In the last trading session, Wall Street rallied on softer-than-expected inflation data that has lowered bets on the Fed’s aggressive rate hikes. Among the top ETFs, (SPY Quick QuoteSPY - Free Report) gained 2.1% and (DIA Quick QuoteDIA - Free Report) added 1.6%, while (QQQ Quick QuoteQQQ - Free Report) moved 2.8% higher on the day.

Two more specialized ETFs are worth noting as both saw trading volume that was far outside of normal.
