大卫莱恩(David Ryan)和马克米勒维尼(Mark Minervini)均出现在杰森施瓦格的《市场奇才》这本书里面,笔者认为这两位美国成功的交易员/投资者实际上对中小规模投资者的借鉴意义更大,因此翻译这两位成功投资者的采访文稿,以飨读者。读者可以在本文看到成功交易员的相同和不同点,得到启发。
大卫莱恩(David Ryan)很早就对股票感兴趣,16岁就订阅了投资周刊,并多次参加由威廉欧奈尔以及其他专家举办的投资研讨会。大学时代,大卫就几乎读遍所有投资书籍。威廉欧奈尔是大卫莱恩的偶像。大学毕业后,大卫决定到欧奈尔的公司工作,甚至不要薪水。短短四年,凭借其卓越的投资业绩成为欧奈尔公司年轻的副总和最具盛名的基金管理人。大卫参加了1985年的全美投资大赛,以161%的收益率夺冠。1986年参赛,160%的收益率获得亚军。1987年大卫再度参赛,并再以三位数的投资回报夺冠,三年累计投资报酬率达到1379%
马克米勒维尼(MarkMinervini)在华尔街奋战三十年,也是最成功的投资者之一。马克在1997年以155%的收益率获得了全美投资大赛的冠军。马克运用自己的策略,五年半的时间,年化收益220%,并且只有一个季度亏损。一个10万的账户最终变成300万。
对话大卫莱恩。
问:大卫,你有什么日常习惯来保证你工作状态很清醒?你的早晨是什么样的?有哪三件事情是你要做的来准备开盘?
答:我和大部分交易者不同,我会阅读圣经。浏览一遍在圣经里面的价值观和原则,能让我消除在市场做出糟糕决策的情绪。比如圣经上讲:贫穷和羞耻会降临忽略规矩的人。如果你不用纪律性的交易模式来应对市场,你就很难进步。然后我会浏览期货指数和可能影响我持仓的新闻。我也会把计划交易的股票记录下来。
问:大卫,你优先强调哪种分析:技术分析还是基本面分析?你从何处着眼?
答:大部分时间我会从技术面入手。一旦我发现一只个股走势强劲,我会去发现基本面的特征。一个好股票应当两手都硬。大波动通常因为公司大的盈利变动而来。如果一家公司走势强劲但是盈利增速不过硬,通常都走不远。
问:大卫,你如何理解图表来让你做正确的决定?你知道,每个投资者当持仓后,都倾向于对图表走势作出有利于自己持仓方向的偏见理解。你对图表交易者有什么建议?你是如何识别图表并摒弃内心的噪音。
答:你必须仔细分析股票走势的量价关系。最好的学习办法就是去研究历史上大股的走势特点。我刚开始的时候,常常几个小时盯着历史大飚股的日线和周线图看,确保这样的走势印在我脑海里面,让我条件反射般的识别什么是好的股价启动特点。我通常研究18个月的走势,股票是如何启动的,如何在走势中间持续的,然后如何冲顶的。每个阶段,股票走势的量价关系如何。交易员的工作就是去确认识别这些走势阶段。这样的学习可以通过研究历史大飚股来完成。
问:大卫,你和马克都以三位数的收益和低回撤赢得全美投资比赛冠军,你认为你和他有什么相同点让你们的投资业绩如此出色?
答:我和马克的风格好像是类似的。我和他常常锁定同样的股票,和相似的买点,而且我和他止损都很快。马克做交易非常规矩,严格执行他的策略。其实,在市场中成功的关键就是纪律性,而不取决于你的系统到底怎么样。运用系统化策略化交易方式并且纪律般地执行,可以消除买卖的情绪影响。
问:为取得一致性优异的交易成绩,你认为普通投资者面临的最大问题是什么?是纪律性,专注度还是合理的仓位控制亦或是其他?
答:纪律性、时间和努力工作是关键。对投资者最大的挑战是执行,并且要花时间。我花了两年时间才完全掌握CANSLIM模型并且为欧奈尔工作。有自己的系统之前会不断犯错,很多人不能直面犯错。如果你花时间精力来研究过去的飚股,并从你的错误中学习,并且变得更加纪律性,你会取得伟大的成功。
:对于一些刚刚开始交易的菜鸟,结合你的多年经验,你给他们的第一个建议是什么?对于一个刚刚开始的交易员,你认为最重要的原则是什么?
答:成功的第一重要原则是你要喜欢你做的事情。不成功的时候很艰难,因为你要找到赢的一条路。你要坚持下去,哪怕别人都放弃,你要有充分的成功渴望。
 
对话马克米勒维尼
问:马克,请告诉我们作为一个职业投资者的心理状态。是什么让你每天干劲十足,并且自我激励。
答:从我个人而言,我认为我的动力就像迈克尔乔丹每天都要训练一样。对这项竞技的爱,对交易的激情。你知道多少人能做自己讨厌的事情能成功的?
问:你开仓的最大头寸是多少?你允许单一仓位最多亏损多少?
答:单一个股我不喜欢超过25%,我通常持仓数量不会超过10-12个。我想要集中仓位到最好的股票上,我不喜欢分散持仓。我仔细筛选了解我持仓的基本面和技术面。当我捕捉到一个成功个股,我就会想扩大盈利,让这次交易对我整体业绩帮助极大。
问:多大程度上,你认为投资是科学和数学,多大程度是艺术?
答:我认为这与玩扑克很类似。你需要知道数学原理,需要运用技巧,知道自己的风格,你的优势和弱点。那就是交易的美,不完全是科学;如果完全是科学的话,电脑会统治交易世界,交易也没啥可以探索的了。真实世界里带情绪的群众撑起了牛股的走势。交易就是结合实战分析的竞技场。
问:你多少钱起家的?什么时候开始交易的?
答:一开始我只有几千美元,后面我加到3万美元。真的花了很长时间才把账户做大,但是我一旦有几年收益很惊人,复利就让我的账户快速增长。最后我的账户增长了3400%
问:哪种方法让你的进步最快?不断试错,阅读相关书籍,寻找导师,你对新手菜鸟有什么建议?
答:我的技能在不断的尝试总结和阅读中提高。我现在推荐找一个导师来指导。
问:马克,你曾说错误是可以接受的,但是一直错误是不可接受的。犯错不可避免,但是停留在错误就是一种选择。你能结合你自己的交易经历,详细谈谈这句话吗?
答:我的意思是每个人都会犯错,这不可避免。但是,不修正错误或者最小化犯错的损失是你完全能控制的。大损失都是从小损失开始的,最后让亏损超出承受范围。你必须意识到遭受巨大损失是你的选择,而你必须控制这样的情况。
问:马克,从你多年自身的交易经验,以及辅导很多投资者的经历来看,对于新手交易员,最重要的是是什么?
答:避免亏(大)钱。哈哈,这像是在开玩笑,其实我并没有。我的意思是当你错的时候你要尽可能亏最少的钱。如果你善于这样亏钱,你已经比百分之九十的投资者强了。如果你总是在上升潜力趋势上正确买入股票,而当你买错股票时尽快止损出来,长期来看,你就会通过交易赚很多钱。
问:马克,什么是你交易生涯的高光时刻?
答:是我许多年前读到李佛摩尔的《如何交易股票》这本书时,一本很精炼的书,但是彻底启发了我的思考。
问:成功的道路上最大的障碍是什么?
答:做到100%的交易有纪律性,100%对自己的交易过程和结果负责。承担责任意味着你知道你要控制什么,并且培养自己应对各种情况的能力。
问:什么才能区分出一个成功交易员是真正具备交易能力还是因为运气所致。有什么不同,如何区分?
答:时间。运气只能短期有效。具有技艺的交易者可以一直存活于市场,而那些之前在正确时间具有正确头寸的人迟早会在错误时间进入错误头寸,而且并不知道怎么处理这种情况。就像谚语所言,“傻子和钱刚开始会幸运地在一起,不过迟早会分开”。
问:你如何确定仓位,如何设置初始止损?
答:我使用最简单的法则。我不会在单一交易上损失总资金的1.25%-2.5%。此外,我单一标的最大持仓不超过25%,单一交易止损幅度不超过8%-10%
问:当你经历低潮期的时候,你会怎么办?
答:我会收缩头寸规模,也会缩紧风险敞口。回撤越大,我越保守。情况不对,我会很快砍仓。如果一个交易开始赚钱,我会逐渐增持,扩大盈利。
问:马克,我会问同样的问题。对于初学者菜鸟,你有什么最主要的建议?
答:找到一种适合你个性和认可的投资策略,然后全身心执行这样的策略。不要试图什么都懂,而是要当一种特别办法的专家。记住,找到这样的策略会花很多时间,不要气馁。任何成就都需要努力和时间,成功不属于那些半路放弃者。

笔者通过阅读两位天才交易员的对话有如下感悟:
1.股票市场是存在长期来看盈利的办法的,只不过需要每个人探索出适合自己的办法(策略的edge到底是什么),并且坚持不懈地执行自己的系统。长此以往,专注,认真,耐心,专业,才能成功。
2.股票市场是社会上少数能够以小博大逆袭的场所,关键是要有成功的乐观信念,要全身心投入。遇到挫折不气馁沮丧,坚韧不拔,以及持续不断不问成败的付出。二级市场,兴趣是最大的老师。

唯一保护你的投资组合

 不论你投资的方法或观点如何,唯一保护你的投资组合、让其远离巨额亏损的方法就是在损失的雪球滚大之前就卖掉它。在我 30年的投资生涯中,我还没有发现更好的方法。

Here's Why Wolfspeed Stock Is Soaring Today | Short Squeeze

Here's Why Wolfspeed Stock Is Soaring Today

By James Brumley – May 2, 2025 at 1:46PM

Key Points

  • Investors are hopeful that Wolfspeed’s next CFO will be able to steer the company to a healthier capital structure.
  • The size of today’s gain, however, has more to do with newly nervous bears than changes to the company’s management team.
  • Wolfspeed is a compelling long-term (albeit speculative) investment prospect. Just count on continued volatility for at least a little while longer.

The pent-up short squeeze just needed a fresh catalyst. It got one after yesterday's close.

Shares of industrial outfit Wolfspeed (WOLF 24.44%) are ending a raucous trading week as wildly as they started it, rallying again on Friday to overcome Tuesday's sizable pullback from the prior week's explosive gains. As of 12:56 p.m. ET, the stock is up 23%, in fact, or 35% above last Friday's close.

There's a clear catalyst for today's big move, too. But, there's also (much) more to the story.

Relief on the horizon

Wolfspeed's core business is silicon carbide, used in a range of industrial applications including utility-scale power facilities, data center power supplies, HVAC equipment, and electric vehicle charging technology, just to name a few. The company's proprietary carbon-toughed silicon can handle higher heat and greater power loads than conventional silicon can, making it a particularly important material in an era marked by the efficient electrification of... well, everything.

This shift isn't proving easy or cheap for the world's small handful of silicon carbide manufacturers, though, and Wolfspeed is no exception. The company's taken on significant debt to prepare for demand that's yet to materialize as fully as hoped. As of the end of last year, in fact, the unprofitable $680 million (market cap) company is sitting on nearly $6.7 billion worth of long-term liabilities. It's taking a toll on the stock, too, if only because it's so worrisome to current and would-be investors.

And it is worrisome to be sure -- so much so that 64% of the stock's float and 41% of its total outstanding shares have been sold short, meaning lots of traders are betting the stock's price will fall rather than rise. That's a significant vote of no confidence.

Relief may be in the works, though. After Thursday's close, Wolfspeed announced that current CFO Neill Reynolds is stepping down from the position. Although not being blamed for Wolfspeed's current difficult financial position, executive chairman Thomas Werner's comment of "Neill has been an important partner as we navigate our liability-management initiatives and position Wolfspeed for its next phase" does imply that Wolfspeed recognizes something needs to change -- soon -- with the balance sheet. The market is simply celebrating this prospect.

Short squeeze underway

That being said, it would be naïve to pretend a short squeeze wasn't also a factor here, if not the biggest one.

Simply put, short-selling is the sale of shares not yet actually owned. A short-seller's intent is rather to buy that stock at a lower price in the future to cover the commitment made by such a trade. It's risky, though, since there's no price ceiling on those shares that will eventually need to be purchased to close out a short sale.

If enough gains from a heavily shorted stock -- like Wolfspeed -- cause short sellers to panic en masse, they'll buy that stock even at a high and rising price just to cut their losses before they widen any further. This buying of course puts further bullish pressure on a stock, causing even more short-sellers to make a panicked purchase, driving its price higher still. This self-fueling covering of many short positions is called a short squeeze.

That's very likely what's happening here with Wolfspeed, given the degree of its gains just since last week. Just bear in mind that short squeezes don't last forever.

Worth a well-timed shot

A prospective short squeeze isn't a reason to buy a particular stock; this one's likely already run much of its full course anyway. Expect erratic volatility in the immediate future all the same, though, as is often the case following extreme moves.

Wolfspeed is still a compelling long-term prospect, however, particularly if you can wait for a decent dip to step into it. Global Market Insights' prediction that the worldwide silicon carbide market is set to grow at an annualized pace of 34.5% through 2034 suggests there will be more than enough business for this company to grow its way out of debt. It's just going to take some time.

Technology | Square Earnings, Revenue, Key Metrics Miss In Q1. Payment Firm Lowers 2025 Guidance.

 

Square Earnings, Revenue, Key Metrics Miss In Q1. Payment Firm Lowers 2025 Guidance.

Square-parent Block (XYZ) reported first-quarter earnings, revenue and key financial metrics that missed Wall Street targets. The digital payments company lowered fiscal 2025 guidance for Square stock amid weakness in the consumer Cash App business. Block stock plunged Friday on the news.

Released after the market close on Thursday, Square earnings for the period ended March 31 were 56 cents per share on an adjusted basis, up 19% from the year-earlier period.

Also, Square said net revenue came in at $5.77 billion, down 3% from a year earlier, amid slower Bitcoin-related growth.

Wall Street analysts had predicted Block earnings of 97 cents a share on revenue of $6.19 billion.

"We expect the stock to be under significant pressure," said Jefferies analyst Trevor Williams in a report. "Gross profit missed the Q1 guide (9% versus 11%) driven by weakness in Cash App and fiscal year outlook cut  to 12%, now incorporating a 'more cautious stance' on the macro (economy)."

The Square Cash App helps individuals manage money, buy stocks and cryptocurrency, and more. If a U.S. recession hits, the relatively low income level of some of Square's customer base has been one concern.

"Management's talk around weaker Cash App spending (while other companies in the space are speaking to solid consumer trends through the end of April), sluggish Square volume, plus the inherent risk around getting more aggressive on lending were the primary sources of additional (selling) pressure," said Evercore ISI analyst Adam Frisch in a report.

At William Blair, analyst Andrew Jeffrey says Cash App is a work-in-progress.
"Low visibility to second-half Cash App gross profit growth acceleration makes Block a show-me story," he said in a report. "We are constructive on Cash App's long-term value proposition, and we believe it will drive better monetization as Block integrates offerings like Borrow and buy now, pay later. The company needs to demonstrate that Cash App can drive primary banking relationships and direct deposit is the best measure."

Square Stock: 2025 Guidance Lowered

Financial analysts also view gross profit as a key metric for Square stock. In Q1, gross profit rose 9% to $2.29 billion vs. estimates of $2.32 billion.

At TD Cowen, analyst Bryan Bergin said in a report: "A host of disappointments around Block's Q1 execution/forecasting and reduced 2025 outlook that still features a second half ramp — albeit with a shallower trajectory and with added conservatism — truly tests a positive thesis around the stock."

Cost-cutting boosted earnings before interest, taxes, depreciation and amortization, a key metric known as EBITDA. It came in at $813 million vs. estimates of $791 million.

In Q1, gross payment volume from the transactions of merchant customers rose 7% to $54.1 billion vs. estimates of $57.99 billion.

For fiscal 2025, Square lowered its gross profit guidance to $9.96 billion, marking 12% year-over-year growth, down from its earlier guidance of 15% growth.

In its core businesses, Square operates a two-sided digital payments ecosystem, with products designed for both merchant sellers and consumer buyers. San Francisco-based Block's earnings included consumer lending firm Afterpay.

Square Stock Ratings

Heading into the Block earnings report, Square stock was down about 30% in 2025.

Square stock holds an IBD Composite Rating of 61 out of a best-possible 99, according to IBD Stock Checkup. IBD's Composite Rating combines five separate proprietary ratings into one easy-to-use rating. The best growth stocks have a Composite Rating of 90 or better.

Square stock, meanwhile, holds an Accumulation/Distribution Rating of D-. The rating runs from a best-possible A+ to a worst-possible E. The rating analyzes price and volume changes in a stock over the past 13 weeks of trading.

Further, Block changed its ticker symbol to XYZ from SQ on Jan. 21.

Why Shares of Motorola Solutions Sank Today

Why Shares of Motorola Solutions Sank Today

Story by Josh Kohn-Lindquist
 • 18m • 
2 min read

 Shares of public safety technology provider Motorola Solutions (NYSE: MSI) were down 7% as of 12:45 p.m. ET on Friday.

While Motorola grew revenue by 6% and earnings per share by 13% -- easily beating analysts' expectations -- management's soft guidance for the upcoming quarter spooked the market.

A harsh reaction to Motorola's steady (as ever) results

Motorola is a leading public safety technology provider that operates through three segments: land mobile radio (LMR) communications (think of police, fire, or ambulance walkie-talkies), video security and access control, and command center solutions (911 call centers). This focus on mission-critical products makes it a steady-Eddie operator, as its solutions are unlikely to be cut from any agency's budget.

Overall, Motorola's first-quarter earnings looked great. The company's largest segment, LMR, inched sales higher by 4%, while its faster-growing video and command center units saw 11% and 10% increases, respectively.

Meanwhile, Motorola's recurring sales from software and services jumped by 9%. These sales are paramount for Motorola, as they bring higher margins than the company's hardware products, are less cyclical, and have grown to account for roughly 40% of total revenue.

However, though management reiterated guidance for 5.5% sales growth in 2025, it projected a minute increase of 4% in Q2, prompting worries about the company reaching its full-year goals.

Furthermore, management estimated tariffs could add $100 million to its costs during the year, compared to the $11 billion in sales it expects for 2025.

Ultimately, potential tariffs and 90 days of slower growth aren't what investors should focus on. Motorola remains a leader in the mission-critical public safety niche, a top-tier compounder, and a magnificent dividend growth stock.


Snap sinks more than 12% after withholding guidance, citing ad concerns

Snap sinks more than 12% after withholding guidance, citing ad concerns





Key Points
  • Snap shares fell after the social media company withheld second-quarter guidance amid an uncertain macroeconomic environment that could hit advertising.
  • The social media company grew revenues from a year ago and reported a narrower loss.
  • Other social media companies saw shares move lower, including Pinterest, Reddit and Meta.
  • Snap shares fell more than 12% Wednesday after the social media company withheld second-quarter guidance due to the uncertain macroeconomic environment.

    “While our topline revenue has continued to grow, we have experienced headwinds to start the current quarter, and we believe it is prudent to continue to balance our level of investment with realized revenue growth,” the company said Tuesday, adding that macro conditions could impact advertising demand.

    Snap’s finance chief Derek Andersen said during an earnings call that some advertisers are already seeing an impact from changes to the de minimis exemption. The loophole, which ends Friday, currently allows shipments under $800 to enter the U.S. duty-free.

    President Donald Trump’s shifting tariff plans have created an unsettling backdrop for companies this earnings season. Fears of a weakening economy have also fueled concerns that companies could ease up advertising spending, where Snap makes a key component of revenues.

    The company said ad revenues grew 9% year over year to $1.21 billion during the quarter.

  • Despite holding back on guidance, Snap reported 14% revenue growth, up from $1.19 billion a year ago to $1.36 billion. Snap’s loss also narrowed 54% to $140 million, or 8 cents per share, from about $305 million, or 19 cents, last year. The loss was due to a $70.1 million charge related to cash severance, stock-based compensation expenses and other costs associated with a 2024 restructuring.

    Snap also signaled ongoing user growth. Daily active users grew to 460 million, up from 453 million the previous quarter. The company said it hit 900 million monthly active users, up from 850 million in August, the last time Snap provided that stat. DAUs fell to 99 million from 100 million in North America during the period, but Snap says it doesn’t expect more declines this quarter.

    Many on Wall Street expect the company’s lack of visibility into the second quarter and macro backdrop to weigh on shares and adjusted price targets to account for it.

    “While [price-to-sales ratio] is nearing a historical bottom and could support stock, we reiterate our neutral rating as Snap has been pressured more than peers in prior macro downturns,” said Bank of America’s Justin Post.

    Other social media companies saw shares move lower, including Pinterest and Reddit, last down 4% and 8%, respectively. Meta fell more than 2%.
