In this episode of ETF Spotlight, I speak with Brad Loncar, CEO of Loncar Investments. Brad is in Chicago to attend the annual meeting of ASCO (American Society of Clinical Oncology). It is the world’s largest and most prestigious cancer conference where participants learn about the latest developments in treating the disease.Brad explains why ASCO is so important and how he uses it as an investor.The global market for cancer drugs is estimated to be about $123 billion and big players are investing heavily to gain an edge in this increasingly competitive market. Pharmaceutical giant Bristol-Myers BMY, a pioneer in immunotherapy, is acquiring rival Celgene CELG for $74 billion.Merck MRK is acquiring cancer drug developer Peloton Therapeutics for $1.05 billion. The announcement came as Peloton was preparing for its IPO.
