Trading Viewpoint: Technical signals indicate a short-term bearish outlook for semiconductors, with the South Korean KOSPI index, a leading indicator, having fallen below its 50-day moving average.
According to BlockBeats, on July 3rd, trader 3X Long Labubu stated that he is bearish on the semiconductor sector in the short term based on technical signals, especially memory and semiconductor equipment. He has already liquidated his holdings in these areas and shifted his focus to more defensive sectors such as software and the seven major US stock market giants. His specific rationale is that the Korean KOSPI index, often used as a leading indicator of the semiconductor cycle, has fallen below its 50-day moving average, and Micron Technology has also fallen below its 21-day moving average. The trader plans to reassess the situation next week. If Micron Technology (MU) regains its key support level, he will automatically buy back to cover his losses using a stop-loss order.
Multiple Wall Street firms are collectively advocating for "buying on dips" in the semiconductor sector: the long-term logic of AI remains unchanged, but investment is entering an era of selective buying.
According to Mars Finance, on July 7th, amidst the recent continuous correction in the semiconductor sector, several Wall Street institutions have voiced their opinions, generally believing that the current adjustment presents an opportunity for investors to "buy on dips." However, unlike past recommendations to allocate across the entire semiconductor sector, institutions generally believe that AI investment has entered a phase of selective stock picking. Goldman Sachs stated that AI chip trading has entered a more selective phase, and does not recommend continuing to "buy a basket" of semiconductor stocks. They remain optimistic about specific sub-sectors such as CPUs, ASICs, memory, and semiconductor equipment, specifically highlighting AMD and Applied Materials. JPMorgan Chase believes that the recent correction in semiconductor stocks presents a good entry window, as AI chip demand remains in a long-term upward cycle, with new capacity not expected to be significantly released until around 2028, and the industry's supply and demand structure remains healthy. Bank of America maintains its optimistic outlook on the long-term boom cycle of AI semiconductors, believing the industry is still in the middle of an 8- to 10-year growth cycle, and the global semiconductor market size is expected to continue to expand. They recommend focusing on industry leaders such as Nvidia, Broadcom, Lam Research, and KLA. UBS stated that the long-term investment logic for AI remains unchanged, and the short-term fluctuations in the semiconductor sector actually provide long-term investors with opportunities to gradually build positions. They recommend taking advantage of market corrections to buy on dips. Morgan Stanley believes that the long-term prospects for AI chips remain positive, but with the sector's significant rise, the market will focus more on earnings realization capabilities. Funds may gradually rotate from some chip stocks to AI infrastructure beneficiaries such as cloud computing, and investors should pay more attention to individual stock selection. Overall, several Wall Street institutions, including Goldman Sachs, JPMorgan Chase, Bank of America, and UBS, have recently released similar signals: the semiconductor correction is not the end of the AI rally, but rather provides a new window for investment. However, the market has moved from a phase of "broad-based sector gains" to one of "selecting leading companies," and future performance will depend more on companies' earnings realization capabilities and the sustainability of demand for AI infrastructure.
US stocks saw the Nasdaq under pressure in overnight trading, but the semiconductor and memory sectors rebounded strongly, with memory chains leading the gains among tech stocks.
According to Mars Finance, on July 6th, based on BIT (bit.com) market data, the three major US stock indices diverged in overnight trading. The Dow Jones Industrial Average rose 1.14%, the S&P 500 was essentially flat, and the Nasdaq Composite fell 0.8%. Market structure indicates that funds continued to rebalance within growth stocks, with traditional heavyweights and value sectors showing relative strength. Within the technology sector, however, divergence and volatility were observed, although the semiconductor and memory sectors clearly exhibited independent rebounds, driven by the need for valuation repair after previous corrections. NVIDIA (NVDA) rose 0.17%, TSMC (TSM) rose 2.11%, Marvell Technology (MRVL) rose 1.94%, Seagate Technology (STX) rose 3.39%, Western Digital (WDC) rose 4.91%, SanDisk (SNDK) rose 5.85%, and Micron Technology (MU) rose 4.36%.
