A strong risk-on sentiment has markets rebounding after last week's sell-off, but headwinds may still be on the horizon. Ben Emons says a combination of factors - including earnings, interest rate decisions, and inflation data - could trigger another dip. However, he believes the underlying psychology is still "buy the dip," especially with companies like JPMorgan Chase (JPM) making significant investments in national security and resiliency. Rare earths are also in focus, with names like MP Materials Inc. (MP) and USA Rare Earth, Inc. (USAR) seeing massive gains.
