S&P 500 Ends Week With Longest Losing Streak Since August

The S&P 500 declined each trading day this week, marking its longest consecutive losing streak since August. The index finished the week down 2.0%, leaving it 3.4% below the June 2 record close and 7.4% higher year-to-date.

The index has traded below its 50-day moving average since June 26, 2026, while remaining above its 200-day moving average since April 8, 2026. The 50-day average has been above the 200-day average since July 1, 2025, a configuration often referenced by market participants when assessing medium-term trends.

Intraday volatility has been notable but subdued relative to past spikes. Over the past 20 trading days, the average intraday range from low to high was 1.30%. The largest recent intraday swing occurred on April 9, 2025, when the S&P moved 10.77% in a single session; the most extreme one-day range on record in recent years was 19.10% on December 24, 2018.

Performance differs by weighting method. The standard S&P 500 is market-capitalization weighted, giving larger companies greater influence on index returns. The S&P 500 Equal Weight Index assigns the same fixed weight to each constituent. Year to date, the cap-weighted S&P 500 is up 7.4%, while the equal-weighted version is up 11.0%. Common ETFs tied to the cap-weighted index include IVV, SPY and VOO; RSP tracks the equal-weighted index.

Historical drawdowns provide context for the scale of past selloffs. After a then all-time high on October 9, 2007 at 1,565.15, the index fell about 57% to close at 676.53 on March 9, 2009 during the Global Financial Crisis. The S&P did not surpass that 2007 high again until March 28, 2013, when it closed at 1,569.19.

The S&P remains in positive territory for the year and continues to trade above its 200-day moving average. The recent daily declines increased the distance from the June peak but left the index with a year-to-date gain of 7.4%.
