ORLANDO, Florida, Feb 5 (Reuters) - "Bouncebackability."

This Britishism is generally connected with cliche-prone soccer supervisors trumpeting their groups' capability to respond to beat. It's not likely to discover its method throughout the pond into the Wall Street crowd's lexicon, however it completely sums up the U.S. stock exchange's resilience to all the problems, shocks and everything else that's been thrown at it recently.

And systemcheck-wiki.de there have actually been a lot: U.S. President Donald Trump's tariff flip-flops, extended appraisals, severe concentration in Big Tech and the DeepSeek-led turmoil that just recently called into question America's "exceptionalism" in the global AI arms race.

Any among those concerns still has the possible to snowball, causing an avalanche of selling that could press U.S. equities into a correction or even bear-market territory.

But Wall Street has become remarkably durable since the 2022 rout, particularly in the last six months.

Just take a look at the synthetic intelligence-fueled turmoil on Jan. 27, stimulated by Chinese startup DeepSeek's revelation that it had established a big language design that might attain comparable or better results than U.S.-developed LLMs at a fraction of the cost. By lots of steps, the marketplace move was seismic.

Nvidia shares fell 17%, slicing almost $600 billion off the company's market cap, the most significant one-day loss for any company ever. The worth of the wider U.S. stock market fell by around $1 trillion.

Drilling deeper, analysts at JPMorgan found that the thrashing in "long momentum" - basically buying stocks that have been performing well just recently, such as tech and AI shares - was a near "7 sigma" move, or 7 times the basic discrepancy. It was the third-largest fall in 40 years for this trading strategy.

But this epic move didn't crash the market. Rotation into other sectors sped up, and around 70% of S&P 500-listed stocks ended the day higher, indicating the more comprehensive index fell only 1.45%. And purchasers of tech stocks quickly returned.

U.S. equity funds brought in nearly $24 billion of inflows recently, innovation fund inflows struck a 16-week high, and momentum funds drew in positive flows for a fifth-consecutive week, according to EPFR, the fund streams tracking company.

"Investors saw the DeepSeek-triggered selloff as an opportunity instead of an off-ramp," EPFR director of research Cameron Brandt wrote on Monday. "Fund flows ... suggest that numerous of those investors kept faith with their previous presumptions about AI."

PANIC MODE?

Remember "yenmageddon," the yen carry trade volatility of last August? The yen's sudden bounce from a 33-year low against the dollar stimulated fears that investors would be forced to offer properties in other markets and countries to cover losses in their big yen-funded bring trades.

The yen's rally was severe, on par with past monetary crises, and the Nikkei's 12% fall on Aug. 5 was the most significant one-day drop given that October 1987 and the second-largest on record.

The panic, if it can be called that, spread. The S&P 500 lost 8% in 2 days. But it vanished rapidly. The S&P 500 recouped its losses within two weeks, and the Nikkei did likewise within a month.

So Wall Street has actually passed two big tests in the last six months, a duration that consisted of the U.S. presidential election and Trump's go back to the White House.

What explains the durability? There's no one obvious response. Investors are broadly bullish about Trump's economic program, the Fed still seems to be in relieving mode (for now), the AI craze and U.S. exceptionalism stories are still in play, and liquidity abounds.

Perhaps one key chauffeur is a well-worn one: the Fed put. a lot of whom have spent a great piece of their working lives in the era of extraordinarily loose monetary policy - may still feel that, if it truly comes down to it, the Fed will have their backs.

There will be more pullbacks, and risks of a more extended decline do seem to be growing. But for now, bytes-the-dust.com the rebounds keep coming. That's bouncebackability.
