The stock market will go down 80% 'when this is over,' says bearish investor Mark Spitznagel

By Laila Maidan
Spitznagel still believes we haven't entered the main event and the recent stock-market plunge is just a 'trap'
One of Wall Street's most notoriously pessimistic - and successful - investors, Mark Spitznagel, said the stock-market plunge that's followed President Donald Trump's tariff rollout isn't the epic market crash he has been calling for, but rather the turmoil along the way to the big event.
"I expect an 80% crash when this is over. I just don't think this is it. This is a trap," he wrote in commentary to MarketWatch on Monday, adding that when the real crash happens, investors will know it.
Spitznagel is the founder and chief investment officer of hedge fund Universa Investments, which employs a strategy that aims to take positions that will benefit from rare, unpredictable but highly impactful events. It's known as a "Black Swan" fund - a term to describe such events popularized by scientist, author and former options trader Nassim Nicholas Taleb, who was influential in the firm's strategy.
Universa made headlines in the first quarter of 2020 for returning 4,144% as the market crashed in March from fears of the COVID pandemic. Spitznagel told MarketWatch that Universa is still trading this market like a crash even though he's not convinced one has arrived.
"This is another selloff to shake people out. This isn't Armageddon. That time will come as the bubble bursts," he wrote. "This is a most contrarian view right now. Promise."
Stocks were off session lows but posting losses in a wildly volatile session Monday that saw swings from sharp losses to sharp gains and back again. The Dow Jones Industrial Average DJIA was down more than 200 points, or 0.57%, while the S&P 500 SPX slightly recovered by 0.35%, and the Nasdaq Composite COMP was down 0.84%. The S&P 500 fell a cumulative 10.5% on Thursday and Friday after President Donald Trump last week unveiled sweeping tariff measures. The S&P 500 and other major indexes saw their steepest two-day selloff since March 2020, when stocks plunged as the COVID-19 pandemic forced an economic shutdown.
Spitznagel has been calling for a bigger crash - one that would be the worst since 1929. The investor emphasized he isn't in the business of predicting the timing of market crashes. However, he has previously voiced concerns over mounting U.S. debt, which he sees posing a key risk to markets.
In 2024, he warned investors about not getting caught off guard when the stock market does turn for the worse, and end up being the "sucker" that sells when the market is down and buys when it's up. He advocated having positions agnostic to market turmoil - a difficult ask for the average person.
"We've had our clients riding this bull market for years," Spitznagel wrote on Monday. "All the doom and gloomers think it's over and they have this figured out. Take it from a professional doomer, they don't. And they definitely don't have the right position for it."
In a 2023 interview with Fortune, he noted that retail investors could ride out storms without needing to resort to complex trading strategies by simply buying low-cost, broad index funds, and even adding to their positions when the market is down. The key for retail is to not overextend their exposure to a point of being forced to sell at a bad time in the market.

“史诗级崩盘”还在路上 黑天鹅经理人:美股将暴跌80%
川普关税风暴席卷全球股市,美股本周首个交易日剧烈震荡,不过以悲观着名的华尔街“黑天鹅”基金经理人史匹兹纳格尔(Mark Spitznagel)7日表示,他认为这波跌幅还没达到他预期的“史诗级崩盘”程度,他认为最终股市将暴跌达80%。
根据市场观察网站(Market Watch)报导,史匹兹纳格尔表示,当真正的崩盘发生时,投资人自然会知道,而他认为在川普宣布关税后的市场震荡只不过是大事件发生前的波动,真正的好戏还没上场。史匹兹纳格尔预期,“当一切结束时,股市将崩盘80%,我不认为就这样而已,这是一个陷阱。”
美股周一剧烈波动,先是大幅下跌,又从盘中低点大幅上涨,但随后又出现大幅下跌。史匹兹纳格尔表示,此次只是“另一次抛售”,目的是让投资人摆脱困境。他说,“这还不是世界末日,当泡沫破裂后才是,这种观点现在非常逆风,相信我。”
史匹兹纳格尔是对冲基金Universa Investments的创始人兼首席投资长,该基金采取的策略是从罕见、不可预测但影响巨大的事件中获利,又被称之为“黑天鹅”基金。该基金曾在2020年3月市场因新冠疫情而崩盘之际,逆势创下4144%的超高回报率而声名大噪。
史匹兹纳格尔过去不断警告股市将发生更大规模的崩盘,且将是自1929年大萧条以来的最严重股灾。他强调,他并不负责预测市场崩盘的时间点,但他先前曾对美国不断增加的债务表示担忧,认为这会带来严重的市场风险。
