# Pre-market hot trades in US stocks: ASTS down 3% in pre-market trading: Launch setbacks lead to supply-demand imbalance, rating maintained at Hold

**Pre-market Hot Trades in US Stocks**

AST SpaceMobile is down 3.01% in pre-market trading. Based on recent news,

1.  On August 15, analysts maintained a hold rating on AST SpaceMobile, not including it in the recommended buy list. Analysts believe there are five other stocks with greater investment value, which may lead to a lack of investor confidence and a drop in stock price.

2.  On August 17, the company's management stated that as high-density orbital coverage is achieved, capital intensity will normalize. Nevertheless, the risk of rapid evolution in satellite hardware still exists, which may affect investors' expectations for the company's long-term development, leading to stock price volatility.

3.  On August 18, major launch alternatives faced setbacks, exacerbating the imbalance between supply and demand in the market. Launch issues from companies like Blue Origin, ULA, and Ariane 6 may impact AST SpaceMobile's satellite deployment plans, increasing market uncertainty and causing stock prices to drop. The satellite launch market faces an imbalance in supply and demand, increasing risks.
