# Small Caps Surge 2.16% Amid Geopolitical Tensions, DIA Up 1.77%

## The Take
- Monitor geopolitical events and potential market manipulation; consider diversifying into small caps for potential outperformance amid volatility.

_Geopolitical risks and insider trading probes weigh on sentiment as small caps outperform and energy markets remain volatile._

The global macro picture is shifting. Small caps led the market higher, with the IWM jumping 2.16%. The DIA also showed strong performance, gaining 1.77%. The SPY advanced 1.21%, while the QQQ climbed 1.31%. These gains occurred amidst escalating geopolitical tensions related to Iran and renewed concerns about potential insider trading related to energy markets.

Rep. Sam Liccardo is calling for an investigation into suspicious trading activity in oil and S&P 500 E-mini futures ahead of President Trump's announcements regarding Iran. The timing of these trades suggests potential insider knowledge, raising concerns about illicit trading practices. Simultaneously, Iran has tightened control over the Strait of Hormuz, citing U.S. interference with shipping, which has already impacted vessel routes and added to existing supply chain anxieties. Parliament speaker Mohammad Bagher Ghalibaf stated that "With the continuation of the blockade, the Strait of Hormuz will not remain open."

These geopolitical factors are contributing to volatility in energy markets, which are already influenced by supply-demand dynamics. The U.S. military has reported immediate effects on shipping patterns, with vessels being rerouted due to the blockade. While Canadian stocks such as Celsius, Canadian Natural Resources, and Canadian Pacific Kansas City are being highlighted by some analysts, the broader market focus remains on the interplay of geopolitical risks and their impact on global trade and investment flows. 

Macro regimes don't change overnight—but when they do, it matters.
