先感謝大大很多仔細的分析
有些認同也有些不完全認同
不過我覺得股版似乎要有一些更學術的討論?
先提出幾個問題
(1)台股整體本益比現在是不是真的太高(不是說個股)
根據財經M平方給出2021.03的數字是21.66
以歷史來看台股本益比約略落在15-20這個區間
不過本益比評價向來會受到市場平價的影響
譬如蘋果的本益比跟中鋼的本益比本來就會不一樣
現在這個數字是否代表高到泡沫?
2000年.com泡沫之前台股本益比可是50up
破裂後股市崩盤,本益比最低跌到14左右
接著大家搶反彈但是企業營收還沒跟上又在2002年一度爬到60幾
最後又帶來指數修正從6000多點到4000多點
此後本益比一直在15-20這個穩定區間
之後就走一個長多格局到2008金融海嘯
金融海嘯前其實本益比一直都是合理的,這完全是國外造成的系統性崩盤
崩盤後因為真的影響實體經濟巨大
即便指價跌到那麼低,當台股還在5000多點時本益比就已經高到60幾
甚至到2010年指數回到近8000點時本益比是誇張的124
這麼高的本益比有沒有帶來指數劇烈的修正?其實也還好
指數雖然有一路漲到9000後面短暫回到7000
但往後攤開來看,假設你持有大盤指數從2010-2020,這段長多格局其實能讓你吃得飽飽的
因為後面再也沒遇過像2000.2008這樣的崩盤
直到去年的疫情....
不過去年疫情V轉得實在太過快速,跌的幅度比起前兩次輕
又因為疫情帶來對電子產品的需求
帶動前所未有強勁的實體經濟成長
(2)所以這延伸出一個問題,單看本益比真的能夠預測大盤會不會崩盤嗎?
我個人的答案是不行
當然憑空創造超高的本益比要小心 但台股目前應該還沒有這樣的型態
畢竟稍微偏高的本益比是有實質營收在支持的
雖然我個人選股也是熱愛低本益比的股票
因為安全邊際較大,而且有可能因為成長+估值改變有爆炸性的收益
但也很難確定高本益比的股票未來是否就會崩跌
比起本益比
本益成長比(Price to earning growth ratio, PEG)
其實更適合用來評估成長股
當然2021賺多少2022賺多少總是有猜不准的時候
台股比較沒有財測的習慣,美股財測你就會看到這些公司財報總是跟預期有所出入
但大致上狀況不變時 好公司要馬是跟預測差不多 或者就是會超乎預期
這也是市場願意給這些公司更高本益比的原因
EPS YOY 20%, PE 20跟 EPS YOY 10%, PE 15
前者可能比後者更加便宜
在討論台股本益比時,也不要忘了去看看實際的財報數字
當然未來晶片overbooking情況突然緩解
會不會因為庫存增加,造成前端公司消化不掉財報數字難看
進而減少對供應商的下單
這當然值得觀察
但也用本益比就預期台股持續大崩盤
恐怕不太實際
(3)台股會不會繼續向下修正?
當然可能會
我前面的歷史也提到,如果你是不能承受9000-->7000的投資人
那你自己要小心手上的部位
這我無法預期
事實證明多數宣稱自己能預測短期市場發展的人多半是唬爛的
但如果你是長線投資人
回去2010年,你會選擇賣出手上的股票嗎?
何不放著享受2010-2020的行情?
(4)通膨是不是問題?升息又是不是問題?
首先如果真的比較199X年那種CPI年增率5-6%
現在的通膨真的太不膨了
在過去201X年,如果計算較不會受到炒作影響的core CPI都在2%出頭
現在短線上因為又在吵通膨
才會看到不計算食品/能源的core CPI才1.6%,而CPI卻已經2.6% (2021.03)
從歷史看來炒作結束後CPI最終會跌下來, 或core CPI漲上去趨於一致
去年很多人認為就是單純資金行情
但我認為應該兩者兼具
升息的確會導致資金回流
但是資金會回流到真正有收益的市場 或者變成現金
就過去美國升息的經驗
美國從2016升息到2020,道瓊也從20000點漲到了30000點
升息往往是短期修正的好理由
但長期股市還是跟實體經濟成長跟企業營收息息相關
如果你持有市場,或持有一家公司的股票
比起是不是有太多人來買
你應該更在乎的還是他的收益是否對得起他目前的股價
升息或許會對企業估值造成些許影響
但如果持有現金怕通膨,持有債券又怕長期輸給市場
巴菲特也說了債券未來必定是暗淡的
看看US10Y殖利率如何從1980年一路穩定的跌了40年...
我懷疑真的有人會放心購買這樣的產品...
當然我個人猜測指數型ETF的出現,其實某種程度下降了投資股市的長期風險
也會改變以前人堅持股債配置的生態
以前的建議,現在是否也能適用真的要很小心
假設未來資金畢竟是要放在股票市場的時候
通膨萬物皆漲 股票一樣會是漲的
(而且漲的更有道理,你錢放在裡面就是促進科技的進步,回饋到人類身上
跟炒作所謂的抗通膨商品不同,黃豆的價格可以上上下下
但他的價值就是拿來吃這點恐怕幾千年都不會改變的)
以上一些想法提出來討論分享
