The Week

SPYM.US fell 0.22% this week to $90.60, from a prior close of $90.80 on Friday, 25 September 2026. The benchmark S&P 500 lost 0.27%, leaving SPYM.US about 0.05 percentage points ahead. The move was not one-way: after opening at $90.43 on Monday the ETF drifted lower, hitting a weekly low of $89.31 on Thursday, then bounced on Friday to close at $90.60. Weekly amplitude was 1.79%, so this was a mild pullback followed by a late-week recovery.

iShares Core S&P 500 This Week

The linked underlying, iShares Core S&P 500 (IVV), fell 0.22% to $773.10, from $774.83 previously. It opened Monday at $771.775, traded as high as $776.05 and as low as $762.11, with amplitude of 1.81%. Price action drifted lower through the first four sessions before Friday’s rebound, helped by a softer US jobs print and retreating Treasury yields, left the index near the higher end of its weekly range.

Leverage & Decay

SPYM.US aims to deliver 1x the daily move of iShares Core S&P 500, not 1x the cumulative weekly return. With the underlying down 0.22% this week, the theoretical 1x result is about -0.22%, and the actual move was also -0.22%, a gap of 0%. Daily rebalancing added almost no drag this week because the underlying path was fairly smooth. In choppier conditions, where the index alternates down and up days, rebalancing costs accumulate, and long-term returns can drift away from simple 1x cumulative performance.

iShares Core S&P 500 News

The week for the S&P 500, which IVV tracks, was shaped by Treasury yields and the jobs report. Early in the week oil and the 10-year yield climbed, pressuring the index. Then Thursday’s mild inflation data and Friday’s weaker-than-expected payrolls data cooled rate-hike concerns; the Nasdaq hit a record high and the S&P 500 recovered most of its losses. Against that backdrop, Nvidia announced a record $150 billion buyback, Tesla’s quarterly deliveries beat estimates, and Twilio and Vylor were added to the S&P 500. These company events were correlated with index moves, but the relationship is not a single causal chain.

The Week Ahead

The first macro batch lands on Monday, 5 October, with the S&P Global services PMI final reading and ISM non-manufacturing PMI; the question is whether services strength offsets growth worries after this week’s soft jobs data. Tuesday brings international trade and goods trade balance data, and Wednesday has EIA weekly crude inventories. For SPYM.US, the focus next week is whether the S&P 500 can extend Friday’s rebound and whether Treasury yields keep retreating.

In Short

This week leaves a single tension: SPYM.US fell only 0.22% and tracked the underlying and the S&P 500 closely, meaning index-level volatility was modest even as a stream of individual stock stories dominated headlines. The latest single-day capital snapshot shows large-lot buying well above mid- and small-lot flows, but that is one day and should be read only as a weak directional signal, not a weekly trend. The next test is whether the S&P 500 can hold its weekly high after the cooling in yields and jobs data, and whether services PMI data give the market a clearer macro anchor.
