Astera Labs Inc ( ALAB ) shares are surging on Tuesday. Investors are piling into the semiconductor connectivity specialist ahead of its first quarter of 2026 earnings report.

The company will release these results after the market closes on Tuesday. The Nasdaq is up 1.28% while the S&P 500 has gained 0.74%, which could be adding to the stock’s gain.

Analyst Targets and Track Record

Wall Street analysts expect earnings per share of 49 cents, and revenue estimates sit at $292.36 million for the quarter.

Notably, Astera Labs ( ALAB ) has beaten EPS estimates in eight consecutive quarters. This consistent performance fuels high investor confidence.

Short Interest Pullback

Recent data shows a decline in bearish bets. Short interest fell from 15.50 million to 14.44 million shares during the last period. Currently, 11.11% of the company’s float remains sold short.

The current short interest would take 2.54 days to cover based on average daily volume.

Astera Labs Technical Levels To Watch

From a trend perspective, ALAB is stretched above its key moving averages, trading 23.8% above the 20-day SMA ($176.25) and 53.5% above the 50-day SMA ($142.15).

The moving-average structure is mixed: the 20-day SMA is above the 50-day SMA (bullish near-term), but the 50-day SMA remains below the 200-day SMA ($163.35) following the death cross in March—so longer-term trend followers often want to see that relationship repair over time.
