Volatile markets can make it difficult for investors to decide on a course of action, especially when 2% daily moves are the norm.
When markets become volatile, technical analysis becomes more crucial for identifying trends and momentum shifts.
Fortinet, Amprius Technologies, and AppLovin are three stocks showing bearish technical signals despite gaining 20% or more over the past 12 months, indicating it might be time to hit the cash register.
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.
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.
Each of the following three stocks fits a specific set of criteria. All three have gained 20% or more over the last 12 months, driven by various fundamental and macro factors. However, these stocks are currently showing technical warning signs that investors should carefully examine.
Fortinet: Overbought Peak With Insider Selling Warning
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.
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.
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.
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.
Amprius Technologies Inc. (NYSE: AMPX) lacks the strong fundamental foundation that Fortinet has, which means its downturn could be much sharper.
The lithium-ion battery producer is beating revenue estimates, and its stock is still up more than 100% YTD, but the rally is faltering amid concerns about the quality of its revenue. A recent report by a short-seller claims that the company inflates its orders and engages in undisclosed transactions with a related party affiliated with Amprius’s CEO.
The company also reported a larger-than-expected loss in its Q1 2026 earnings report on May 6, and insiders have sold $83 million worth of shares over the last three quarters, without a single buy.
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.
AppLovin: Death Cross Overshadows Fundamental Strength
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.
It may seem counterintuitive, but APP shares probably won’t reflect the company’s strength until the technical setup improves.
An early-March Death Cross indicated the stock has a long way to go before regaining buying momentum.
The Death Cross sent the stock plunging under the 50-day and 200-day moving averages, where it stayed until late May.
APP shares tried to break out at the end of May, but sellers quickly pushed the share price back below the 200-day moving average, and now it's once again testing the 50-day moving average. With the RSI also below 50, APP shares can remain on your watchlist until they make a significant move above the 50-day moving average.
Four leading AI models discuss this article
"Technical indicators like the Death Cross are frequently lagging indicators that punish reactive investors while ignoring the fundamental re-acceleration potential of high-growth software firms."
The article conflates disparate risk profiles. Fortinet (FTNT) is a high-quality compounder where insider selling is often programmatic, not necessarily a signal of fundamental decay; selling into strength here risks missing a secular cybersecurity tailwind. Conversely, Amprius (AMPX) is a speculative micro-cap where technicals are secondary to the existential threat of the short-seller allegations. AppLovin (APP) is the most interesting; the 'Death Cross' is a lagging indicator that often traps retail investors into selling at the exact moment institutional accumulation begins. The article ignores that technicals are reflexive—they work because people believe they work, not because they predict the future.
If these technical signals are widely observed by institutional algorithms, they can trigger automated sell-stops that create a self-fulfilling prophecy, regardless of the underlying fundamental strength.
"AMPX warrants caution on revenue authenticity grounds (material risk), but FTNT and APP's technical weakness is likely noise masking solid fundamentals—conflating chart patterns with sell signals is dangerous when earnings are accelerating."
This article conflates two distinct failure modes: technical deterioration and fundamental weakness. FTNT's 80% YTD rally with 20% YoY revenue growth and raised guidance doesn't justify a sell on MACD crossovers alone—insider selling at peaks is noise without context (tax planning, diversification). AMPX is the real concern: short-seller allegations about related-party transactions and revenue quality are material, not technical. APP's 56% revenue growth contradicts the bearish technical setup; a Death Cross after a 25% YTD decline is capitulation, not warning. The article treats momentum indicators as predictive when they're often lagging. Missing: earnings revisions, analyst downgrades, and whether these technicals preceded or followed fundamental deterioration.
Technical signals do precede fundamental misses—insider selling often signals management's private doubts, and AMPX's short-seller report may prove prescient if revenue quality genuinely deteriorates. Momentum reversals can be self-fulfilling in thin-float names.
"Fortinet’s fundamental momentum and capital return program outweigh the technical warning signs the article highlights."
The article flags technical breakdowns in FTNT, AMPX, and APP after strong runs, but glosses over how Fortinet’s Q1 2026 beat, raised guidance, and $800M buyback dwarf the $23M CEO sale. Widening Bollinger Bands and a bearish MACD often precede continuation in high-growth software names rather than reversal. AMPX carries real short-seller and profitability risks, yet FTNT’s 20% YOY revenue growth and sector tailwinds from AI-complemented cybersecurity remain intact. Investors risk exiting too early if they treat RSI/MACD crossovers as primary signals instead of lagging confirmation. Context missing: forward P/E compression already prices in some slowdown.
MACD turning negative after an 80% YTD run has historically preceded 15-25% drawdowns in FTNT even when fundamentals stayed solid, and insider sales at peaks have coincided with multi-quarter consolidation.
"Technical momentum signals alone are insufficient to time exits; fundamentals and catalysts could sustain or re-rate these names despite near-term chart warnings."
The article leans on lagging technicals to justify a broad sell stance, but that ignores ongoing fundamentals and catalysts. Fortinet’s Q1 beat, 20%+ YoY revenue growth, and sizable buybacks offset insider selling as a near-term risk; Amprius’ revenue concerns and losses are valid, yet the battery space remains volatile with potential catalysts; AppLovin’s Death Cross and RSI readings may just reflect a broader software/ads cycle rather than a lasting top. In volatile markets, technicals can whipsaw, and durable trends often hinge on earnings quality and sector tailwinds (cybersecurity, AI-driven ad tech, energy storage) rather than chart patterns alone.
Insider selling at FTNT, a confirmed Death Cross at APP, and a deteriorating RSI at AMPX are not just noise—they signal real momentum deterioration that could precede meaningful downside, especially if fundamentals fail to keep up with the hype.
"Technical signals act as reflexive catalysts for institutional de-risking, regardless of the underlying fundamental health."
Grok, your focus on FTNT's historical 15-25% drawdowns following MACD crossovers is the only quantitative anchor here. While others dismiss technicals as 'lagging,' they ignore the reflexive nature of institutional risk management. If these signals trigger systematic de-risking, the 'why' behind the sell-off becomes irrelevant. We are ignoring the liquidity risk: in a market addicted to momentum, technical breakdowns often act as the catalyst that forces fundamental reassessment, not just a reaction to it.
"Technical cascades amplify existing weakness; they don't create it from thin air."
Gemini's reflexivity argument is seductive but inverts causality. Institutional risk management doesn't *create* fundamental deterioration—it *accelerates* existing weakness. FTNT's $800M buyback and raised guidance are real; a MACD crossover triggering forced selling doesn't invalidate that. The liquidity risk is real only if fundamentals crack. We're conflating 'technicals matter' with 'technicals matter more than earnings.' They don't. If FTNT misses Q2, the Death Cross becomes prophecy. If it beats, it's noise.
"Technical triggers can override buyback support in high-ownership names like FTNT, risking spillover to APP and AMPX."
Claude overlooks that FTNT's institutional ownership amplifies technical triggers into rapid de-risking before buybacks can stabilize. This reflexivity links directly to AMPX's short-seller pressure, where thin liquidity turns allegations into price action faster than any fundamental rebuttal. The missing piece is how sector rotation in software could cascade across all three names regardless of individual guidance.
"Sector rotation can drive cross-name downside even when fundamentals look solid; cross-asset correlation matters more than reflexive signals."
Grok, your reflexivity angle is interesting, but it treats sector rotation as a trigger rather than a force. The real risk is cross-name correlation during a growth-to-value shift: if software buyers reprioritize budgets away from AI-heavy security (FTNT) toward steadier cash-flow names, all three can slip even if individual results look solid. A cross-asset co-movement lens would help separate idiosyncratic risk from macro rotation, beyond MACD or RSI signals.
The panelists agreed that relying solely on technical indicators like MACD crossovers and RSI readings can be misleading and may not accurately predict future performance. They emphasized the importance of considering ongoing fundamentals, earnings quality, and sector tailwinds when making investment decisions.
Fortinet's (FTNT) strong fundamentals, including 20%+ YoY revenue growth and a sizable buyback, offset insider selling as a near-term risk.
