美国主要股指最近急剧下跌 $道琼斯指数(.DJI.US$, $纳斯达克综合指数(.IXIC.US$, $标普500指数(.SPX.US$ 是由抛售推动的 $Facebook(FB.US$ 和其他大型科技股 $谷歌-A(GOOGL.US$, $亚马逊(AMZN.US$, $苹果(AAPL.US$, $微软(MSFT.US$, $奈飞(NFLX.US$, $英伟达(NVDA.US$。在社交媒体股票中 $Pinterest(PINS.US$, $Snap Inc(SNAP.US$, $Twitter(已退市)(TWTR.US$,的股份 $Facebook(FB.US$ 由于一系列负面披露和政治影响,跌幅最大。由于服务器出现问题,该公司在其整套服务上出现了近十年来最严重的暴行,这加剧了其最近的困境。由于其大部分收入来自其多个平台上的广告,这种愤怒可能使该公司蒙受了数百万美元的收入损失,尽管与明年的预期收入相比,这种亏损微不足道。这种愤怒更有可能凸显其各种平台对广告商和用户的重要性,而不是对公司产生负面影响。的投资者 $Facebook(FB.US$ 应该记住,先前具有财务后果的争议并没有永久损害公司的收入或收益。虽然 $Facebook(FB.US$ 由于存在一系列争议,短期内可能会继续承受压力,目前其长期估值似乎并不过高。只要 $Facebook(FB.US$ 可以采取果断行动来管理其日益严重的麻烦,保护其市场份额并扩大其新的创新产品,但担心其今年最严重的抛售的理由就更少了。尽管这家社交媒体巨头容易受到商业不利因素的影响,但那些仍然对这家社交媒体巨头的长期增长潜力充满信心的人可能会发现,这种急剧下跌为其未来的上行空间提供了买入机会。

随着债券收益率的上升,科技股受到的打击尤其严重(许多股处于修正区间)。收益率上升通常表示投资者将来会看到通货膨胀和强劲的经济需求。
美联储证实,它可能很快就会开始减少债券购买量,这可能会降低债券价格并提高其收益率。较高的债券收益率会降低未来利润的价值,而快速增长的科技股多年来一直在寻求丰厚的利润。
从技术上讲,修正是指跌幅度为10%或以上。我认为其中一些科技股尚未触底...
我目前关注清单中的科技股:
$DocuSign(DOCU.US$
$Adobe(ADBE.US$
$CrowdStrike(CRWD.US$
$苹果(AAPL.US$
$SoFi Technologies(SOFI.US$
$谷歌-A(GOOGL.US$
$亚马逊(AMZN.US$
$台积电(TSM.US$
$SEMrush(SEMR.US$
$Fiverr International(FVRR.US$
$Facebook(FB.US$
$Spotify Technology(SPOT.US$
$思科(CSCO.US$
$Splunk(SPLK.US$
$Cloudflare(NET.US$
$Facebook(FB.US$是 2021 年 10 月 4 日最大的输家,因为它正在应对大规模停电。
我个人认为,(一次性)七小时的全球停电不会对以下方面产生任何长期影响 $Facebook(FB.US$网络效应。Facebook是一家快速增长且利润丰厚的公司。而且,基于其强劲的基本面和估值,它无疑看起来很有吸引力。

History of blockchain Technology in three steps:
- It was initially developed in 1991 as a sort of digital timestamp. Early innovators saw this function almost as a “notary” function. There could be no backdating or tampering with data utilizing the early blockchain technology.
- For almost two decades nobody really cared.
- 2009 “Satoshi Nakamoto” introduces BTC.
What is blockchain Technology?
Blockchain is a form of “Distributed Ledger.” I’ll break it down with an image so its easier to understand. Each “block” has three basic parts to it. The “data”, the “hash” and the “hash” of the previous “block”.
Data: This differs depending on the function. In something like BTC we have the sender, the receive and how many coins moved.
Hash: Think of the Hash as a unique ID or fingerprint. Changing anything about the block changes the hash.
Hash of Previous Block: That is exactly what it sounds like. A ledger containing the unique ID/fingerprint of the block before it in the chain.
You’ll notice the first block has no previous hash number. That is because it is the first block in the chain. It is known as the “Genesis Block”, the beginning.
Why is Blockchain Technology so difficult to tamper with?
A modern computer could calculate hundreds of thousands of hash/second. In theory it would be easy to tamper with a single block and then change the hash number of the preceding blocks so they would match.
A concept called “proof of work” slows down this process to prevent computing and changing previous hashes. Currently it takes about 10 minutes to generate the hashcash proofs of work to mine BTC. This means that if someone were to TRY and tamper with a block they would need to change EVERY block before that as well to hide the discrepancy and receive P2P validation.
At 10mins/block it simply isn’t possible.
Blockchain technology is built utilizing a peer-to-peer verification process. This means each when a new block is discovered it is sent to everyone on the network and each node will independently verify the correctness of the block. In the simplest terms every node executes a consensus protocol to verify the addition of the block. ALL OF THEM. This also removes the need for centralization. (ie decentralization)
Any block that has been tampered with will be rejected by the nodes.
In order to effectively tamper with the blockchain and be validated on the P2P network someone would have to:
1) Tamper with ALL the blocks on the chain. (Remember the hash of the previous block)
2) Redo all the POW.
3) Somehow take control of greater that 50% of the P2P network.

根据 脸书网站,“Facebook的使命是赋予人们建立社区的力量,拉近世界的距离。人们使用Facebook与朋友和家人保持联系,发现世界上正在发生的事情,分享和表达对他们来说重要的事情。“
所以,任何使用的人 $Facebook(FB.US$ 他们应该有权分享和表达对他们来说重要的事情,对吧?
如果用户无法分享和表达自己的观点,那么Facebook的使命就会失败,对吧?
暴跌很可能是由于其他原因造成的,例如即将加息。

$Facebook(FB.US$ 在此期间,由于市场情绪不佳,价格可能会下跌,就像其他科技股一样。更糟糕的是,它现在面临着许多问题,包括最近在自己的whatsapp和Instagram服务上遇到的问题。但是现在这个问题已经解决了。我还觉得 $Facebook(FB.US$ 是一项不错的投资,因为它可以长期持续增长。

自3月份以来,大盘股的质量领先地位预示着增长减速和财务状况的紧缩。美联储确实预计缩减计划将于今年开始。令人惊讶的是,它预计将在2022年年中之前以如此快的速度完成缩减规模。这比市场预期的要早了大约四分之一,增加了22年下半年加息的可能性,这显然是一种鹰派转变。较高的实际利率应意味着较低的股票价格。
即使整个股票市场走低,这也意味着价值超过增长。考虑到大多数投资者的定位,这给投资环境带来了双重困难。今年标普500指数实质性调整的最有力抵消因素是散户投资者极具弹性的逢低买入心态,这种策略现在正受到挑战。
在恒大下跌和反弹之后,股市探低并跌破了之前的低点,这是逢低买入首次没有奏效,同时违反了重要的技术支撑。投资服务而不是商品,本季度效果会更好。半导体和

在华尔街,十月通常是一个阴森森的月份。众所周知,股票曾在1929年、1987年10月以及最近一次暴跌。许多风险仍然存在,但股票前景仍然乐观。
“第四季度——比如体育赛事或百老汇戏剧的结束——才是这部戏的所在地。” 尽管如此,Navellier希望今年市场和整个经济通常的季节性利好风将提振股市。
股票往往不仅在10月份稳步上涨,而且在第四季度的剩余时间里也是如此。假日购物季的消费者支出激增,企业通常希望在年度预算用完之前增加投资。
