According to Eric Balchunas, the Vanguard S&P 500 ETF (VOO) is close to surpassing the SPDR S&P 500 ETF Trust (SPY) in asset value, being only $5 billion behind. Traders should monitor this development as it signals potential shifts in trading volumes and market dynamics. Balchunas suggests this transition may occur imminently, highlighting a possible new era in ETF market leadership.

According to Eric Balchunas, $SPY is up 50 basis points in pre-market trading. However, traders should remain cautious due to a historical pattern of selloffs following Philadelphia sports championships, as seen after the 2018 Super Bowl, which coincided with the 'Volmageddon' market event.

According to Eric Balchunas, the asset gap between VOO and SPY is $5 billion. SPY is experiencing mild inflows, attributed to the rise in stock prices over recent days, indicating resilience despite expectations of a quicker resolution to the asset gap battle.

According to Eric Balchunas, the gap between VOO and SPY has widened to $6 billion. This development follows a significant trading day where traders took advantage of a dip in SPY, buying on the basis of a discrepancy between dramatic media headlines and market reality. This arbitrage strategy, previously effective during Trump’s first term, was employed to capitalize on market movements. The persistence of this gap is noteworthy for traders monitoring ETF flows.
