Wall Street last week, a rare huge transaction, the parties to track who

Wall Street on Friday suddenly emerged unprecedented number of huge transactions (blocktrade), a total of $ 19 billion worth of shares were taken off, triggering market speculation may be a file hedge fund or Family office bankruptcy, and intends to liquidate billions of dollars parts. Investors are racking their brains to find out the identity of the sellers, while fearing that more similar deals will emerge this week, dragging down the broader market.

The mega-deals, which led to a total of $35 billion in value evaporating from major stocks ranging from mid-cap to U.S. media players, have been the subject of chatter in traders’ chat rooms from New York to Hong Kong. Quay, a portfolio manager at Switzerland’s Bellevue Asset Management, said the magnitude was the only one he had seen in his 25-year career.

Bloomberg Information reported that Goldman Sachs sold $6.6 billion worth of shares in Baidu, Tencent Music and Vipshop Holdings before the U.S. stock market opened on the 26th, and later sold a total of $3.9 billion in ViacomCBS, Discovery, Farfetch, Aiki and Heilongjiang.

For its part, the Financial Times reported that Morgan Stanley also sold $4 billion worth of shares earlier in the day and another $4 billion in the afternoon.

Mega-transactions (selling a large number of shares at an agreed-upon price outside the market) are common, but it is rare for stocks of this size and this many to show up for regular trading hours.

Bo, a senior vice president at Wealthspire Advisors, thinks this is unusual, “The question now is: Is the deal done? Is it over? Or will it continue on Monday and Tuesday, subjecting the market to another wave of huge trades?”

Wall Street is trying to identify the sellers behind these stocks. Fund managers initially thought the mega-deals were focused on mainland technology groups before the SEC took new measures that could force U.S.-listed mainland companies off the market, but as similar deals continue to pour in, the stocks being sold are no longer just mainland companies, so some managers think it could be large safe-haven funds or family offices that are in trouble.
