Arista Networks Forecast: Bull Flag Puts $258 in Focus

Support Holds After Earnings-Fueled Rally

Arista Networks, Inc. (ANET) is in the computer-networking group and designs and sells high-performance networking products for data centers, cloud providers, and AI clusters. Its stock rallied to a new high of $214.89 in early-August, following the release of the company’s Q2 2026 earnings report, before pulling back. Since that high, ANET has pulled back to a low of $181.27 two weeks ago, providing a successful test of support near the prior high resistance zone of $179.80 and the 61.8% Fibonacci retracement of the prior advance at $179.02. That combination of support levels helped contain the pullback and now provides an important foundation for a potential renewed advance.

Multiple Support Tests Favor Buyers

In addition, the 50-day moving average was confirmed as dynamic trend support two weeks ago as well. That was its first test of that indicator as support since it was reclaimed during the sharp rally that followed the July low of $156.83. Notably, the success of that test was demonstrated by the sharp intraday advance with a strong close near the high of the range on that day.

The indicator was further strengthened as a support indicator on Monday, since Monday’s low of $186.11 was essentially at the 50-day moving average. It was followed by a bullish one-day reversal on Tuesday, which generated a higher daily low of $190.86 and a higher daily high of $194.69. The sequence of successful support tests followed by a bullish reversal adds to the evidence that buyers are defending the current retracement.

Bullish Flag Sets Up Breakout Potential

What is now of interest is the potential bullish flag continuation pattern that formed during the pullback and developed on key support at the 50-day moving average. A sharp approximately $58.00 (or 37%) advance preceded the flag consolidation pattern, providing a guide to assess a potential upside target if a successful upside breakout of the pattern follows soon. Assuming a $200.25 breakout level, that would generate an initial upside objective near $258.30 with a price-based flag target and $274.4 is the percentage-based alternative.

Other potential target levels from Fibonacci extensions into new highs on the weekly chart show additional potential upside targets. The initial $225.30 price zone stands out, as it is the only area marked by two levels, adding to its significance as a potential upside target if a bullish flag breakout triggers and is sustained. Therefore, a move above $200.25 would provide an important confirmation of the flag, with $225.30 emerging as an initial target before the larger measured objective near $258.30.
