这个故事的另一个版本是:1986年微软IPO时,比尔盖茨持有约45%的股份(部分资料称上市当日一度达到48%-49%,但随后因售股稳定在约45%)。此后他长期逐步减持,持股比例逐年下降,目前个人持股已低于1%,而盖茨基金会已经完全清掉。比尔盖茨这些股份如果一直持有到现在接近1.5万亿美金,估计未来很多年都难有人望其项背。 还有一个版本是:上世纪90年代末。当时微软股价一路飙升,比尔·盖茨的财富也随之迅速膨胀。巴菲特曾给盖茨提出一个非常简单的建议:不要把全部财富押在微软一家公司上。按照巴菲特的逻辑,创始人的财富应该逐步分散到不同资产类别中,以降低风险。随后几年,盖茨开始持续减持微软股票,并将资金配置到更广泛的投资领域。 当然从数学上看,这种推算并没有明显错误。但从投资逻辑来看,开头聊的其实是一种典型的“幸存者偏差”。没有任何人能够确定微软会在未来三十年里会一直保有强势地位,即使盖茨也不例外。 这个故事告诉我们,即使创始人自己也很长期一直坚定的持有自己创立公司的股份,坚定持有远比买入卖出要难的多。 致经常卖飞拿不住的我们自己,学会和解。 Be Water!

微软,被比尔盖茨清仓了。 盖茨基金会,刚向SEC披露, 今年第一季度, 卖掉了微软股票最后770万股, 约合32亿美元。 这是他亲手创立的公司, 现在他持股的最后一点痕迹,也没了。

$RKLB 連續第二天看 $RKLB 的交易數據,週五交易日跌了-5.87%,我想知道這樣的跌幅是不是會打擊多頭的信心? 右下圖是兩年期隱含波動率,沒有顯著升高,還是處在一個相對高但不是最高的位置,財報後的波動率已經有做頭跡象。 有趣的是左上圖,這是近期的Put/Call波動率差值趨勢,在這張圖中,我們可以很清楚看到反而因為週五的跌勢,引發多頭回籠下注。 未來四個到期日的期權全數轉折向下,這樣的形態似乎代表著市場參與者短中期都全面看多的態勢,或許是認為當下的股價已經被低估到了不合理的值。 我們用右上圖(倉位變動熱力圖),可以看到05/13 and 05/14兩天略有黯淡的Call開倉,在05/15股價下跌的這一天反而有幾個色塊都呈現白熱化狀態,而且位置是145/150、170這些價外的行權價。 搭配Put/Call波動率差值轉折向負,這些新增的看漲期權倉位應該是來自買盤追價所形成,而且設定了相當的價外程度,似乎是想博取更大的槓桿。 近期期權中,以05/22到期的期權累積量較高(左下圖)。從這張圖可以看到目前最大痛點價格還在100整數關卡,而股價已經漲到124.77,目前剛好站在125美元累積看漲倉位超3000口的位置。不過考量股價的動能,我不認為這些看漲期權會形成阻礙,唯一比較可能形成阻力的是目前在150美元超過7000口的累積天量。

$RKLB 它是大漲的股票中,特別的存在。大致看過$RKLB的歷史股價走勢,從未發生過向近期這樣的90度仰角漲勢,在這種史無前例的上漲中,波動率意外地並不算高(左上黃線圖表)。 而且就在最近的四個交易日中,近期隱含波動率(右上圖)可以看到明顯回撤,股價漲勢沒有明顯下跌前,隱含波動率就率先出現回撤。 這是不是一種多頭獲利了結? 從右下的熱力圖中,可以看到05/12日開始,連續三個交易日裡,價平與淺價外看漲期權有明顯的平倉跡象(紅色方塊),其中一部分可能往更高行權價移倉,但是這一部分的開倉追價力度在最近的三個交易日,沒有比賣方力道強多少。以至於左下圖,近期Put/Call波動率差值趨勢已經從深度負值回彈,一部分期權甚至已經彈回零線以上(由Put的隱含波動率佔上風)。 我之所以一開頭說它是個特別的存在,是因為在這麼兇猛的漲勢中,多頭熱情被激發,應該會死死地讓隱含波動率與股價正向連動,產生高度正相關的形態。不曉得該判斷為,$RKLB的參與者相對理性,還是該說他們更加傾向於及早獲利離場,選擇先落袋為安。

Elon Musk reveals the brutal math behind why a single hour of his time is worth $100 million "Tesla this year will do over $100 billion in revenue, so that's $2 billion a week. If I make slightly better decisions I can affect the outcome by a billion dollars. The marginal value of a better decision can easily be in the course of an hour $100 million" "You have to look at it on a percentage basis. If you look at it in absolute terms, I would never get any sleep. I'd just keep working and work my brain hotter, trying to get as much as possible out of this meat computer"

美光科技接下来的利润表,算了一下,接下来12个月超过120b,即使10x,也应该是 1.2T market cap, 15x对应1.8T,这个让我想起来#nvda,当年也是股价不断上涨,但是由于净收入不断上涨,所以整体来看,估值并不高,美光科技有可能重演当年nvda的戏码. #MU

They say memory is cyclical… but $MU operating profits look like this. From $1.77B in Feb ’25 → projected $35.8B by May ’27(E). +1,917% total growth. 
279.6% CAGR. The AI-driven HBM/DRAM supercycle is changing everything. Micron is printing money on a scale we’ve never seen.

Elon Musk just told a story that should terrify every AI company on Earth. His son Saxon is autistic. Saxon couldn’t understand why the family went to restaurants. You can get the same food delivered. You can call your friends over. You can eat better at home for half the price. So why go? Musk: “He had an epiphany and said, ‘Oh, the reason people go to restaurants is to hang out with strangers.’” A kid who takes the world literally just decoded something the rest of us never thought to question. We like being around people we’ll never know. Look at what we already built. Delivery apps so you never wait in line. Remote work so you never share an office. Self-checkout so you never talk to a cashier. Every innovation of the last 20 years was a bet against human proximity. Every one paid off. Until it didn’t. Loneliness is now a public health emergency. Depression has doubled since the smartphone. The average American has fewer close friends than any generation in history. We didn’t remove friction. We removed the thing friction was hiding. Now look at what’s coming. AI agents that handle your emails. AI companions that replace your conversations. AI assistants that make every human interaction optional. Same playbook. Same bet. Except this time we’re not engineering out strangers. We’re engineering out humans entirely. The coffee shop where nobody knows your name. The subway where no one speaks. The restaurant where you’ll never see that couple again. Those aren’t failed connections. They’re the background radiation of belonging. We don’t just need people who know us. We need to exist in rooms full of people who don’t. That’s what a kid understood at a dinner table that billion-dollar companies still can’t grasp in a boardroom. We spent 20 years building a world you never have to show up to. AI is about to finish the job. And nothing it builds will ever replicate sitting in a room full of strangers and not feeling alone.

Churchill and Jung understood something modern psychology forgets: Depression feeds on abstraction. It weakens when your hands touch something real. Here are 7 cheat codes to shift your nervous system from depression into momentum: 1. Use your hands to build something.

Absolutely crazy to see the S&P500 outperforming Berkshire Hathaway over the last 20 years. Warren Buffett was one of the best investors in the world and got beat by a simple index fund.

Is $DRAM ETF a good pick? The ETF $DRAM has been formed recently and has already made quite a name. Diving deeper into it however, there are two things that make me stick to individual stocks rather than buying $DRAM: 1. $SNDK has a weighting of only 4.81% in the ETF, in my eyes $SNDK deserves a bigger weighting. I presume this weighting is mostly based on market cap though. 2. $STX and $WDC are both HDD stocks and poised to profit from the AI boom. However, both stocks have already gone a structural repricing to higher multiples, in the range of 25-28x FY2027 earnings. These stocks are definitely not bad, but the real risk/reward asymmetry is in $SNDK, $MU, SK Hynix and Samsung, which are yet to undergo a structural repricing to higher multiples. Overall, $DRAM is a solid ETF and a good pick, but I would opt to pick individual stocks if you want to properly optimize your risk/reward ratio. From my point of view, the risk/reward ratio of memory stocks is much better than HDD stocks. Not financial advice.

Brad@BradleyKellard·
5 years ago, John McAfee gave his last interview to a college kid. He said: "Don't you understand? You have just sold yourself into slavery." The kid was talking about getting a degree, finding a job, paying off debt. McAfee wasn't sympathetic. He was horrified. Here's everything he said: You're Not Free. You're Just Comfortable. McAfee's biggest argument was simple: Most people don't live. They comply. You go to college → get a job → commute every day → sit in a windowless office for 40 years → retire. Not because you love it. Because you're afraid of what happens if you stop. That fear, he said, is the real prison. He called it modern scrip. In the 1800s, coal mine workers were paid in fake company currency, only spendable at the company store, at company prices. Workers earned. The company owned everything their earnings could touch. "The US dollar is just scrip from a bigger company called the government." You earn it. They take 25%. They can print trillions more overnight and silently shrink everything you've saved. And you can do nothing. Your Mind Is Lying To You McAfee made a distinction that runs through the entire interview: Your heart and your mind are not the same thing. The mind calculates. It says: get the degree, join the firm, plan for the future, anticipate consequences. The heart doesn't work that way. "It doesn't matter if your heart says I just want to make shoes, then make shoes. I just want to wander and see the world, then see the world." Someone pushed back: but what about money? His answer: "You have half a brain and two hands. You'll figure it out." He used falling in love as proof. When you fall in love, did you stop and calculate consequences? No. You just followed it. That's the heart. The mind inflates consequences. The heart finds a way. On Being a Fugitive and Feeling More Free Than Anyone McAfee had been arrested 21 times across 11 countries. The student asked: doesn't that weigh on you? McAfee's response: "There's nobody more 'in' than Janice and I. You folks are on the outside looking in." He referenced Thoreau, jailed for civil disobedience. A friend visited and asked: "What are you doing in there?" Thoreau looked back and said: "What are you doing out there?" McAfee's point: Freedom isn't about your circumstances. It's about whether you're living your values or someone else's. The people obeying laws they never agreed to, working jobs they don't love, staying afraid. They're the ones who are trapped. The walls are just invisible. The Two-Party System Is a Trick McAfee ran for president twice. He was clear. He wasn't interested in politics. He was interested in exposing it. "The CIA calls presidents 'transients' because that's what they are." Real power lives with the unelected permanent class. Career bureaucrats. Intelligence agencies. People no election can remove. Presidents come and go. The machine doesn't move. And the two-party system? It's a division engine. Gun control. Immigration. Every hot-button issue. McAfee called these false divisions, installed into your mind to keep you fighting each other while the system runs untouched. "Not a single hair on your head was affected by their change in power." Crypto Is the Exit Door This was his real prescription. Every currency in history requires you to trust someone. The government. The Fed. The bank. And whoever you trust controls you. Crypto breaks this for the first time. Permissionless: send money anywhere, no approval needed Trustless: math guarantees honesty, no middleman required Fixed supply: no one can print more and quietly rob you McAfee and Janice had no bank accounts, no phones, and were paid entirely in cryptocurrency. To him, this wasn't extreme. It was logical. "The phone is a spy device. The bank is a control mechanism. If you have neither, you're very difficult to own." On Happiness, From a Man Who'd Just Left a Dominican Jail The final question: Are you happy? "I'm as happy as anyone can ever be. And every day I get happier." He'd just gotten out of a Dominican Republic prison. His wife heard him laughing through the night while they were locked up. "If your heart leads you into jail, be happy there. Things will work out. I promise you." His formula was brutally simple: Accept where you are. Follow your heart. Stop trying to plan your way into safety. John McAfee died in a Spanish prison in June 2021. He was found dead the same day Spain approved his extradition to the US. He had tweeted months before: "If I suicide myself, I didn't." Whether you believe the official story or not, one thing is hard to ignore. The man who spent his entire life refusing to be owned by any system, died inside one. Make of that what you will. But the question he kept asking in this interview deserves an honest answer from each of us: Are you living your life, or are you just managing your fear?
