VIAV: Ascending Triangle detected on 19 Mar 2026

VIAV is forming an ascending triangle as it approaches key resistance at $34.05, just shy of the stock's $35.61 52-week high from March 5, 2026. At $32.44, the stock is trading 300% above its 52-week low, having gained 81.43% over three months. The pattern structure scores 15.0/15 (perfect), with volume ratio of 1.28x average and breakout strength of 13.0/13. RSI at 62.39 shows controlled momentum (not overbought), while the pattern sits 76% up the Bollinger Bands, indicating room to run. MACD histogram is negative at -0.17, a minor caution, but overall the 83.2 overall score reflects a high-quality continuation setup.

VIAV's Q2 fiscal 2026 earnings came in at the high end of guidance, driven by strength across most end markets, with management expecting strong momentum in data center ecosystem and aerospace & defense to continue through the calendar year. The catalyst-rich environment includes a March 12, 2026 launch of the TestCenter D2 1.6T Appliance for 1.6T Ethernet networks aimed at cloud providers and hyperscalers, and shares jumped 7.6% after the company launched a new network security product (Observer Threat Forensics) and received a significant price target increase from an analyst on March 18. VIAVI earned its tenth consecutive Lightwave Innovation Award, with six solutions recognized including the TestCenter 1.6T Platform. The AI/1.6T Ethernet narrative directly addresses hyperscale data center buildout, explaining the 23.35% monthly gain.

A successful breakout above $34.05 resistance would target $34.44 (conservative measure move), with potential extension toward the $35.61 52-week high if volume maintains the current 1.28x ratio. Win probability is 63.02%, above the 50% baseline threshold. The invalidation level sits at $30.14 support; a close below that level would signal pattern failure and suggest profit-taking has overwhelmed buyers. Volume confirmation is critical—sustained daily volume above 6.0M shares supports upside conviction. The ascending triangle structure suggests a directional resolution soon; historical data shows these patterns resolve 60-70% upside when formed in established uptrends.

VIAV's price-to-sales ratio has exceeded six, a multi-year high, suggesting the stock is expensive and potentially at risk of profit-taking. CMO Paul McNab sold 3,551 shares on March 2, 2026 while stock was surging to 52-week highs, though he retained over 18,000 shares, suggesting measured positioning rather than alarm. Recent AI and optical test announcements have produced mixed to negative moves, with a -6.53% reaction on March 3 and a -2.41% move on March 17, indicating that not all product news translates to sustained price gains. Q3 fiscal 2026 guidance (ending March 28, 2026) projects revenue of $386-$400M and EPS of $0.22-$0.24—these results report on April 25 or May 2, near-term earnings risk. Beta of 0.82 and volatility at 9.63% are relatively moderate, but the stock's 81% three-month surge suggests potential for reversion if momentum stalls. No major downgrades noted, but valuation and mixed catalyst follow-through warrant caution.
