Technical outlook: Aster slides as overhead pressure swells:

$ASTER is edging lower below the 50 Exponential Moving Average (EMA) at $1.06, the 100 EMA at $1.09 and the 200 EMA at $1.14 on the 4-hour chart. The Relative Strength Index (RSI) sits at 50 (neutral), which may close the day in the bearish region. A declining RSI toward oversold territory indicates increasing bearish momentum.

Although the Moving Average Convergence Divergence (MACD) indicator on the same chart remains above its mean line, it shows weakness and is likely to confirm a sell signal in upcoming sessions if bulls fail to repair the uptrend.

Traders will look for the blue MACD line crossing below the red signal line to validate the bearish thesis. An extended decline below the pivotal $1.00 level could push Aster toward Monday's low of $0.88.

A break above the 50 EMA at $1.06 will maintain the bullish narrative. Other key areas of interest for traders are the 100 EMA at $1.09 and the 200 EMA at $1.14, which could cap rebounds.
