1. Report Industry Investment Rating - No relevant content provided 2. Core Viewpoints of the Report - In the context of continued positive policy and valuations reaching the 80%-90% percentile of the past decade, attention should be focused on the capital market and the prospects of the technology sector. The unilateral strategy is to go long at low levels, and the arbitrage strategy is to go long on the main contracts of IM/IC and short ETFs for cash-futures arbitrage [5][6][45] 3. Summary Based on the Table of Contents 3.1 Second Part: Market Review in October 3.1.1 Stock Market - First Decline, Then Rise, and Reach a New High - In October, the A-share market first declined and then rose, with the stock index reaching a new high after oscillations. By October 29, the monthly increase of the CSI 300 Index was 2.3%, the SSE 50 Index rose 2.48%, the CSI 500 Index rose 0.93%, and the CSI 1000 Index fell 0.08% [10] - The oscillations in the stock index led to prominent performances in traditional industries. Sectors such as coal, insurance, telecommunications, public utilities, and oil and gas had significant increases, while sectors like media, automotive, healthcare, computer, real estate, and food declined. The technology sector showed differentiation, with high-level oscillations in concepts such as optical modules, domestic chips, advanced manufacturing processes, and humanoid robots [12] 3.1.2 Stock Index Futures - Periodic Expansion of Premium and Decline in Trading Volume and Open Interest - In October, the premium of stock index futures expanded periodically compared to the previous month. Especially after the listing of the 2606 contract, the premium of the quarterly contracts of IM, IC, and IF expanded significantly, while the premium of the current-month contracts slightly decreased overall, and the basis of each IH contract remained stable [16] - The trading volume and open interest of stock index futures declined overall in October. The average daily trading volume of IM, IC, IF, and IH decreased by 14.4%, 4.1%, 12.6%, and 3.8% respectively; the average daily open interest of IM, IF, and IH decreased by 4.9%, 3%, and 3.8% respectively, while the average daily open interest of IC slightly increased by 0.4% [23] - The expansion of the premium increased the rollover cost for short positions in stock index futures. The optimal choice for short positions in IM and IC to roll over to the next-month contracts had the lowest cost, with the average monthly annualized costs being 9.55% and 8.12% respectively, increasing by 0.82 and 0.59 percentage points compared to the previous month. The optimal choice for short positions in IF and IH to roll over to the next quarterly contracts had the lowest cost, with the average monthly annualized costs being 2.52% and 0.16% respectively, increasing by 0.32 and 0.23 percentage points compared to the previous month [27] - From the perspective of the open interest of major seats, the open interest of each variety remained stable overall, but the net short positions in IC increased significantly. The average monthly net short positions of the top five and top ten seats in IC increased by 2.1 and 2.5 percentage points respectively compared to the previous month. In addition, at the end of September, facing the National Day holiday, the short positions in IF significantly increased before the holiday and then quickly decreased after the holiday, indicating the hedging operations of investors using stock index futures [29] 3.2 Third Part: Market Outlook and Investment Strategy 3.2.1 What's Different About Reaching 4000 Points Again - On October 28, the Shanghai Composite Index stood above the 4000-point mark again after a decade, which was the third time since May 9, 2007, and April 8, 2015. Compared with the previous two times, this round of market has both similarities and some obvious differences [34] - In 2007, the first time the Shanghai Composite Index reached 4000 points was in the middle and later stages of the 2005 - 2007 bull market, driven by the split-share structure reform policy. Corporate profits improved in line with the macroeconomy, leading to a comprehensive bull market [34] - In 2015, the second time the Shanghai Composite Index reached 4000 points was in the later stage of the 2013 - 2015 bull market. Due to the quantitative easing policy implemented by the US at the end of 2012 and multiple reserve requirement ratio cuts and interest rate cuts in China, the liquidity in both China and the US was loose, and the margin trading in A-shares was active, resulting in a structural market driven by industrial upgrading [34] - Currently, the macroeconomy still faces significant uncertainties, but the artificial intelligence industry chain has experienced explosive growth. The ETF market has expanded significantly, and the absolute value of margin trading balance has continuously reached new highs. The proportion of margin trading is still far lower than that in 2015, and the market is generally stable. The policy is still to "fully consolidate the stable and improving trend of the market," and the development prospects of emerging industries are still broad. Therefore, this round of market is more similar to that in 2015, and the capital market and the prospects of the artificial intelligence industry will determine the height of the market [35] 3.2.2 The Third Quarter Reports to Test the Bull Market - As of October 31, 5437 companies announced their performance, and the overall third-quarter reports of listed companies showed an increase, adding confidence to the bull market. The total operating income of all A-shares reached 53.3 trillion yuan, a year-on-year increase of 1.21%, and the net profit attributable to the parent company reached 4.7 trillion yuan, a year-on-year increase of 5.34%, breaking away from the downward trend of the previous two quarters [40] - It should be noted that the 11.31% increase in the single-quarter net profit attributable to the parent company in the third quarter reports is related to the low base in the third quarter of last year (-15%), which is consistent with the continuous monthly increase of over 20% in the profits of industrial enterprises above the designated size from August to September. With the PMI remaining below the boom-bust line for six consecutive months and the order backlog index remaining at around 45%, the full-year performance still needs continuous tracking and observation [42] - For the performance growth of industry sectors that A-share investors are more concerned about, there have been some changes. Since April, the artificial intelligence wave has led to a significant increase in the performance of the semiconductor industry chain, forming a "Davis double-click" and stimulating market sentiment. However, among the three leading companies in the optical module (CPO) sector, the single-quarter operating income of two companies decreased quarter-on-quarter in the third quarter, and the net profit attributable to the parent company hardly increased quarter-on-quarter. Affected by this, the stock prices of relevant companies fell sharply, the sector declined, and the stock index was also affected. If the performance of the NVIDIA industry chain continues to fall short of expectations, attention should be paid to the progress of the domestic chip industry chain and the performance implementation of the robot industry [43] 3.2.3 Future Strategies - Based on the above analysis, in the context of continued positive policy and valuations reaching the 80%-90% percentile of the past decade, attention should be focused on the capital market and the prospects of the technology sector. Under the premise that the above factors remain unchanged, the unilateral strategy is to go long at low levels. Stock index futures investors should pay attention to the year-end convergence rule of the premium of IM/IC/IF, and the arbitrage strategy is to go long on the main contracts of IM/IC and short ETFs for cash-futures arbitrage [45]
