Muddy Waters’ short report (Investopedia, March 27) alleging shady practices—down 20% then—pairs with today’s risk-off mood (S&P 5,700, Investopedia). X ties it to “tech selloff” (@algotradingdesk)—adtech’s volatile after a 700% 2024 run (Investopedia).

• Moderna (MRNA) – Down 5%: MRNA’s slipping 5% to ~$50 (projected from $53, Yahoo Finance base), per X (@JayGoonetilleke). A 7% drop last week (Investopedia) after trial setbacks (March 17, Investopedia) and tariff-driven cost fears (Reuters) weigh heavy—healthcare’s shaky (X @algotradingdesk). Investors shun biotechs—down 40% YTD (Investopedia).
• Novavax (NVAX) – Down 5%: NVAX’s down 5% to ~$12 (projected from $13, Yahoo Finance base), per X (@JayGoonetilleke). Vaccine makers falter post-PCE (2.8%, Yahoo Finance)—no COVID surge lifts demand (Forbes), and tariffs hit supply costs (Reuters).

• Taiwan Semiconductor (TSM) – Down 4%: TSM’s off 4% to ~$170 (projected from $177, Yahoo Finance base), per X (@JayGoonetilleke). China tensions and Trump’s tariffs (20% on China, Reuters) spark a semi selloff—Nasdaq’s tech rout (Investopedia) drags TSM down.

GLHR Takeaway

Today’s top 10 losers—PLTR (-8%) to AMD (-3%)—reflect a market reeling from Friday’s PCE inflation shock (2.8%) and Trump’s looming tariffs (April 2). Tech and crypto lead the plunge—$1 trillion in stock value (Forbes) and $100 billion in crypto cap (Mudrex) lost this week. Investors flee risk—X sentiment’s grim (@KobeissiLetter)—dip-buyers might wait for tariff clarity or a Fed pivot (June odds 58%, Cointelegraph).
