NAS100 midweek: index holds 30300 after soft start, 2026-09-28
NAS100 sits at 30334.37 on Wednesday, down 234.70 points from Monday's open, with the week's range still set by Monday's 30617.83 high and 30079.80 low.
3 min readUSDMXN trades at 17.058 as of Wednesday's close, down from Monday's 17.1379 open. That is a slide of roughly 0.47 percent, or about 800 pips on this quote, across the first half of the week. The high so far is 17.1595, set Monday, and the low is 17.0467, printed Tuesday. Price has drifted along the lower edge of that range since.
The heavy move came Tuesday, when USDMXN dropped from a 17.1315 open to close at 17.0711. That leg ran ahead of the main US data of the week rather than in reaction to it, with the dollar leaking lower into the print. Wednesday's session has been thin and range-bound by comparison, volume well below the earlier bars, as the market waits.
US CPI is the pivot, due Wednesday at 12:30 GMT. Headline CPI y/y is forecast at 3.4 percent against 3.5 percent prior, with core CPI m/m seen at 0.2 percent after a flat 0.0 percent reading. If inflation runs hotter than forecast and the dollar bids, USDMXN can push back toward the Monday high near 17.16. A soft print keeps the peso on the front foot and the 17.05 area in focus. Thursday brings US PPI at 12:30 GMT, core PPI m/m forecast at 0.3 percent, which offers a second read on price pressure and a chance to confirm or fade the CPI move. Contrast this with a dollar-crosses backdrop where EUR/USD is reacting to the same US calendar from the other side.
As of Wednesday, LHFX sentiment shows 62 percent of open positions long USDMXN against 38 percent short. That skew leans toward more dollar upside from here, which sits against the week-to-date drop. When the crowd is long into a falling market, the CPI print becomes the moment that either validates the longs or forces them out.
The 17.0467 low from Tuesday is the line in the sand. Hold above it through the CPI reaction and the range stays intact, with 17.16 the upper marker. Break and close below 17.0467 and the round 17.00 handle becomes the next obvious reference. You can frame both paths off the same pivot rather than picking a single number, and you can watch how the spread behaves through the data if you open an LHFX account and track it live.
