Regarding SanDisk and Micron Technology, I've previously shared many views involving technicals, performance, and other indicator parameters. Today, on the weekend, I'll organize my thoughts and discuss with everyone from the perspectives of macroeconomics, industry, and the securities market. ///It's already a market consensus that AI will dominate this era. We are all gathered here because we are optimistic about the development of AI. The topic naturally revolves around NVIDIA. NVIDIA is already approaching a $5 trillion market cap, with a forward P/E ratio of about 25x. This is the benchmark. The so-called AI bubble theory is basically over. ///The hottest stock in the current AI industry chain is not NVIDIA. It's not that NVIDIA is bad, but it was already hot before. Now, it's because of issues with market cap headroom, the sustainability of AI infrastructure investment scale, and edge competition.///What's hottest now is the shortage in NVIDIA's upstream supply chain: memory shortage, surging demand for optical interconnect industry chains, and power supply bottlenecks. This is already reflected in the market, no need to doubt it anymore! ///Back to memory, it's the cycle theory and moat theory that plague the market. I believe neither exists in the AI era. The memory shortage cannot be solved in one or two years. The expansion speed of original manufacturers is far behind the growth rate of demand. Any product that China can manufacture will become fiercely competitive in the future, as seen in cases from photovoltaics to electric vehicles. There is no real moat. However, the moat for memory is the widest. Due to the limitations of lithography machines, our generational gap in AI memory is getting larger, not smaller. It's the same for GPUs and xPUs. The production capacity bottleneck for memory is becoming increasingly prominent. ChangXin Memory's Shanghai factory production won't exceed a 5% market share, and Yangtze Memory's target is a 15% market share by the end of 2028. Note that even with this market share, it won't have a say in the AI memory field due to the generational product gap issue. A 30% market share is the bottom line for self-sufficiency. Don't just look at media reports; many are not accurate. ///Speaking of SanDisk and Micron Technology, US-based memory companies. SanDisk has always been far ahead in NAND technology. It just had no use in the consumer electronics era. Now, in the AI era, it's been reborn, from the highest-performance SSDs to the emergence of HBF. The sharp rise in its stock price is not emotional speculation. Its current stock price corresponds to a forward P/E ratio of only around 9x for 2026. SanDisk is undergoing a valuation reset. Micron Technology is severely undervalued due to the profit balance issue of intermediaries in the stock market. I believe the market will correct this deviation. It's too cheap. In the AI era, I think you can close your eyes and buy stocks with single-digit P/E ratios, not fearing short-term fluctuations and holding for the medium term. Short-term market volatility won't change the medium-term trend!///The Nasdaq hitting a new all-time high in one go is a signal of repeated upward movement. Musk wants to make chips, and it's not without reason. From AI chips to memory, there's a severe shortage. The memory market's journey is still long. Let's proceed and cherish it!" datetime: "2026-04-19T04:51:09.000Z" locales: - [en](https://longbridge.com/en/topics/40022648.md) - [zh-CN](https://longbridge.com/zh-CN/topics/40022648.md) - [zh-HK](https://longbridge.com/zh-HK/topics/40022648.md) author: "[昆仑山岩石](https://longbridge.com/en/profiles/15670421.md)" --- # $Sandisk(SNDK.US)$Micron Tech(MU.US)The trend is b… ### Related Stocks - [MU.US](https://longbridge.com/en/quote/MU.US.md) - [NVDA.US](https://longbridge.com/en/quote/NVDA.US.md) - [SNDK.US](https://longbridge.com/en/quote/SNDK.US.md) - [.IXIC.US](https://longbridge.com/en/quote/.IXIC.US.md) - [SNDKV.US](https://longbridge.com/en/quote/SNDKV.US.md) - [NVD.DE](https://longbridge.com/en/quote/NVD.DE.md) ## Comments (19) - **昆仑山岩石 · 2026-04-22T20:52:00.000Z**: Woke up to find that SanDisk and Micron Technology both rose about 8.5%, and they're still climbing after hours. The main trend is volatile upward movement. Looking forward to SanDisk hitting $1000 and Micron Technology's stock price reaching $500 tonight. Of course, this is bound to happen sooner o - **win755 · 2026-04-20T22:58:41.000Z**: Strong - **半山外賣仔 · 2026-04-20T09:34:08.000Z · 👍 1**: Continue to support 🪨 Brother Rock - **步履不停的梭哈 · 2026-04-19T16:04:07.000Z**: Blogger, is Samsung okay? I've always been bullish on the South Korean leadership and the memory market, feeling that SK Hynix and Samsung haven't fully exerted their strength yet. - **昆仑山岩石** (2026-04-20T00:41:56.000Z): Being in the top 2 in terms of storage scale is certainly good, but that's the Korean stock market, and it's still different from U.S. stocks. - **会止损不瞎搞哈 · 2026-04-19T14:13:55.000Z**: If Micron doesn't rise, it's killing the options. There are too many people bullish on it. However, there will be a violent rebound sooner or later, taking off directly, rising 10% in a day and over 50% in a week, waiting for the Q3 earnings report. - **爱妻的交易员 · 2026-04-19T10:25:59.000Z**: Brother Yanshi's analysis is great👍🏻 - **Mr sen · 2026-04-19T09:21:44.000Z**: Thanks for the output - **W时空 · 2026-04-19T06:40:47.000Z**: I got 2x leverage, can I hold it for the long term? I've already held it for over a month. - **昆仑山岩石** (2026-04-19T07:09:59.000Z): I have always been cautious about leveraged products. The volatility is too high and there is also decay, which affects the mindset of holding stocks. For varieties like SanDisk and Micron Technology, - **W时空** (2026-04-19T07:14:20.000Z): Then I'll wait for the earnings report to come out, clear all my positions, and switch to the underlying stock. - **Debruyy** (2026-04-19T07:57:49.000Z): The volatility is too high, the returns from a 2x leveraged product are not significantly higher than the underlying stock, and you might even get harvested individually because you can't hold on to i - **光辉万丈 · 2026-04-19T05:53:56.000Z**: Completely agree with Brother Rock's point of view👍 - **不甜， · 2026-04-19T05:38:54.000Z**: Bro, your articles have always been the motivation for me to hold onto SanDisk firmly.I think my ability is not enough. So I don't even do swing trading, waiting for it to pull back again this time, I'll continue to average down according to my 850/780/740/700 plan. - **不甜，** (2026-04-19T05:39:51.000Z): My cost basis is 588. I didn't sell a single share during these two deep corrections. - **OUOUbaba** (2026-04-23T04:05:08.000Z): Excellent
