CNBC's Jim Cramer said the market has become "incredibly overconfident" following the news of a temporary ceasefire between the U.S. and Iran, which caused a massive rally in stocks this week. Cramer warned that the idea of everything going right in the Middle East is "a real stretch" and that investors should not make sudden moves with the market in such a perilous state.

Why it matters

The U.S.-Iran conflict has been a major source of market volatility since early March, so the temporary ceasefire provided a brief reprieve. However, Cramer cautions that the situation remains tenuous, and investors should not become overly optimistic given the uncertainty around the geopolitical tensions.

The details

The S&P 500 closed Friday up 3.6% week to date, fueled by President Donald Trump's two-week pause on Iranian strikes announced late Tuesday. The Nasdaq Composite and Dow jumped 4.7% and 3%, respectively, over the past five sessions as well. Cramer said the market has become "incredibly overconfident" given the fragile nature of the ceasefire, warning that Iran can "shut down the most important commercial waterway on earth in a heartbeat."

  • On Thursday, Trump warned that Iran "better stop now" if it's charging fees to oil tankers going through the Strait of Hormuz.
  • Two weeks ago, the market was "on tenterhooks" due to the U.S.-Iran conflict, leading to an oversold condition.

What’s next

Cramer said investors should not make any sudden moves with the market in such a perilous state and all the war uncertainty. He advised that there is no systemic risk that could bring down the entire market, but the overconfidence and overbought nature of the market are not conducive to further gains.

The takeaway

This case highlights the fragility of the market's recent rally, which was fueled by optimism around a temporary ceasefire between the U.S. and Iran. Cramer's warnings underscore the need for investors to maintain a cautious and measured approach given the ongoing geopolitical tensions and the potential for renewed volatility.
