MRVL stock | Oct 15 2026 | 1 min chart | 5 min chart | Maximum profit, best time to trade, should give those people a blog to read and motive with more courage | Share with courage to build wealth
My trades on MRVL stocks
My gain on MRVL stocks
- 3 trades
- Total gain: $341.12 US dollars
- Only worked on 5 min chart first 8 bars, 40 minutes
- There is strong uptrend coming with impulse leg
5 min chart
But I was lack of motiviation to continue and make more trades based on positive thinking. It was so sad to see good trades wasted.
3.68 ATR impulse leg came after bar count No. 10
Let me quickly review those possible trades, how to read charts, and how to maximize the profit and finance risk using existing profit trades in the same day.
Work on first FVG - 5 min retracement - $230/ share - bar coun No. 79 and 80 and prepare next FVG at bar count 82
Do not give up on MRVL stock and should continue to work on rest of time to market close
1. Should work on 250 shares of MRVL on the following chart
Trade
- 2 bar 10 minutes
- 5.1129 (2.22%)
- Use existing profit to finance risk - $340 US dollars
- Profit maximum: 5 * 250 = 1250 US dollars
- Should start at 7:40 AM PST
- Always remember that it is hard working to deserve those profits, and alway take some risk if there is some gain on previous trades in the same business day
- Always think positive, a lot of trader rushed to stay in AI stocks, and also rushed to cut loss when panic, and it is best time to pick up those shares when uncertainties are so many and you can not tell what is next, uptrend or downtrend
- Trade 2
- Idea is to wait MRVL stock to test FVG half line underneath bar count No. 16
- 4.7272 x 250 shares 2.02%
- 6 bars 30 min
- Profit maximum: $1250 US dollars
- Consider if you take risk to take trade 1 with over $1000 US dollars gain
Stock market can give you 30 minutes 5.15/ share profit from MRVL stock, I can use my margin accoun t to purchase up to 250 shares.
Do not give up, continue to trade again after retracement back to red pivot point near bar count NO. 37 $234.60/ share
15 min chart
15 min chart
5 min chart
- Remember one thing if MRVL stock is at lowest price, it is much easy to make profit and easy to take risk
- Do not give up even though rebound is showing not so strong, but you have to be patient and then go through every step to make profit as big as possible
- Compared to Dell, CRDO and other AI stocks, MRVL is much easy one to take more swing trades and then make profit on Oct. 15 2026
- I quit too early and only traded from 6:30 AM To 7:20 AM

rklb stock dropped 8% after market close, why? in chinese
火箭实验室(Rocket Lab, 代码:RKLB)股价在盘后交易中大跌约8%,主要原因如下:
- 中子号(Neutron)火箭首飞延期至2027年:公司宣布将原定于2026年第四季度进行的中子号中型可重复使用运载火箭首飞推迟到2027年。 [1]
- 制造问题:延期的核心原因是火箭第一级推进剂贮箱的碳纤维复合材料部件遇到了制造问题,需要进行重新设计和工艺调整。 [1]
- 高管内部减持压力:10月初首席财务官亚当·斯派斯(Adam Spice)根据预先安排的交易计划抛售了约990万美元的股份,叠加此前高估值担忧,市场情绪本来就较为脆弱。 [1]
- 宏观市场环境不佳:受美国9月份消费者价格指数(CPI)加速上涨影响,纳斯达克指数当天大跌约1.9%,高成长和科技股普遍承压。 [1]
如果你想了解更多,可以告诉我:
- 你是RKLB的长期投资者还是在做短线交易?
- 是否需要分析中子号延期对它竞争对手(如SpaceX)格局的影响?
MU stock and other AI stocks dropped after today market close, any update after market close, just panic. IN chinese
针对美光(MU)及其他AI、半导体板块的下跌,最新市场动态与核心原因如下:
- 中国存储芯片商进展引发恐慌:中国长鑫存储(CXMT)近期在上海活动上宣布,在高密度存储单元架构(4F² 结构等)上取得进展,并计划在今年底前推出相关服务器内存产品。这引发市场担忧全球内存供给可能增加、进而挤压美光、SK海力士及三星等巨头的定价权与利润空间。 [1, 2, 3, 4, 5]
- 全板块与AI交易降温:不只是美光(周二收在约 $953.19,下跌约 4% 左右并连续多日调整),韩国的SK海力士、三星,以及美股的英伟达(NVDA)、AMD、闪迪(Sandisk)、西部数据等AI与半导体产业链股票均普遍承压。市场对前期大幅上涨后的估值、AI基建回报周期以及融资成本产生顾虑。 [1, 2, 3, 4]
- 分析师观点:情绪宣泄大于实质威胁:多位行业分析师指出,长鑫存储在高端HBM(高带宽内存)等核心技术与大规模量产能力上,短期内仍难以对美光等构成颠覆性威胁。当前的大跌更像是美光等股票今年涨幅巨大后,市场借“中国芯片消息”进行获利回吐和情绪化抛售,类似于去年的“DeepSeek恐慌”。 [1, 2, 3, 4, 5]

nke stock rebounded from bottom after earnings, any update. In Chinese
Nike (NKE) 在 2026 年 10 月初公布了 2027 财年第一季度财报后,并没有出现真正的强势反弹,反而由于大中华区业绩疲软和对 2027 年营收指引保守而持续受压。 [1, 2, 3]
最新市场动态与财报情况:
- 财报表现:虽然每股收益(EPS)为 0.48 美元(略高于预期的 0.44 美元),但营收为 112 亿美元,同比下降 4%,低于华尔街预期。
- 中国市场(Greater China):大中华区营收大跌 26% 至 11.8 亿美元,加上传出计划限制中国主要经销商在线销售等传闻,引发市场对中国业务战略的担忧。
- 机构评级:财报后,UBS、BofA(美国银行)、JPMorgan 等多家机构纷纷下调了 Nike 的评级或目标价,认为其转型需要比预期更长的时间,短期内难以快速复苏。
- 股价走势:股价在财报发布后一度大跌(盘后暴跌约 9%),并未形成有效的触底反弹,目前整体仍在多年低位附近徘徊。 [1, 2, 3, 4, 5, 6, 7]

VZ stock | $41.29 1000 shares at the bottom | Should hold for a few days - position trade
VZ stock
- VZ stock may rebound any time in any form, overnight, any catalysts unpredictable
- Bought 1000 shares at $41.09/ share at 8:52 AM PST on Oct. 9 2026
- Should hold for a few days, ignore up and downs, for maximum benefit of uptrend swing
Oct 9, 12, 13 three days - I traded but I only have $500 US dollars gain
If I choose to hold for three days, the gain will be more than $2000 US dollars.
I cannot beat the market because I have to deal with emotions and also unpredictable swings.
