Recently Quest Diagnostics Incorporated has paid out, on average, around 18.41% of net profits as dividends. That has enabled analysts to estimate a "forward annual dividend yield" of 1.88% of the current stock value.

However, indirectly, the new 50% lower share price could have impacted the market appetite for Quest Diagnostics Incorporated shares which in turn could have impacted Quest Diagnostics Incorporated's share price.
