When it comes to question of "who is right" in the market, the debate usually ends with credit (investment grade) or equity (and its high beta equivalents in the fixed income arena: high yield bonds). And since the question is rhetorical we will kill the suspense and cut straight to the answer: always, and without fail, credit. The chart below shows that once the manipulated ramp up in high beta risk equivalents such as the ES and HY is over (especially since IG is now losing its artificial JPM-induced bid, or technically offer, which is unwinding positions across all vintages and buying protection to close short positions), the way down to a credit-implied fair value of 1335 on the S&P will be fast and furious.
