Why Did NIO, RARE, MCD Stocks Fall To 52-Week Lows?

NIO stock fell to a 52-week low after Q2 earnings missed expectations and the company issued softer-than-expected Q3 guidance, accompanied by analyst downgrades. RARE plunged 44% after its Phase 3 ASPIRE Angelman study failed to meet both primary and secondary endpoints.

Why it matters: MCD declined as weaker second-quarter revenue and slower U.S. customer traffic pressured the stock.
