S&P 500: Is the Top Finally In? Thinning Liquidity, Hot CPI Cloud Market Outlook

 | Apr 11, 2024 16:43

Stocks finished the day lower following the hotter CPI report. The S&P 500 was all over the place, though, trading with big swings. These swings seem to be a sign to me of a market that is becoming less liquid. We saw this a lot in 2022, especially as reserve balances held at the Fed fell.

Over the past few trading sessions, we have seen the size of the top of the book on the S&P 500 futures start to thin out. While it is not as thin as we saw in 2022, it caught my attention enough that I thought I should point it out now, especially since we know that the Bank Term Fund Program is now unwinding, and reserve balances are likely to head lower from their current levels.

The top of the book tells us how big the size of the bid or offer is, and when the size of that bid and offer diminishes, it can make the market move more than when the bid and offer have a large amount of size.

The red and green bars represent the depth of the book, the wider periods represent more depth, and the smaller values show less depth. The light blue line is the S&P 500. The chart clearly shows how the depth of the book gets wider when the index rises and thinner when the index falls.
