Bad S&P 500 Earnings Are Playing Right Into the Fed’s Hands

Was it good or bad this week when Alphabet Inc. told investors that advertising demand that helped swell its top line 50% in two years is starting to soften? Depends on what you mean by bad, and rarely has an argument over definitions meant more for markets and the economy.

Obviously it was bad for the Google parent’s shareholders, who saw $70 billion erased in a stroke. Tech bulls at large took a bath, with the Nasdaq 100 slumping 2.3% Wednesday. And the news didn’t help anyone hoping the economy will avoid a recession, given the famously forward-looking aspect of the ad market.

But those audiences aren’t everyone. Another is people worried that inflation remains beyond any means of subduing it. They include Jerome Powell, whose Federal Reserve is doing everything it can to put a brake on spiraling prices.

For them, a case can be made that bad corporate news has started to become good -- or at least a necessary evil -- when taken as a signal of cooling demand, something that’s ultimately a positive for economic stability and, one day, markets themselves. It’s a role long played by macro data points -- a weak GDP print, for instance, can sometimes spark a market rally -- but rarely by micro ones.
