Bitcoin to the moon, the rise of special purpose acquisition companies (SPACs), and chat room trading all the rage – it can feel like 2021 all over again. The Federal Reserve's interest rate cut signal in December sparked a furious rally to record levels, unleashing animal instincts that have been fueling similar speculative activity from the depths of the pandemic. “Animal instincts are reviving,” Michael Hartnett, chief investment strategist at Bank of America Global Research, said in a phone interview. The most glaring example is the rise in distressed debt in emerging markets, which has risen about 25% from its October lows, he said. “When people want to play it safe, they don't buy distressed emerging market debt,” Hartnett said. “Nigeria and Argentina are not the places, but they are now.” “The catalyst for all of this is the Fed’s pivot.” Today's conventional wisdom pushing investors into some of the riskier parts of the market goes like this: Inflation will fall to the central bank's 2% target while the economy will avoid recession before a series of interest rate cuts arrive. These combined hopes have pushed the S&P 500 higher for four straight months, setting consecutive records above the 5,000 level. The Nasdaq Composite just surpassed its 2021 record close on Thursday.

I need to wake up every morning to see what stock could go up 50% by Friday,” he wrote. “US stocks have entered a period of euphoria.” Even those pandemic wonders known as SPACs , or special purpose acquisition companies, are showing signs of recovery after suffering from a drought over the past two years.There were 33 pending SPAC IPOs in just two months of 2024, more than the number in all of 2023, according to SPAC Research. Digital investment platform Webull plans to go public through a SPAC deal that values the company at a whopping $7.3 billion. “Animal instincts don't necessarily start with the biggest animals in the jungle,” Quincy Crosby, chief global strategist at LPL Financial, said by phone. She pointed to a wave of mergers and acquisitions between biotech and pharmaceutical companies as further evidence. Certainly others believe the market rally was justified by enthusiasm for artificial intelligence, and the contribution it is likely to make to future corporate profits.
