U.S. CPI growth in September exceeded expectations, pushing market bets on a Federal Reserve rate hike in October to 50%. Impacted by this, the Russell 2000 index fell 1.9% on Wednesday, with approximately four-fifths of its constituent stocks recording declines. It has now cumulatively fallen 11% from its August high, officially entering a technical correction for the first time since March this year. Analysts point out that small-cap stocks are highly sensitive to interest rates, and inflation data increases the risk of policy rate hikes, posing a continuous and long-term headwind for them.
