1. 標的: APPS SQ CRWD
2. 分類:多
3. 分析/正文:
標題加上CRWD方便搜尋,整合成一篇文。前面關於APPS和SQ文很多想搜的可以去搜。
現在這三支我部位都在21-25%,手上現金11%,不打算再賣來提升現金水位。
CRWD
這幾天美國有個大事件是SolarWinds,一家做IT sys admin軟體的公司被駭,手法相當精妙而且種後門到下手時間極長,疑似是俄國國家級駭客。內容我不多講,但幾乎美國ㄧ半聯邦政府組織受影響。
Solar Winds除了公布怎麼被駭以外作了啥?把CrowdStrike EDR推送給旗下全部,一萬八千個客戶。我估了一下,這個可能每季會幫CRWD加$10-100M營收。下季有可能會看到成長率破百的神奇數字。

CRWD他們的雲端第一小EDR系統會打爆所有的傳統企業資安公司。我認為隨時可以買。
有人問ZS,據我所知他們著重的點是ZeroTrust跟CRWD其實不是完全競爭者。傳統的防毒像Symantec,McAfee或一些公司像Cylance才是。
關於價格錨定(anchoring)
最近這三隻都爆漲,這個效應變得相當明顯,想寫ㄧ下。
我認為追求高投報率的最大殺手之一就是錨定。最近在讀Daniel Kahneman的經典Thinking Fast and Slow,其中關於錨定的敘述講到不管是什麼問題或大小,第一個被拋出來的數字,都有40%的錨定效果。
書中的例子可以上網查,你問人一棵樹最多能長到多高,分兩組A、B。先問是非題,再問個人估計
第一題
A:「你覺得是超過1000英呎嗎?
B:「你覺得是超過100英呎嗎?」
第二題
「你覺得最高是多高?」
結過A組的平均估計比B整整高40%
在投資時這現象反應出來的是:當你手上持有成本低時,會錨定在低價而不敢在高價加碼。APPS買在35的人會覺得現價57太高不敢加碼。還未進場的人反而沒這個問題。
當然加碼可以無腦定期定額加(回測證實通常是最好做法)也可以等相對低點安心加(相對低點不代表會低於現價,通常輸無腦定期定額加,但對ㄧ部分人來說抱得安心),這不是重點
重點是要「看現在」而不要被過往價格束縛。如果A還能上漲一倍,B股看起來便宜但只有50%,則買A才是正確的選擇。
能漲到哪沒人知道,所以上面也是實際操作時無法應用。但我們能挑好公司而不是好股票。
非理財建議僅供參考。
附錄:當初APPS 42掉到26時大家心情複雜,現在回頭看可能會覺得不知道在複雜什麼。通通都是買點。
