白宫晚宴上的这一幕,《悲惨世界》经典旋律。不能不联想到背后有安排曲目的意味深长……
《Do You Hear the People Sing?》中文常译“你听见人民在歌唱”或港版填词“问谁未发声”,在2014雨伞运动和2019反修例示威中被大量传唱,大陆主流流媒体一度下架英文原曲。
香港教育部门后来禁止学校演唱带政治信息的歌曲,更著名的《愿荣光归香港》后来被法院禁制。
所以这首曲在中方官员耳朵里,应该比普通百老汇名曲更刺耳。这次现场主唱的是同一部剧里的《One Day More》,只是掺进了前一首的旋律和歌词碎片,没有把整首“人民在歌唱”完整唱出来。
这首歌在剧情中的位置,恰恰是学生革命者准备起义前夕。
没文化很可怕,也许,在礼炮与红毯之下,也深埋着嘲讽与暗喻……

一个美股的死亡数据触发了
[指数和VIX同时上涨]
QQQ 当天涨幅 +2.75,且 VXN 纳指波动率指数+1%
1)过去 20 多年里仅出现过 12 次(集中在 2000–2003 年互联网泡沫破裂期、2008 年金融海啸、2009 年大底震荡期以及 2023 年初)
2)12 次中后两周下跌概率为 100%,中位数跌幅为 -4.82%。
3)未来一个月回报,12 次中仅有 2009 年 6 月微涨了 +0.17%,其余 11 次全部下跌,中位数跌幅为 -5.88%。在 2008 年雷曼破产后曾单月再暴跌 -24.70%,2000 年 10 月单月暴跌 -21.66%。
4)未来 5 天最大回撤中位数达到 -6.2%,极端情况下 5 天内回撤超 -10%(如 2000 年 10 月、2001 年 4 月、2002 年 6 月)
为什么“指数大涨 + 波动率涨”可能是暴跌前兆?
1)极端逼空与空头踩踏
这种单日近 3% 的狂飙往往不是长线机构的建仓买盘,而是前期积累的大量空头头寸被拉爆引发的无差别止损平仓。缺乏真实基本面承接的逼空反弹一旦力竭,流动性瞬间真空,往往直接诱发二次探底甚至加速破位。
2)期权市场在“恐慌性买入保护”
现货虽然在涨,但机构大资金不仅没有解除对冲,反而因为对系统性风险或后续事件极其焦虑,在期权市场上不计成本地扫货买入深虚值看跌期权(Put)或波动率多头。巨大的期权买盘需求直接推高了全期限的隐含波动率(IV),导致 VXN 在指数大涨的日子出现反常暴拉。
3)高波动率是熊市特有的DNA:
观察这 12 次事件的年份分布:2000 年 10 月、2001 年 4–5 月、2002 年 6–7 月、2008 年 9 月。
历史上最凶猛的单日大阳线,绝大部分都诞生在深度熊市或重大危机中。在熊市里,单日脉冲式暴涨往往是资金借反弹减仓、主力掩护撤退的典型窗口。
策略应对:
1)切忌在短线大阳线中盲目追高美股科技股:历史数据显示该形态触发后 5 天内平均面临 -6% 以上的回踩考验。
2)波动率对冲的天然时机:如果手中持有高估值科技股现货,面对波动率上升,可借反弹拉升执行期权领口策略对冲。

$SPY Weekly post.
My framework this week is actually pretty simple.
First, the bigger picture:
The FOMC lows are my line in the sand.
After the dividend adjustment, that area is roughly 745–747.
As long as SPY holds above that zone, I’m treating the broader market structure as bullish.
I don’t care how ugly the headlines look.
Yields are elevated. Oil is high. Geopolitical risk remains ugly. The Fed is tightening.
And despite all of that, the market keeps holding.
At some point you have to trade the price in front of you rather than the story you think should move it.
So until 745–747 breaks, bulls still have the benefit of the doubt.
That doesn’t mean I’m blindly buying calls.
Actually, after this morning’s gap up, the short setup is closer to me than the long setup.
I’m watching 770–773 as my main resistance/short zone.
Ideally, I’d like SPY around 771–772. If I get the right rejection/weakness there, I’ll look for a swing short with invalidation just above the zone.
If weakness shows up a little earlier around 770, I may take it there.
I’m not interested in shorting much lower than that.
The idea isn’t “the market is crashing.”
It’s simply a tactical pullback from major resistance, with roughly 761–762 as the area I’d initially want to target.
That’s the type of setup I like:
Enter close to resistance, keep invalidation close, and leave enough room underneath for a meaningful move.
If SPY clears 773 and starts accepting above it, I’m not going to fight it. At that point, we’re likely looking toward the ATH again and the short thesis is invalidated.
On the other side, if SPY never reaches my short zone and sells off without me, that’s fine too. I’ll wait.
A move back close to the FOMC low 745–747 area would put the long side back on my radar.
If that support holds again, I’d be interested in another swing long.
If it decisively breaks, that’s when my broader market view changes bearish and I’d stop looking to buy the dip.
So there are really only two areas I’m interested in:
Higher ->770–773: look for a tactical short.
Lower -> 750-747: look for another long.
Everything in between can happen without me.
There are two other things I’m watching.
VIX is back below 15 and approaching the 13.8–14 area that has repeatedly acted as support. That doesn’t guarantee an equity pullback, but combined with SPY approaching resistance, it makes me more interested in watching for one rather than chasing upside here.
And $QQQ may be setting up something very interesting.
QQQ is gapping toward the old open gap around 729–730 this morning.
If it opens above that area and, importantly, keeps today’s new gap below it open, we’d potentially be looking at an island bottom structure.
That would be a legitimately bullish development.
If QQQ confirms that structure and starts running, I have to respect the possibility that tech leads the broader market higher and drags SPY through my resistance zone instead of rejecting it.
So I’m not married to the short.
Price decides.
For now, my bias above the FOMC lows remains bullish, while my next potential trade is actually a tactical short if SPY gives me the right setup around 770–773.
Sounds contradictory, but it isn’t.
You can be bullish on the broader structure and still short a defined move from major resistance back toward support.
And if neither of my levels comes?
I stay cash.
I don’t need to trade the middle.
I don’t need a trade every day.
Give me my level, give me my confirmation, give me tight invalidation.
Otherwise, it can do it without me.

老人味,其实是浊气,一个方法,清浊气,自然香
家里有老人的都懂这种说不出的尴尬,老人自己完全闻不到身上的怪味,旁人离得两三米远就能察觉到。
尤其是小孩子鼻子灵,每次老远就躲着跑,老人嘴上不说,心里别提多难受了。
之前我也以为是老人年纪大了懒得洗澡,直到做中医的朋友点醒我,真的错怪他们了。
人上了年纪之后皮肤代谢速度大幅下降,皮脂分泌的物质慢慢氧化,就会散发出一股类似旧汽油的酸馊味。
老祖宗的《黄帝内经》早就把这种积在体内排不出去的脏东西叫做浊气,光靠洗澡擦身子根本去不了根。
调理方法特别简单,根本不用花大价钱买保健品。
抓一把干茉莉,一把陈皮,再加适量茯苓,丢进锅里加水煮15分钟就成。
很多人管这个叫体香茶,也戏称它是排浊水。
平时就当普通茶水喝,慢慢把体内积的浊物排干净。
我外婆之前坚持喝了小一个月,现在凑到她身边唠嗑,全是淡淡的自然清香味,再也没有之前那股怪味了。
好多人跟家里老人说这个法子,老人还不信,觉得你乱花钱瞎折腾。
别费口舌劝,直接把材料备齐煮好端到他们跟前,喝上一阵子,效果自己就出来了,啥解释都多余。

如果你手里有一份来路不明的软件,想知道它到底在背后偷偷干了什么……你不需要花几万块买商业软件。
你只需要打开这个来自美国国家安全局(NSA) 的官方逆向工具——Ghidra。
这本来是 NSA 用来抓病毒、找漏洞的国家级装备。里面藏着他们十多年积累的团队协作逆向技术 。
现在 GitHub 上直接免费下载。
重点来了, 这东西支持几乎所有你知道的操作系统(Windows、Mac、Linux),甚至能分析路由器和物联网里的芯片 。
最细思极恐的是,早在 2017 年维基解密曝光的 Vault 7 文档里,CIA 就提到过 NSA 一直在偷偷用 Ghidra 。
微软这个开源语音项目 VibeVoice,有点厉害的。
60 分钟的会议、播客或访谈,可以整段直接丢进去语音识别,不用切成几十个小片段。
输出也不只有文字,还会直接整理出:
谁说的 + 什么时候说的 + 具体说了什么。
还支持自定义人名、术语等热门词汇,覆盖 50+ 语言。
VibeVoice-ASR-BitNet 又把模型从 4.62GB 压到 1.58GB,CPU 3 个以上线程即可实时推理,不需要 GPU。
另外还有 0.5B 的实时 TTS,首声延迟约 300ms,支持流式输入和约 10 分钟连续语音生成。

关闭了杀熟功能 当晚机票就降了
订机票前记得刷新
白天刷到560的时候我是真的想放弃了
半夜顺手开无痕查了一下252!!!
降价了将近一半 这是什么神仙体验
我是这样做的👇
1.打开订票APP的无痕搜索
关掉搜索记录 清缓存
2.等到晚上10点以后再查
我一般11点蹲 降价概率最高
3.觉得合适就果断下单
千万别反复刷 越刷越贵是真的
白天看太贵的话
真的别冲动买
等到晚上再查一次 大概率会回落

Here is the S&P 500 heat map as we head into the eve of FOMC tomorrow.
This is NOT the type of underlying weakness you want to see if you're a bull, especially with one of the biggest potential catalysts of the month sitting directly in front of us.
The indexes can still push higher while weakness continues building underneath the surface, which is exactly why I'm not interested in chasing anything here.
If they give us 770-773, I'll take it as a gift and an opportunity to add to my positions.
Let them push it up if they can. Let them fill the gaps if they can. Let everyone get more comfortable.
Then we see what FOMC gives us.
