SPY (SPY) Up or Down on July 13?

Platform comparison

Market context

SPY closed at $754.94 on Friday, 10 July, setting the baseline for Monday’s binary outcome, while intraday trading has already tested support near $748 and resistance at $755.42[1][2]. The crowd-implied 24% probability for an “Up” close reflects a market leaning heavily toward a pullback, a stance that aligns with recent July behaviour where mid-month sessions often see profit-taking after early-quarter rallies[4]. Historically, July 13 falls in a window where the S&P 500 has resolved down in roughly 60% of cases over the past decade when the prior week ended near all-time highs, mirroring today’s position just 3.7% below SPY’s 52-week peak of $760.40[4].

Traders should monitor the pre-market futures signal and any overnight moves in Treasury yields, as a spike in the 10-year rate above 4.5% could trigger a risk-off reaction in equities before the open[2]. The key catalyst is the release of the June retail sales data, scheduled for 08:30 EDT, which the market will interpret as a proxy for consumer resilience amid persistent inflation concerns[3]. Additionally, watch for any commentary from Federal Reserve officials on the inflation outlook, as recent remarks have heightened sensitivity to forward guidance; a hawkish tone could amplify downside pressure on SPY before the close[1].
