Astera Labs (ALAB) builds a tactical base

We got a question on the chart for Astera Labs (ALAB).

ALAB is building a November 2025 into January 2026 ascending triangle bottoming pattern within the stock's longer-term uptrend as defined by its rising 200-day moving day moving average at 138.54.

Defending the zone of rising 13-, 26-, and 40-day moving averages from 168.66 down to 158.91 would keep the immediate pattern constructive within this developing bullish triangle with the potential for a breakout above the pattern neckline at 182.53-184.98. This breakout would confirm the triangle with upside potential beyond the late October peak at 201.86 toward the early October highs at 229.95-232.00 and the triangle pattern count at 240. In addition, a retest of the 2025 peak at 262.90 is not ruled out under this scenario.

The last two higher lows within the developing ascending triangle at 151.10 and 140.24 offer additional support if ALAB struggles to hold the daily moving averages highlighted above.

Volume indicators show bottoming signs from mid October into January in support of the developing triangle pattern for ALAB's stock price.
