is short-term consolidation, but the opportunities are greater than the risks; southward funds accelerate and overseas funds stabilize.
After the severe turmoil in Hong Kong stocks in mid-March, thanks to the signal of policy stability and the positive progress of regulatory cooperation between China and the United States, the market gradually stabilized and entered a state of narrow shock.We expect that although there will still be some twists and turns, the panic sell-off has basically ended and gradually entered the structural valuation repair phase.Some of the key variables that will affect market trends in the future include:
1) China-US regulatory cooperation and the international geo-situation; 2) the progress of domestic epidemic prevention and control and its impact on growth; 3) the strength and timing of the policy of stabilizing growth.On the whole, we believe that the opportunities for Hong Kong stocks still outweigh the risks, and the steady growth in the mainland (the National standing Committee will send the signal of reserve reduction) will help to gradually improve investors' expectations and confidence.
In terms of configuration, we thinkLow valuation and high dividend yieldAnd those with a larger range of previous adjustmentsHigh quality growth stockIt will still provide more protection for investors in the event of volatility. At the same time, the stable growth plate (partRaw materials) is expected to get policy support.Local finance and consumptionWith the improvement of the epidemic, it is also worthy of attention.
From a financial point of view, recently southward funds have returned to inflows, and overseas funds have also stabilized.
► southbound funds remain strong as a whole and have accelerated again recently.During the turmoil in Hong Kong stocks in mid-early March, southward funds continued to flow against the trend. In addition to the small outflow on March 17, during the month from the beginning of market volatility on February 23 to the stabilization and rebound of the market on March 23, southbound capital inflows maintained and continued to accelerate almost every day, with an overall inflow of HK $63.4 billion, accounting for 2/3 of the total inflow of HK $97.3 billion since the beginning of the year.
From the perspective of individual stocks, mainly into Tencent, Meituan-W, Li Ning Co. Ltd., Wuxi Biologics and Kuaishou Technology-W and other major declines in the new economy stocks. Southward funds weakened at the end of March, with a continuous net outflow from March 24 to March 30. However, after Ching Ming Festival's holiday in April, southward capital inflows accelerated again, with an average daily inflow of 660 million yuan.
► overseas funds have stabilized recently; a large outflow in the early period may be the main cause of volatility.In the context of the overall southward capital inflow, we believe that the early overseas capital outflow or the main cause of the market turmoil in mid-March, which is dominated by active capital outflow.
Recently, however, the outflow of overseas funds has eased thanks to domestic regulatory stability signals and some positive developments in regulatory cooperation between China and the United States. According to EPFR statistics, since late March (since March 24), overseas passive capital inflows into Hong Kong stocks have been US $2.83 billion, while overseas active funds have continued to outflow US $170 million slightly, so the overall inflow totaled US $2.66 billion.
