A $576 Billion Stock-ETF Juggernaut Hit by Extreme Dislocations
In another sign of the frantic trading on Wall Street, the $576 billion SPDR S&P 500 ETF Trust, or SPY, closed roughly 90 basis points above its net-asset value on a day when it surged 10.5% — the most in 16 years — data compiled by Bloomberg show. For comparison, SPY's average dislocation to its NAV over the past decade is just a fraction of a basis point. The early Covid months of 2020 also saw it trade above or below its net-asset value, though none of those gaps were as wide as where Wednesday's ended up.
Traders frantically covering bearish trades likely contributed to the flood of capital into SPY that afternoon. The fund, which on average has traded roughly 56 million shares a day over the past year, is known for its liquidity. But on Wednesday, closing-auction volumes were running roughly 300% higher than usual and likely a factor in driving up the premium, according to Matt Bartolini, head of SPDR Americas Research at State Street Global Advisors.
'That's just a function of the ETF, of SPY — it's a significant liquidity vehicle for a large swath of traders and investors to rotate into,' he said in an interview. 'Given the sizable moves that we saw yesterday intraday, but also heading into the close, there was just a large balance of buy orders coming in to mark the close that then pushed the price up above.'
It's important to remember the context in which the frenzied trading happened: market moves have been extreme in recent days, he added. 'It's a feature of SPY to have the ability to absorb that much liquidity in two-way trading volumes.'
The S&P 500 on Wednesday staged a historic rebound after President Donald Trump said he would pause tariffs on some trading partners. More than 241 million shares of SPY changed hands.
'Yesterday's moves were so extreme that even the world's most liquid ETF was not immune to an impact as the closing auction traded well above its fair value,' said Dave Mazza, chief executive officer at ETF issuer Roundhill Investments. 'When SPY sees moves like this, you know it's a wild day in the markets.'
His calculations show that some 8 million shares ended up paying about $5 above the closing-auction price.
Trump's disruptive trade plans are challenging the most liquid investing tools in the world as fresh volatility hits Wall Street. Stocks resumed their plunge Thursday.
'I think there is a good likelihood you'll see some elevated dislocations in SPY and other ETFs — it's not uncommon in panicked markets,' said Bloomberg Intelligence's Athanasios Psarofagis. 'But that said, ETFs are handling this phenomenally.'
Still others had another theory to offer: Traders frantically covering bearish trades likely contributed to the flood of capital into SPY on Wednesday afternoon, according to Ling Zhou, head of equity derivatives strategy at TD Securities.
Investors that were net short equities or short options positions needed to chase the rally after Trump's tariff pause announcement, he said.
'This speaks to how much people got hurt on their shorts on the rally yesterday,' Zhou said. 'Liquidity worsened and investors needed to hedge shorts via SPY.'

Fed rate cuts could spark a new stock bubble, SocGen says. Here's the level to watch in the S&P 500.
US stocks risk entering a bubble in the coming months, SocGen strategists say. Fed rate cuts risk adding further fuel to an already record-setting rally in stocks. The bank is eying a key level for the benchmark index that would signal the risk of a bubble. The market sees about an 85% chance that the Federal Reserve delivers a rate cut in September — but doing so could put the stock market on track to enter bubble territory in the coming months. That's according to strategists at Société Générale, who said they saw the possibility that the S&P 500 becomes overheated sometime in the next year. The level of the S&P 500 they're warning investors to look out for is 7,500. That implies a 19% gain for the benchmark index, and would signal that the speculative mania has reached bubble proportions. Here's what they're eyeing. 1) Fed rate cuts. Investors are widely expecting the Fed to cut interest rates, with the odds of a September rate cut spiking after the July jobs report was unexpectedly weak last Friday. According to the CME FedWatch tool, the market-priced probability of a 25-basis-point rate cut next month has jumped to 87%, up from 63% a week ago. "Gradual rate cutting could add to the positive effect of cyclical data, while aggressive Fed rate cuts to the terminal rate could drive a market valuation bubble," strategists wrote. 2) Bullish runway. Fed rate cuts are also adding to an already-positive environment for stocks, strategists said, pointing to factors like higher growth, healthy debt-taking in the private sector, and corporate activities improving from lows earlier in the business cycle. "Strong returns from the S&P 500 over the past three months have borne out our US outlook, crisis of confidence is short-term," strategists wrote. The S&P 500 reaching 7,500 next year would imply valuations similar to levels seen during the peak of the dot-com bubble, according to SocGen's analysis. The bank's base case is for the S&P 500 to land around 6,900 by the end of next year, implying a 9% gain from current levels. Chatter about a potential stock market bubble has been percolating around Wall Street in recent months, given the S&P 500's record-breaking rally. Stocks have quickly rebounded since bottoming on April 8 following Trump's tariff announcements, with the S&P 500 up 28% since then. Read the original article on Business Insider

Company advised by Trump sons said it hoped to benefit from fed money, then took it back
NEW YORK (AP) — A public document filed by a company that just hired President Donald Trump's two oldest sons as advisers included a sentence early Monday that said it hoped to benefit from grants and other incentives from the federal government, which their father happens to lead. But when The Associated Press asked the Trump family business about the apparent conflict of interest, the document was revised and the line taken out. Eric Trump and Donald Trump Jr. are getting 'founder shares' worth millions of dollars in New America Acquisition 1 Corp., a company with no operating business that hopes to fill that hole by purchasing an American company that can play 'a meaningful role in revitalizing domestic manufacturing,' according to to the filing. The president has geared his trade policy toward boosting manufacturing in the U.S. The original version of the securities filing said the target company should be 'well positioned' to tap federal or state government incentives. That reference was taken out of the revised version of the filing. The Trump Organization didn't reply to a question about whether New America still planned to benefit from government programs or why the line was cut. But the outside law firm Paul Weiss that helped prepare the document sent an email to AP saying it was 'mistake' made by 'scriveners,' an old term for transcribers of legal papers. Kathleen Clark, an expert in government ethics, said any excuses are too late because the Trumps had already tipped their hand. 'They just deleted the language. They haven't committed not to do what they said earlier today they were planning to do," said the Washington University law professor and Trump critic. "It's an attempt to exploit public office for private profit.' New America is what's know as a special purpose acquisition company, or SPAC. It's a publicly traded company that exists solely to use its funds to acquire another company and take the target public. New America plans to raise money by selling stock on the New York Stock Exchange at $10 a share. That will hand the two Trump sons a total of $5 million in paper wealth on the first day of trading. The company hopes to sell enough shares to raise $300 million, which it then plans to use buying a yet unidentified manufacturer. A press release issued by New America saying it was focused on 'American values and priorities." It made no mention of the aim to get government incentives. The filing to New America's potential new investors to Securities and Exchange Commission was explicit about what it was looking for in target company. It said, among other things, it would that can ride 'public policy tailwinds" by benefiting from federal or state 'grants, tax credits, government contracts or preferential procurement programs.'

Trump Administration Posts Guidance on Tariff Rollout
(Bloomberg) -- President Donald Trump's expanded reciprocal tariffs will not apply to any products loaded onto a vessel for transport into the US before 12:01 a.m. New York time on Thursday, according to guidance issued by US Customs and Border Protection. PATH Train Service Resumes After Fire at Jersey City Station Chicago Curbs Hiring, Travel to Tackle $1 Billion Budget Hole Seeking Relief From Heat and Smog, Cities Follow the Wind Mayor Asked to Explain $1.4 Billion of Wasted Johannesburg Funds The notice, posted by the federal government on Monday, outlines implementation of the tariffs Trump announced last week, which are expected to ratchet up levies on dozens of trading partners. Expected exemptions for products under the US-Mexico-Canada free trade agreement negotiated by the president during his first term are included in the document, as are exemptions for relief items like food, clothing and medicine set to be distributed as aid. So is the president's threatened penalty of a 40% tariff on goods deemed by the federal government to be transshipped to avoid country-specific duties. Taken together, the average US tariff rate will rise to 15.2% if rates are implemented as announced, according to Bloomberg Economics. That's up from 13.3% earlier and significantly higher than the 2.3% in 2024 before Trump took office. Trump's country-based tariffs have been billed as the centerpiece of his plan to shrink trade deficits and pressure companies to shift manufacturing jobs and investment to the US. Trump previously delayed his so-called reciprocal tariffs, first announced in April, to allow time for negotiations as nations sought to obtain better trade terms. Some countries, including Switzerland and India, are still attempting to negotiate deals to lower their duties ahead of Thursday's deadline. Trump is expected to unveil separate tariffs on imports of pharmaceuticals, semiconductors, critical minerals and other key industrial products in the coming weeks, meaning ongoing uncertainty for companies and investors. And on Monday, he also threatened to impose 'substantially' higher levies on Indian exports to the US over New Delhi's purchases of Russian oil. While his tariffs are already bringing in billions in revenue for the US government, the longterm economic impacts remain unclear, with critics saying they will raise costs for US consumers and businesses and exacerbate inflation.
