2026.4.15 US Stock Daily | S&P and Nasdaq Both Hit All-Time Highs as Market Completely Shrugs Off War

The S&P closed at 7022.95 (+0.80%), the Nasdaq at 24016.02 (+1.59%), both setting new all-time closing records. The S&P surpassed its January 27 previous high, and the Nasdaq broke through its October 29 previous high. The Dow finished at 48463.72, down a marginal 0.15%, failing to keep up.

The divergence is telling. Tech XLK gained 1.60%, Consumer Discretionary XLY rose 1.49%, while Industrials XLI fell 1.25% and Materials XLB dropped 1.21%. Money is chasing growth, not cyclicals. VIX at 18.17, already back to pre-conflict levels.

The standout individual stock was Tesla, surging 7.62% to close at 391.95 on volume of 113 million shares. Microsoft rose 4.61% to 411.22, Apple gained 2.94%. These three alone dragged the Nasdaq to its new high. Nvidia was up 1.20% but slipped 0.43% after hours — worth noting.

Why is the market this aggressive? Polymarket gave the bluntest answer: the probability of US-Iran military action ending before April 17 is now priced at 100%. One hundred. Not ninety, not ninety-five. Pakistan disclosed that US-Iran talks are expected to resume in Islamabad next week, and Trump spoke with Qatar’s Emir about regional developments. The Senate voted 52-47 to reject a resolution limiting presidential war powers against Iran — superficially hawkish, but in practice it handed Trump more negotiating leverage. Whether to strike is his call, and that paradoxically accelerated negotiations.

But the Middle East is far from settled. Israel warned the same day it might restart conflict with Iran and continue strikes against Hezbollah. On Polymarket, the probability of an Israel-Hezbollah ceasefire by April 15 sits at just 20%. Lebanon’s Hezbollah said it agrees to a ceasefire but Israel must comply first. On one track, the US and Iran are talking; on the other, Israel is fighting. The two timelines are not in sync.

One story deserves separate attention. Bloomberg reported the US is investigating a batch of suspicious oil trades that occurred just before Trump’s policy reversal. The timing is surgically precise. If confirmed, this would be a political bomb bigger than the war itself.

On the capital flows front, there’s a data point being overlooked: US international capital net inflows hit $184.5 billion in February, versus negative $25 billion in the prior reading. A single-month swing from net outflows to nearly $200 billion in net inflows. Long-term capital net inflows were $58.6 billion, up from $15.5 billion prior. Foreign capital was flooding back into dollar assets as early as February, well before market sentiment recovered. Smart money was buying at peak panic.

The 10-year Treasury yield closed at 4.28%, rising over 3 basis points into the close. The window where stocks and bonds rallied together has shut — bonds are now trading “risk receding means no rate cuts needed.” On Polymarket, the probability of the Fed holding rates steady at the April meeting is 99%, with both 25bp and 50bp cuts at 0%. The dollar index at 98.08 barely moved, oil at 91.21 was essentially flat. Commodities and FX are quiet — all the action is concentrated in equities.

The Dow lagged because of its composition. Industrials and healthcare dragged it down, with XLI falling 1.25% and XLV dropping 0.71%. The Dow has only just clawed back to its year-start level after a roughly 10% decline from its highs, while the Nasdaq is already printing new records. This is not a healthy broad rally — it’s large-cap tech putting on a solo performance.

The current state: the market has fully priced in Middle East peace. If US-Iran talks hit any unexpected breakdown next week, an oil rebound combined with a risk appetite reversal would produce a swift pullback. The S&P just cleared the round 7000 level — there’s no technical resistance above, but no historical anchors either. This one-directional surge is fueled by short capitulation, not new positioning. Just look at Nvidia and Amazon both dropping after hours. How long the momentum lasts depends entirely on progress at the negotiating table. A single push notification reading “Israel launches new round of strikes on Iran” would be enough to send the VIX jumping back above 25.
