[唔揸飛機,咪揸鑊鏟]都係隨機應變要冷靜啫,飛機師炒股,你估掂唔掂?
TLDR:邪惡華爾街真人實驗,搵班飛機師嚟,教炒股票。其他素人做對照實驗,最後邊組贏?
FT原文:Pilots swap the cockpit for trading screens(https://bityl.co/40Uw)
1. 作為一個麻撚煩嘅學霸(係喎,又要講),細個時聽到話性格緊過能力,當然唔多高興。不過越大就越信呢樣嘢。同樣地,唔少人認為金融工作(*),特別係炒賣,係唔使乜hard knowledge嘅。畢竟唔少人心目中,唔係升就跌,同賭百家樂睇路捉莊閒冇乜分別(所以賭百家樂咪輸仆街,何生可以咁多女人,金沙銀河可以做恒指成份股咯)
2. 的確,炒股票,似乎唔係咩學術研究。大可以盲拳打死老師傅(你睇丁蟹?)。咁當然點落盤點睇價之類都要知,但呢類硬知識好快學到。勁人往往做唔同工種都勁,亦因為咁你見鬼佬啲I Bank員工好多都唔係讀商學院出身。至於咩「香港HR短視埋沒我才華」之類就另行討論
3. 掉轉,有唔少其他行業人員嘅特質,可能可以幫到金融工作。例如軍人。王雅麗寫過嘅例子:有軍人退役後去見工,指自己「過去兩年,每一分鐘都有可能是最後一分鐘。你說我能抵受壓力嗎?」—的確,如果trading 要求嘅係(***)要受得住壓力,咁軍人肯定受得住。同樣地,我估醫生都可以係好嘅trader,反正醫生本身好多係學霸。你睇The Big Short,Michael Burry(Christian Bale)未做對沖基金之前,根本就係醫生。真正MD,唔係周兆祥之類。
4. 咁,不如試下飛機師?揸飛機同揸鑊鏟,應該都差不多啦。真喎,煩惱似春風秋雨,季節又似人生(識唱一齊唱!)。揸飛機要諗定點應對突發情況,氣流暴風,揸鑊鏟一樣,忽然南海打仗又點,忽然侵侵死咁又點。原理差不多。
5. 另外,揸飛機要睇天氣睇地形睇呢樣睇嗰樣,揸鑊鏟一樣。計下入幾多油,有事飛去邊度緊急降落,定下咩位止蝕,原理好似差不多。
6. 不過,個難度係,飛機師雖則巴閉,但一般嚟講你行入去大行叫人畀你做Trader,都係冇咁易嘅。醫生Michael Burry點入行做基金經理架呢?好簡單,佢係自己搞個對沖基金嘅!(有錢到一個點)
7. 幸好,今次疫情就帶嚟機會啦。邪惡嘅華爾街(其實係倫敦),就有人諗,喂,不如搵幾件機師嚟玩下。畀啲基本訓練佢地,然後落場炒。最重要係,搵個control group(留意,都係外行人,但唔係機師,咁先公平)。睇下係咪真係揸飛機掂揸鑊鏟都掂—反正啲機師都冇工開架啦!
8. 是真的,有人真係做呢個實驗。訓練完班機師,畀錢佢地炒。贏嘅機師分六成,輸嘅唔使上身。嘩。當然金額有限,實驗啫。同埋啲交易都要阿頭批。咁由於啲機師真係冇工開,甚至畀人炒埋,就有人願意試下。分錢事少,有機會真係轉行事大。
9. 班機師話,好玩,幾開心,想諗下轉行。真係呀,揸飛機同揸鑊鏟,真係差不多,都係要受壓力啦,迅速做決定啦,消化一大堆資料啦。真係差不多。
10. Except it isn’t
11. 結果就係,班機師,夾埋係輸錢嘅—而大市係升的。嚴重跑輸。更不堪嘅係,Control Group嘅人,就75%都有錢賺。大家都係金融外行,但非機師,炒股票勁過飛機師
12. 點解呢點解呢?實驗搞手試下搵答案。原因其實好簡單,因為「揸飛機真係唔同揸鑊鏟」。
13. 好簡單,投資都有所謂Losers’ game 嘅比喻,讀CFA一定知(你唔知咪因為你冇讀)。Losers’ game唔係玩嘅都係北京Loser,而係話,主動靠技術得分,定係等對手出錯。職業球手打網球就係Winners’ game,outclass對手。大家業餘打網球就係Losers’ game,啲友係自己打出界,跣低,發球雙錯誤,送分畀人地。以最好策略係保守啲,等對手犯錯。
14. 飛機師呢?如果你係萊特兄弟年代,就係Winners’ game,神乎奇技,開戰鬥機咁。但現代民航機?當然係Losers’ game,穩陣,冇人叫你要轉體三週半,最緊要平安,唔好死人,唔好炒咗架機
15. 所以,民航機機師一定係保守的。但拎去炒股票,就未必係好事。特別留意,個安排係贏咗機師拎六成,輸咗唔使上身(原文寫protection from any losses,我係咁理解)—咁更加應該take risk
16. 但見到機師性格使然,係唔會咁冒進的。見到佢地普遍持貨嘅時間,係長過普通人嘅,亦唔多肯斬纜。機師慢慢先發現,揸飛機出事就死人,但揸鑊鏟出事輸錢啫,唔使死人,「仲好多時唔係自己錢」
17. 實驗主持人都仲係樂觀嘅,覺得再教育下應該大有可為。但同時亦都發現,似乎機師唔應該就咁炒股票,「可能炒啲技術含量高啲嘅衍生產品好啲」—此話不假,埃汾其實都有讀Derivative (唔係你Degree 買本John Hull嗰啲,至少都自己寫個程式去解partial differential equation),入面啲東西,甚麼PDE呀 Heat Equation 呀Time Mesh呀,其實係工程嘢,同飛機師啲流體力學有啲共通。
18. 又,篇文冇講,但埃汾提議。民航機機師咁保守,應該搵開戰鬥機嘅空軍嚟炒嘛,應該幾有趣(其實其他行一早試過搵軍人,聽講不錯的說,問題係好多軍人就真係唔係點肯讀書)
(*)實情金融工作有好撚多種,你做會計當然要hard knowledge,做分析員都要。做Quant做Derivative 肯定要,但Trader可能真係唔多使。
(**)實情點先可以成為一個好trader,都仲未有定論。但有趣地,似乎普遍女性表現係好過男性嘅,因為男性啲睪丸酮過剩,ego大過春袋,衰衝動。所以有基金專請老嘢(已冇晒火),女人,甚至要食藥。另文再講

heat equation 在 Yo Yossavadee Facebook 的最讚貼文
I believe in love. I believe in hard times and love winning. I believe marriage is hard. I believe people make mistakes. I believe people can want two things at once. I believe people are selfish and generous at the same time.
I believe that everything happens for a reason. People change so that you can learn to let go, things go wrong so that you appreciate them when they're right, you believe lies so you eventually learn to trust no one but yourself,
I believe in lust and sex and romance. I don't want everything to add up to some perfect equation. I want someone to go crazy out of his mind for me. I want to feel passion and heat and sweat and madness. I want valenties and cupids and all of that crap. I want it all. I believe that you can be surprised by life. I believe in happy endings ❤️ Life begins with belief! #liveyourlifetothefullest
