以研究單一公司爲例,我們需要深入認識其商業模式,看清其上游、下游、競爭對手及合作機構等情況,同時也要研究其產品或服務,創辦人背景、公司文化及激勵機制等衆多領域,這樣才可以全面地對投資目標建立基礎的認識。就算買入了投資標的後,研究的過程也不代表完成,因爲從來我們也不是單純地做Buy & Hold,而是在做Buy & Homework,投後的持續研究也是必須的,因爲再好的行業或公司也會出現變化,不能以為一時的好就是長期的好
我們不是每個行業都看,也不是每個行業也能看得懂。
股神巴菲特的好拍檔芒格提過,他一般把公司分析分作三類,分別是Yes、No及Too Hard。Yes就是你看得懂,又認為是值得投資的公司,No則相反。而Too Hard就是指那些你根本看不懂的生意模式或公司,這些機會根本不存在錯過與否,因為你從第一天起也看不到,買賣均是投機,賺錢的話是運氣,虧損是活該。
