Index Updates Skew Weekly ETF Flows

Index Updates Skew Weekly ETF Flows

Expect a lot of noise from ETF flows data this week and next.

On its face, the period between Dec. 10 and Dec. 16 was a bumper week for ETFs, with a net inflow of $78.2 billion despite significant volatility in the week from the Omicron COVID-19 variant and the Fed decision.

Indeed, the vast majority of the net flows came on Thursday, as $37.9 billion in flows were detected during a single trading session. But almost all of that amount is noise caused by the year-end rebalancing of the Nasdaq-100 and indexes from S&P Dow Jones Indices and CRSP.

Those three major index providers have been issuing pro-forma indexes through the first two weeks of December, with effective dates set either for next Monday or Tuesday. ETF managers following those indexes must realign the holdings and weights within their funds to align with the changes, requiring large sums of cash to do the job.

That’s why the SPDR S&P 500 ETF Trust (SPY) registered a whopping $6.34 billion in net inflows on Tuesday, despite the S&P 500 moving just 6 points that day, and added $9.13 billion in new assets despite a flat week for the major indicator.

Next week’s weekly flows data is also expected to be obscured by the rebalancing effect as institutional managers withdraw the excess liquidity needed to get their funds tracking their index properly.
