<p>如今市场变化比以往任何时候都要快，昨天的赢家很快就可能成为今天的输家。当价格超出基本面时，交易者通常依赖技术指标和信号来指导他们的决策。动量指标如相对强弱指数（RSI）并没有预言的能力，但它们确实提供了关于股票可能走向何方以及背后有多少力量支持这一走势的线索。结合使用多种指标可以提供坚实的证据，表明下行趋势即将突破。或者，在这三只股票的情况下，上行趋势正在失去动能。</p>
<p>过去几周，科技板块一直是市场上波动性最大的部分，纳斯达克 100 指数在多个场合单日波动超过 2%。虽然波动的交易时段对日内交易者来说是有趣的，但当指数每天波动 2% 时，评估市场就变得困难。这就是技术分析发挥作用的地方。技术指标利用最近的价格数据生成关于动量变化或延续的可操作信号。通过应用技术分析，我们可以根据围绕股票的买卖活动强度，对其未来走势做出有根据的预测。</p>
<p>以下三只股票均符合特定的标准。它们在过去 12 个月中均上涨了 20% 或更多，受到各种基本面和宏观因素的推动。然而，这些股票目前显示出技术警告信号，投资者应仔细审查。</p>
<h2>Fortinet：超买峰值与内部人士卖出警告</h2>
<p>Fortinet Inc. NASDAQ: FTNT 一直是 “软件并未死去” 叙述的代表。这家市值 1060 亿美元的网络安全公司，其股票年初至今（YTD）上涨超过 80%，其中过去三个月上涨超过 70%。</p>
<p>软件行业似乎成为了代理 AI 的目标，像 iShares Expanded Tech-Software Sector ETF BATS: IGV 这样的基金在 9 月至 4 月之间损失了超过 35% 的价值。然而，Fortinet 等公司的强劲收益表明，AI 可以补充软件平台，而不是将其淘汰。Fortinet 在 2026 年第一季度的业绩超出预期，超越了收入和利润的预期，并实现了 20% 的同比（YOY）收入增长。</p>
<p>管理层还提高了全年指引，并回购了超过 8 亿美元的股票。那么，为什么这只股票会出现在 “卖出时机” 名单上呢？因为有时候，最重要的技术信号并不在图表上显示。内部人士在过去两个季度以更快的速度出售股票，包括首席执行官 Ken Xie 的 2300 万美元的出售。</p>
<p><img src="https://imageproxy.pbkrs.com/https://www.marketbeat.com/logos/articles/med_20260611133346_ftnt2026-06-1111-51-40.PNG?x-oss-process=image/auto-orient,1/interlace,1/resize,w_1440,h_1440/quality,q_95/format,jpg" alt="" width="1200" height="683" original-src="https://imageproxy.pbkrs.com/https://www.marketbeat.com/logos/articles/med_20260611133346_ftnt2026-06-1111-51-40.PNG"/></p>
<p>在过去一年中没有显著的内部人士买入，而在技术高点的内部人士卖出通常是一个警告信号。布林带的扩大表明 FTNT 股票的波动交易已成为常态，而移动平均收敛发散（MACD）指标在强劲反弹后已转为看跌。公司的长期基本面仍然看起来很有前景，但现在可能明智的是先获利了结。</p>
<h2>Amprius：负面催化剂下的技术崩溃</h2>
<p>Amprius Technologies Inc. NYSE: AMPX 缺乏 Fortinet 所拥有的强大基本面基础，这意味着其下跌可能会更加剧烈。</p>
<p>这家锂离子电池生产商的收入超出预期，其股票年初至今仍上涨超过 100%，但由于对其收入质量的担忧，反弹正在减弱。最近一份空头报告声称，该公司夸大了订单，并与与 Amprius 首席执行官相关的关联方进行未披露交易。</p>
<p>该公司在 2026 年第一季度的财报中报告了超出预期的亏损，内部人士在过去三个季度出售了 8300 万美元的股票，没有一次买入。</p>
<p><img src="https://imageproxy.pbkrs.com/https://www.marketbeat.com/logos/articles/med_20260611133407_ampx2026-06-1111-55-30.PNG?x-oss-process=image/auto-orient,1/interlace,1/resize,w_1440,h_1440/quality,q_95/format,jpg" alt="" width="1200" height="683" original-src="https://imageproxy.pbkrs.com/https://www.marketbeat.com/logos/articles/med_20260611133407_ampx2026-06-1111-55-30.PNG"/></p>
<p>AMPX 可能正朝着令人畏惧的双顶形态发展，其他信号表明乐趣已经结束。自三月中旬以来，RSI 和 MACD 均呈下行趋势，而前者在过去六周的大部分时间里处于看跌区域。AMPX 尚未盈利，空头卖家公开质疑其收入来源，因此明智的做法是避免这只股票或在可以时获利了结。</p>
<h2>AppLovin：死亡交叉掩盖基本面强劲</h2>
<p>AppLovin Corp. NASDAQ: APP 年初至今已经下跌超过 25%，尽管其在 2026 年第一季度的收入增长超过 56%，并且仍然受到分析师的好评。但尽管基本面强劲，这只股票正处于难以摆脱的熊市之中。</p>
<p>这可能看起来有悖常理，但 APP 股票可能不会反映公司的实力，直到技术形势改善。</p>
<p>三月初的死亡交叉表明，这只股票在恢复买入动能之前还有很长的路要走。</p>
<p>死亡交叉使股票跌破 50 日和 200 日移动平均线，并在此保持直到 5 月底。</p>
<p><img src="https://imageproxy.pbkrs.com/https://www.marketbeat.com/logos/articles/med_20260611133435_app2026-06-1111-57-19.PNG?x-oss-process=image/auto-orient,1/interlace,1/resize,w_1440,h_1440/quality,q_95/format,jpg" alt="" width="1200" height="683" original-src="https://imageproxy.pbkrs.com/https://www.marketbeat.com/logos/articles/med_20260611133435_app2026-06-1111-57-19.PNG"/></p>
<p>APP 股票在 5 月底试图突破，但卖家迅速将股价压回 200 日移动平均线以下，现在再次测试 50 日移动平均线。由于 RSI 也低于 50，APP 股票可以继续在您的观察名单上，直到它们在 50 日移动平均线以上做出重大突破。</p>

AMPX

APPX

<p>Fortinet、Amprius Technologies 和 AppLovin 尽管近期有所上涨，但仍显示出看跌的技术信号，如 MACD 反转和 RSI 弱势。Fortinet 面临内部人士抛售警告；Amprius 遇到做空者的担忧和亏损；AppLovin 显示出 “死亡交叉” 形态。这些指标暗示这些科技股的动能减弱，可能面临下行风险</p>

<p>Markets move faster than ever these days, and yesterday’s winners can quickly become today’s losers. When prices outpace fundamentals, traders often rely on technical indicators and signals to guide their decisions. Momentum indicators like the Relative Strength Index (RSI) don’t have prophetic powers, but they do give clues about where a stock might be headed and how much strength backs the move. Using a combination of indicators together can provide solid evidence that a downtrend is about to break. Or, in the case of these three stocks, that an uptrend is losing momentum.</p>

</div><p>The tech sector has been one of the most volatile parts of the market over the past few weeks, with the Nasdaq 100 fluctuating by more than 2% in a single day on multiple occasions. While volatile trading sessions make for fun times for day traders, it can be difficult to gauge the market when indices swing by 2% every day. That’s where technical analysis comes into play. Technical indicators utilize recent price data to generate actionable signals about shifts or continuations in momentum. By applying technical analysis, we can make educated predictions about a stock’s future path based on the intensity of buying or selling activity around it.</p>

</div><h2>Fortinet: Overbought Peak With Insider Selling Warning</h2>
<div class="lb-trans"><h2>Fortinet：超买峰值与内部人士卖出警告</h2>
</div><p>Fortinet Inc. NASDAQ: FTNT has been the face of the “software isn’t dead” narrative. The $106 billion cybersecurity firm has seen its stock accelerate more than 80% year-to-date (YTD), including more than 70% in the past three months alone.</p>
<div class="lb-trans"><p>Fortinet Inc. NASDAQ: FTNT 一直是 “软件并未死去” 叙述的代表。这家市值 1060 亿美元的网络安全公司，其股票年初至今（YTD）上涨超过 80%，其中过去三个月上涨超过 70%。</p>
</div><p>The software sector seemed to be in the crosshairs of agentic AI, and funds like the iShares Expanded Tech-Software Sector ETF BATS: IGV lost more than 35% of their value between September and April. However, strong earnings from companies like Fortinet showed that AI can complement software platforms rather than wipe them out. Fortinet smashed expectations in Q1 2026, beating both top and bottom line estimates and posting 20% year-over-year (YOY) revenue growth.</p>

</div><p>Management also raised full-year guidance and repurchased more than $800 million worth of stock. So why is this stock on a “time to sell” list? Because sometimes the most important technical signals aren’t shown on the charts. Insiders have been selling stock at a faster rate over the last two quarters, including a $23 million sale from CEO Ken Xie.</p>
<div class="lb-trans"><p>管理层还提高了全年指引，并回购了超过 8 亿美元的股票。那么，为什么这只股票会出现在 “卖出时机” 名单上呢？因为有时候，最重要的技术信号并不在图表上显示。内部人士在过去两个季度以更快的速度出售股票，包括首席执行官 Ken Xie 的 2300 万美元的出售。</p>

<p>There has been no significant insider buying in the past year, and insider selling at a technical top is often a warning sign. Widening Bollinger Bands indicate that volatile trading has become the norm for FTNT shares, and the Moving Average Convergence Divergence (MACD) indicator has turned bearish following the strong rally. The company’s long-term fundamentals still look promising, but it might be wise to take some short-term profits now.</p>

<p>AMPX might be heading for the dreaded double top pattern, and other signals suggest that the fun is over. Both the RSI and MACD have been trending down since the middle of March, and now the former has spent most of the last six weeks in bearish territory. AMPX isn’t profitable yet, and short sellers are openly questioning its revenue streams, so it would be wise to avoid this stock or take profits while you can.</p>
<div class="lb-trans"><p>AMPX 可能正朝着令人畏惧的双顶形态发展，其他信号表明乐趣已经结束。自三月中旬以来，RSI 和 MACD 均呈下行趋势，而前者在过去六周的大部分时间里处于看跌区域。AMPX 尚未盈利，空头卖家公开质疑其收入来源，因此明智的做法是避免这只股票或在可以时获利了结。</p>
</div><h2>AppLovin: Death Cross Overshadows Fundamental Strength</h2>
<div class="lb-trans"><h2>AppLovin：死亡交叉掩盖基本面强劲</h2>
</div><p>AppLovin Corp. NASDAQ: APP is already down more than 25% YTD, even though it grew revenue by more than 56% in Q1 2026, and remains well-regarded by analysts. But despite a strong fundamental picture, the stock is in the throes of a bear market that’s proving difficult to shake.</p>
