• NFLX had a weak price trend in the medium, short, and long terms, with a solid quality score as per Benzinga’s Edge Stock Rankings.

AST SpaceMobile

• ASTS was in the spotlight this week primarily due to financing news and timeline updates. On July 15, the company announced and priced a $1 billion private offering of convertible senior notes due 2034, sparking dilution concerns despite capped calls. It also updated that full commercial service is now targeted for early 2027, delayed from late 2026, due to launch provider uncertainties, while BlueBird 11 arrived at Cape Canaveral ahead of the planned August launch for satellites 11-13.

• Some retail investors were confident that the decline in ASTS stock was a buying opportunity.

SK Hynix

• SKHY dominated semiconductor headlines this week with its landmark Nasdaq ADR debut. The company raised approximately $26.5 billion in one of the largest U.S. listings by a foreign firm, with shares surging over 12-13% on debut, though they later pulled back amid broader chip sector volatility. Korean shares also plunged this week amid heavy profit-taking by institutions/foreigners. Meanwhile, Jim Cramer blamed SKHY for Taiwan Semiconductor Manufacturing Co. Ltd.‘s (NYSE:TSM) decline despite a strong earnings report.

• Retail investors were still confident of the AI’s memory bottleneck trade, with some thinking of buying the memory dips.

Its recent $250 billion U.S. investment expansion, announced on July 9, to boost AI memory production, remained a key positive theme, with analysts highlighting long-term supply opportunities and potential bottlenecks. The stock faced pressure on July 13 alongside peers, following SK Hynix’s post-listing moves, with active options trading and some profit-taking, though fundamentals stayed strong on high-bandwidth memory demand.
