Investment Bankers/Brokers/Service

BlackRock Inc. vs The Goldman Sachs Group Inc.

WatchlistBLK / GSPrices through Oct 22, 2026

Why these are rivals: #2 and #3 by market value ($255B vs $174B) in Nasdaq's "Investment Bankers/Brokers/Service" industry; SEC SIC 6211 / 6211 (same major group); #2 and #3 by market value ($255B vs $174B) with SEC SIC 6211 (Security Brokers, Dealers & Flotation Companies).

Rivals, but right now the price gap does not have a measured habit of closing, so there is no paper idea, whatever the gap.

  • Mean reversion: ADF t-statistic of the spread: -2.71 (needs <= -2.873 (5% critical value))
