Nasdaq 100 Stocks SEC Filings — May 18, 2026
The 18 filings reveal a bifurcated landscape: while Genco Shipping & Trading and CoStar Group show strong operational turnarounds and proactive capital allocation, several biotech and cash-burning companies (Estrella Immunopharma, Madison Technologies) face liquidity pressures. Period-over-period comparisons highlight Genco's net income swing of +$21.2M YoY and CoStar's $1.5B buyback authorization, contrasting with Estrella's 28.5% G&A surge and Madison's zero revenue. Insider activity is limited but notable: Genco's CEO actively defends against a tender offer, while Acadia Healthcare faces a $105M adverse verdict. Forward-looking catalysts include MetaVia's ADA abstracts and ImmunityBio's BCG approval path. Sector themes center on capital discipline (shipping, real estate) versus speculative biotech spending, with a cautious tech hedge evidenced by Arkadios Wealth Advisors' large QQQ put positions.
