Signs keep popping up that we're at the end of this long bull run. Here's another warning shot: Analysts at the Wall Street behemoths HSBC, Citigroup and Morgan Stanley "see mounting evidence that global markets are in the last stage of their rallies before a downturn in the business cycle," per Bloomberg.

  • "[T]he breakdown of long-standing relationships between stocks, bonds and commodities, as well as investors ignoring valuation fundamentals and data, [mean] stock and credit markets are at risk of a painful drop."
  • "[L]ike they did in the run-up to the 2007 crisis, investors are pricing assets based on the risks specific to an individual security and industry, and shrugging off broader drivers, such as the latest release of manufacturing data."
  • Why it matters 1: "As traders look for excuses to stay bullish, traditional relationships within and between asset classes tend to break down."
  • Why it matters 2: "[A] classic late-cycle expansion -- an economy with full employment and slowing momentum -- tends to see a decline in corporate profit margins. The U.S. is in the mature stage of the cycle -- 80 percent of completion since the last trough -- based on margin patterns going back to the 1950s."

Be smart: A Bloomberg video points out that investors are looking for the "next piece of sugar," which could include progress on tax cuts.

Boeing and researchers at the University of Arizona say their experiment with a live virus on an unoccupied airplane proves that the cleaning methods currently used by airlines are effective in destroying the virus that causes COVID-19.

Why it matters: Deep cleaning aircraft between flights is one of many tactics the airline industry is using to try to restore public confidence in flying during the pandemic. The researchers say their study proves there is virtually no risk of transmission from touching objects including armrests, tray tables, overhead bins or lavatory handles on a plane.

Senate Democrats block vote on McConnell's targeted COVID relief bill

Senate Democrats on Wednesday blocked a vote on Republicans' $500 billion targeted COVID-19 relief bill, a far less comprehensive package than the $1.8 trillion+ deal currently being negotiated between the Trump administration and House Democrats.

Why it matters: There's little appetite in the Senate for a stimulus bill with a price tag as large as what President Trump and House Speaker Nancy Pelosi have been calling for. Senate Majority Leader Mitch McConnell's (R-Ky.) "skinny" proposal was mostly seen as a political maneuver, as it had little chance of making it out of the Senate.
