铠侠计划投资超1万亿日元在岩手县建设新NAND闪存工厂，与Sandisk联合，预计2029年后投产
同一催化（日经报道铠侠岩手1万亿日元NAND新厂）在案例库中已出现4次AVOID记录（2026-08-26至27）；285A.T当日已涨+4.4%表明市场正在实时定价；投资时间线为2029年后，无近期收入增量；我们历史在285A.JP上13笔ENTER仅31%胜率、中位收益-5.66%，反复追高被套；综合判断无正期望可交易窗口

不做 Kioxia Holdings（285A.JP）
同一催化已被处理4次均为AVOID；股价当日已涨+4.4%（市场正在实时定价）；2029+投产时间线无近期收入增量；我们历史在该票13笔ENTER胜率仅31%、中位-5.66%，追高模式反复亏损；供给端扩产公告非需求验证，无正期望短线交易窗口
不做 Sandisk（SNDK.US）
美股已收盘且盘后已涨+3.7%；联合投资方但投资金额相对市值占比有限；2029+时间线无近期催化；我们历史在SNDK上多次追高亏损（-11.5%、-3.1%）
不做 东京电子（8035.JP）
设备订单落地要到2028-2029年，当前无交易级催化；当日仅涨+0.67%表明市场未将此视为近期利好；时间线过远无法构成短线交易逻辑

结论摘要
日经独家报道铠侠拟投资超1万亿日元在岩手建NAND新厂（2029+投产、与Sandisk联合、获政府补贴）。这是供给端产能扩张公告而非需求验证，投产时间线3年以上，无近期收入贡献。285A.T当日已涨+4.4%，SNDK盘后涨+3.7%，市场已在定价。我们案例库显示同一催化已被处理4次均为AVOID，且我们在该票历史胜率仅31%。设备供应商（东京电子）订单落地也要等到接近投产期，当前无交易级催化。

先例如何影响了这次决策
对本次决策的影响:自有案例库的反复亏损记录强化了AVOID判断，不改变方向但确认无正期望
方向:无足够外部先例；但自有案例库显示同一催化4次AVOID、历史13笔ENTER胜率31%中位-5.66%
涨幅量级:无高相似先例可校准幅度
形态:案例库显示我们反复在285A.JP上追高被套（-8%、-11%、-5.7%），模式为高开追入后次日回落

TOKYO -- Memory chip maker Kioxia Holdings plans to build a new production facility at its plant in northern Japan, with investment in the project expected to top 1 trillion yen ($6.27 billion), Nikkei has learned.
Top Kioxia executives are set to visit the prime minister's office on Thursday to announce the new construction plan. At an investor briefing in June, Kioxia President Hiroo Ota said discussions about a new facility had begun, with an eye to start operations in 2029 or later.
The new facility will mass produce NAND flash memory, which is used for long-term data storage. Kioxia currently manufactures memory chips at its plants in Mie and Iwate prefectures.
The planned third building will located at the Iwate location. Kioxia has already begun approaching some suppliers, including equipment manufacturers, about purchases for the new facility. It is also expected to make use of subsidies from Japan's Ministry of Economy, Trade and Industry.
Kioxia ranks third globally in NAND market share on a value basis, behind South Korea's Samsung Electronics and SK Hynix. With both South Korean companies announcing major investments in domestic production, attention had turned to Kioxia's next move. The Japanese memory maker will invest jointly with U.S.-based Sandisk.
Kioxia's new domestic investment aligns broadly with the Japanese government's push to promote domestic semiconductor production. Tokyo views chips as a strategic commodity key to economic security.
