Unless the administration continues to pump out good news & bullish sentiment
Since the US-Iran-Israel conflict, there has been a growing structural divergence between how retail traders navigate the market. Pure discretionary traders (ones that purely draw lines on charts, follow bollinger bands, ICT, etc) and quants – the latter typically don’t interpret market movements through current events.
What quants typically do is run systematic pre-defined strategies that are historically indifferent to daily news flow. Discretionary traders are blaming recent losses on market volatility, and even quants are noticing a significant irregularity between fundamentals & price.
For the first time in years, breaking news is consistently playing a bigger role in the market. Announcements continue to cause sudden surges and dips, irrespective of underlying market conditions. The market is essentially contingent on marketing.
The Problem
A tweet, a ceasefire rumor, a supply chain headline, a geopolitical update, triggers an algorithmic reaction within milliseconds.
Billions move before any human has assessed the information. The original post gets walked back or proves irrelevant, but the price has already shifted, and the next wave of participants is now reacting to that price movement rather than the underlying information. This loop runs dozens of times per session.
“Current prices aren’t a consensus view of fair value. They’re a running average of thousands of incomplete, often false, real-time information shocks.” – Carson Hein, quantitative trader
The consequence is that price discovery, a markets’ core function, is increasingly unreliable. The capital flows to the wrong places & according to quant traders, the market is overpriced. Legitimate value gets systematically ignored.
Trading strategies including quant will still work regardless of valuation. However, on the assumption that prices eventually reflect fundamentals, this is a regime-level problem that needs correction.
The Data
Every major institutional valuation metric is simultaneously at extremes historically associated with severe corrections.

The S&P 500‘s forward P/E currently exceeds 28. For context, it’s roughly 65% above its 100-year average. The counterargument is straightforward: the market is at all-time highs. Bears who have cited these same metrics since 2020 have been wrong, and wrong at cost.
“Quantitatively, price is where it belongs. Fundamentally, it has no business being here. That gap doesn’t stay open forever.” — Carson Hein, co-founder of QuantMap
The Problem:
A market running on sentiment rather than fundamentals can keep climbing, but only as long as the news keeps delivering. This recent China trade deal is a real catalyst, and if that momentum continues with further de-escalation, tariff rollbacks, or fresh macro tailwinds, the gap between current prices and underlying value can legitimately narrow.
The bull case isn’t completely irrational… It just depends on the headlines staying cooperative and Trump continuing to pump the market.
The problem is the asymmetry. On the way up, positive surprises get priced in gradually and enthusiastically. On the way down, the absence of good news, let alone bad news, could hit a market with no fundamental floor much harder and faster than one where valuations were anchored to something real.
There’s no earnings yield or discount rate argument to slow the selloff. The same investors who bought the headline will sell the silence.
A big issue is that technically, overextended markets don’t require a negative catalyst to correct. They can simply run out of positive ones. A single disappointing data point, a stalled negotiation, or even just a week without a new deal announcement can be enough to trigger a repricing that looks wildly disproportionate to the news that caused it.
The upside is real if the tailwinds hold. But this is a market where the range of outcomes is unusually wide, the moves in either direction will be fast, and the margin for error — for timing, for positioning, for reading the next headline correctly — is razor thin.
