<p>华尔街充满了众所周知的资金经理，他们能够发现好的交易。然而，没有哪位基金经理能像 <strong>伯克希尔哈撒韦</strong>（BRK.A 0.07%）（BRK.B -0.07%）的亿万富翁首席执行官沃伦·巴菲特那样吸引专业和普通投资者的注意。</p>
<p>奥马哈的先知的名声直接反映了他长期超越基准 <strong>标准普尔 500</strong> 的表现。尽管标准普尔 500 在六十年间提供了近 43,000% 的可观总回报（包括股息），巴菲特却使其公司的 A 类股票（BRK.A）实现了近 5,800,000% 的累计回报！</p>
<p>在 60 年中近 20% 的年化回报率使一些投资者开始模仿巴菲特的买卖活动，这可以通过 13F 表格相对容易地完成。</p>

<p>13F 是一个要求在季度结束后不超过 45 个日历天内提交的文件（对于 6 月结束的季度，截止日期为 8 月 14 日），适用于管理资产至少为 1 亿美元的机构投资者。它为投资者提供了华尔街最聪明的资金经理正在买卖哪些股票的快照。</p>
<p>伯克希尔的第二季度 13F 显示，其亿万富翁老板再次出售其第一大投资持股 <strong>苹果</strong>（AAPL -0.54%）的股份。同时，他在一个行业领先的公司中加大了投资，该公司的股票自首次公开募股以来已经飙升了近 48,000%（包括股息），这是连续第四个季度。</p>
<h2>亿万富翁沃伦·巴菲特自 2023 年中以来已出售超过 6.35 亿股苹果股票</h2>
<p>截至 2023 年中，伯克希尔哈撒韦在苹果的持股为 915,560,382 股，接近巴菲特管理的投资组合价值的 50%。</p>
<p>苹果符合奥马哈先知的所有标准：</p>
<ul>
<li>其客户群对品牌高度忠诚，这意味着他们愿意定期升级设备，并且对价格相对不敏感。虽然巴菲特可能对 iPhone 的工作原理了解不多，但他对消费者购买习惯有着深刻的理解。</li>
<li>它拥有一个值得信赖的管理团队，由首席执行官蒂姆·库克领导。多年来，库克一直在监督公司向服务型模式的稳步过渡。订阅服务将进一步增强品牌忠诚度，并对公司的运营利润率产生积极的长期影响。</li>
<li>它拥有全球最大的资本回报计划。自 2013 年启动股票回购计划以来，苹果已花费 7963 亿美元回购股票。反过来，其流通股数量减少了 43.6%，这无疑提升了每股收益（EPS）。</li>
</ul>
<p>尽管符合所有标准，巴菲特在过去两年（截至 6 月 30 日）出售了 635,560,382 股苹果股票，代表了伯克希尔在苹果的 69% 持仓。这包括在最近一个季度再出售的 2000 万股。</p>
<p>部分出售活动可能仅仅代表简单的获利了结。在 2024 年 5 月的伯克希尔哈撒韦年度股东大会上，巴菲特表示，投资者会欣赏看到他的公司在企业所得税率历史低位时锁定收益。他在做这些评论时特别提到了苹果。</p>
<p>但也有可能是一些更不利的因素导致了苹果股票的持续抛售。</p>
<p>可以说，苹果面临的最大问题是其增长引擎在三年内停滞。尽管服务部门的销售持续以低双位数百分比增长，但实体设备的销售直到最近一直处于挣扎状态。</p>
<p>当巴菲特在 2016 年第一季度开始购买苹果股票时，其股票的 12 个月滚动（TTM）每股收益倍数通常在 10 到 15 之间。截至 8 月 15 日收盘，苹果的 TTM 收益倍数约为 35。伯克希尔的亿万富翁老板是一位重视价值的投资者，当实体设备销售没有增长时，拥有 35 倍每股收益的苹果股票变得难以合理化。这可能解释了为什么巴菲特对伯克希尔哈撒韦的第一大持股如此慷慨地按下了出售按钮。</p>

<h2>这只近 48,000% 的赢家已被伯克希尔的亿万富翁老板连续四个季度购买</h2>
<p>最近，出售股票已成为奥马哈先知的常态。根据伯克希尔哈撒韦的季度运营结果，他已经连续 11 个季度出售的股票超过购买的股票，总额达到 1774 亿美元。苹果在这 1774 亿美元以上的净出售活动中占据了重要部分。</p>
<p>但在过去一年中也有一些零星的购买活动。更具体地说，伯克希尔的亿万富翁首席执行官连续四个季度购买了游泳池用品和相关设备分销商 <strong>Pool Corp.</strong>（POOL -2.05%）：</p>
<ul>
<li><strong>2024 年第三季度</strong>：购买 404,057 股</li>
<li><strong>2024 年第四季度</strong>：购买 194,632 股</li>
<li><strong>2025 年第一季度</strong>：购买 865,311 股</li>
<li><strong>2025 年第二季度</strong>：购买 1,994,885 股（总持股 3,458,885 股）</li>
</ul>
<p>在连续两个季度将伯克希尔在 Pool Corp.的持股翻倍后，巴菲特的公司现在持有 9.3% 的股份。</p>
<p>Pool Corp. 体现了巴菲特的长期理念。他将收购的资产和伯克希尔的 2950 亿美元投资组合进行了调整，以充分利用经济周期的非线性特征。巴菲特明白衰退和股市修正是不可避免的，但他认识到美国经济在扩张阶段所花费的时间相对于收缩阶段来说是极不成比例的。与游泳池安装和维护相关的公司在这些漫长的扩张期中将逻辑上受益。</p>
<p>在这一点上，Pool Corp. 从经常性收入中产生了相当大比例的收入。一旦房主安装了游泳池，来自房主和游泳池技术人员的维护或修理产品的需求往往相对稳定。</p>
<p>伯克希尔的亿万富翁投资者可能也是 Pool 资本回报计划的支持者。尽管没有什么能与苹果相提并论，但 Pool 正在为其股东分配相当大比例的现金。在 2025 年前六个月，它在回购股票和分配股息支付方面的支出超过了 2.52 亿美元。</p>
<p>巴菲特的新宠 Pool Corp. 唯一的缺点是其股票并不便宜。它的交易价格接近未来一年收益的 28 倍，这比基准标准普尔 500 指数的未来市盈率要高。虽然作为行业领导者，拥有丰厚的经常性收入和强劲的资本回报计划确实值得更高的估值溢价，但尚不清楚投资者通过逆势而游能获得多少额外的上涨空间。</p>

<div class="lb-trans"><p>苹果符合奥马哈先知的所有标准：</p>
</div><ul>
<li>Its customer base is highly loyal to the brand, which means they're willing upgrade their devices regularly and are relatively price agnostic. While Buffett may not understand much about how iPhones work, he has a solid understanding of consumer buying habits.</li>
<li>It has a trusted management team, led by CEO Tim Cook. For years, Cook has been overseeing his company's steady transition toward a services-based model. Subscriptions will only enhance brand loyalty and should have a positive long-term impact on the company's operating margin.</li>
<li>It sports the biggest capital-return program on the planet. Since initiating a share repurchase program in 2013, Apple has spent $796.3 billion to buy back its stock. In turn, its outstanding share count has declined by 43.6%, which has provided an undeniable boost to its earnings per share (EPS).</li>

<div class="lb-trans"><ul>

</ul>
</div><p>Despite checking all the right boxes, Buffett has sold 635,560,382 shares of Apple, representing 69% of Berkshire's position, over the trailing-two-year period (ended June 30). That includes another 20 million shares during the most recent quarter.</p>

</div><p>Some of this selling activity may represent nothing more than simple profit-taking. During Berkshire Hathaway's annual shareholder meeting in May 2024, Buffett opined that investors would appreciate seeing his company lock in gains while the peak corporate income tax rate was historically low.

<div class="lb-trans"><p>但也有可能是一些更不利的因素导致了苹果股票的持续抛售。</p>

As of the closing bell on Aug. 15, Apple's TTM earnings multiple was approximately 35. Berkshire's billionaire boss is a big-time value investor, and it's becoming difficult to justify owning Apple at a multiple of 35 times EPS when its physical device sales haven't been growing. This may explain why Buffett has been liberal with sell button for Berkshire Hathaway's No. 1 holding.</p>

<div class="lb-trans"><p>在连续两个季度将伯克希尔在 Pool Corp.的持股翻倍后，巴菲特的公司现在持有 9.3% 的股份。</p>
</div><p>Pool Corp. speaks to Buffett's long-term ethos. He's angled his acquired assets and Berkshire's $295 billion investment portfolio to take full advantage of the nonlinearity of economic cycles. Buffett understands that recessions and stock market corrections are inevitable but recognizes the U.S. economy spends a disproportionate length of time expanding, relative to contracting. A company tied to pool installation and maintenance is going to logically benefit from these long-winded periods of expansion.</p>
<div class="lb-trans"><p>Pool Corp. 体现了巴菲特的长期理念。他将收购的资产和伯克希尔的 2950 亿美元投资组合进行了调整，以充分利用经济周期的非线性特征。巴菲特明白衰退和股市修正是不可避免的，但他认识到美国经济在扩张阶段所花费的时间相对于收缩阶段来说是极不成比例的。与游泳池安装和维护相关的公司在这些漫长的扩张期中将逻辑上受益。</p>
</div><p>Along these same lines, Pool Corp. generates a significant percentage of its revenue from recurring streams. Once a homeowner puts in a pool, demand for maintenance or repair products tends to be relatively steady, both from homeowners and pool technicians.</p>
<div class="lb-trans"><p>在这一点上，Pool Corp. 从经常性收入中产生了相当大比例的收入。一旦房主安装了游泳池，来自房主和游泳池技术人员的维护或修理产品的需求往往相对稳定。</p>
</div><p>Berkshire's billionaire investor is likely also a fan of Pool's capital-return program. Although nothing matches Apple, Pool is allotting a sizable percentage of cash for its shareholders. Through the first six months of 2025, it's spent north of $252 million, combined, repurchasing its stock and parsing out dividend payments.</p>
<div class="lb-trans"><p>伯克希尔的亿万富翁投资者可能也是 Pool 资本回报计划的支持者。尽管没有什么能与苹果相提并论，但 Pool 正在为其股东分配相当大比例的现金。在 2025 年前六个月，它在回购股票和分配股息支付方面的支出超过了 2.52 亿美元。</p>
</div><p>The one knock against this new-found favorite of Warren Buffett's is that Pool Corp. stock isn't exactly cheap. It's trading at nearly 28 times forward-year earnings, which is pricier than the benchmark S&amp;P 500's forward price-to-earnings (P/E) ratio. While an industry leader with bountiful recurring revenue and a hearty capital-return program does deserve a valuation premium, it's not clear how much additional upside is available for investors by swimming against the proverbial current.</p>
<div class="lb-trans"><p>巴菲特的新宠 Pool Corp. 唯一的缺点是其股票并不便宜。它的交易价格接近未来一年收益的 28 倍，这比基准标准普尔 500 指数的未来市盈率要高。虽然作为行业领导者，拥有丰厚的经常性收入和强劲的资本回报计划确实值得更高的估值溢价，但尚不清楚投资者通过逆势而游能获得多少额外的上涨空间。</p>

Billionaire Warren Buffett Sold 69% of Berkshire's Stake in Apple and Has Loaded Up on This Industry-Leading Stock for 4 Straight Quarters
