The month of June started with a bang, extending the bull rally. The optimism over accelerating economic activities as many states reopened, a booming technology sector, an unprecedented stimulus from the central bank and the government, and hopes of a potential coronavirus vaccine were the biggest catalysts in driving the stocks higher.

Additionally, the Fed’s move to provide liquidity in the markets and the Trump administration’s $1 trillion infrastructure proposal added to the strength. The central bank announced that it would begin purchasing individual corporate bonds as part of its emergency lending program to inject liquidity into the virus-stricken economy.

However, renewed concerns over a second wave of coronavirus infections and Federal Reserve’s dim outlook made investors’ jittery last week. Most notably, Texas reported 2,504 new coronavirus cases, the highest one-day total since the pandemic emerged. A month into its reopening, Florida reported 8,553 new cases — the maximum in any seven-day period — and California reported the highest number of hospitalizations since May 13 that have risen in nine of the past 10 day.
