GOLDMAN SACHS TRADING DESK VIEWS

Market Summary  

▪ Overall market activity decreased by 7% week-over-week to 15.7 billion shares from 16.9 billion shares.  

▪ The off-exchange market share for the week rose to 51%, an 8% increase compared to the 2024 average of 47%.  

▪ E-mini S&P 500 top-of-book liquidity fell by 12% relative to the 10-day average.  

▪ S&P 500 spreads decreased by 5% compared to the 10-day average but increased by 8% compared to the 2024 average.  

▪ Russell 2000 spreads were down by 1% compared to the 10-day average but up by 10% against the 2024 average.  

▪ The proportion of ETFs by notional as a percentage of the tape increased by 10% relative to the 10-day average, comprising 22% of the share volume.  

▪ Last week, retail flows showed a net buy imbalance of $10 billion.

Throughout the continuous trading session (excluding auctions and pre/post-market), a greater number of shares are traded off exchange as spreads increase; conversely, this trend reverses on a notional basis.

In 2025, up to July, shares with spreads greater than 25 bps tend to be traded more off-exchange, likely influenced by retail trading in lower-priced stocks (this specific share category has the lowest average price of the four categories).

In terms of shares, the trading volumes are fairly distributed among the four spread categories, with the 10-25 bps category accounting for 31% of trades.

On a notional basis, the majority of trading occurs in the <5 bps category; when this category is combined with the 5-10 bps category, together they represent 64% of notional trading activity.

The narrower spreads seen in higher notional stocks may be partly due to the Mag 7 symbols, which, being more popular, have higher share prices and benefit from tighter spreads
