“This was certainly robust. Investors are optimistic that we will get continued strong and even stronger numbers,” said Julian Brigden, co-founder and president of MI2 Partners.

“This does raise questions about how long the Fed can hold the line,” he said, adding that there is a real risk that the central bank may suddenly become more concerned about inflation. “The market may have to factor in more rate hikes.”

But another market expert argued that investors shouldn’t worry about the Fed raising rates too quickly. For one, the Fed still has to finish cutting back on, or tapering, bond purchases. That process has only just begun.

Fed chair Jerome Powell was adamant during a press conference Thursday that he and other Fed members are fully aware that the job market is still not at full employment levels just yet.

“Powell did a masterful job of relieving investor worries that the Fed would act too aggressively following the taper. The market is still feeding off that,” said Mark Luschini, chief investment strategist at Janney.
