Insmed's Quarterly Results Fail to Allay Investor Doubts

Insmed (NASDAQ:INSM) stock performance was dampened by cautious investor sentiment despite stronger‑than‑expected quarterly results.

Alger Mid Cap Focus Fund Portfolio Impact

■The fund outperformed the Russell Midcap Growth Index, driven by strength in Information Technology and Health Care

■Communication Services and Consumer Discretionary detracted from overall performance
