There’s a storm coming in the investment industry. Some investors already feel the pain of that storm. But according to Angel investor Shervin Pishevar, the worst is yet to come. Pishevar is the man who predicted Uber would be a giant. He invested $21 million in Uber, and that injection of cash gave Uber the financial backing it needed to expand. But Uber isn’t the only investment that made Shervin Pishevar an investment cult figure in Silicon Valley. He also invested in Dollar Shave Club, Airbnb, Warby Parker, and Postmates. That’s some of the winners Shervin helped get to the top.

Pishevar started Sherpa Capital so he could continue helping startups get their feet on the ground. Shervin had more than $650 million in assets under management when he resigned in December 2017. But in February 2018, Shervin Pishevar surfaced on Twitter. His 21-hour tweet storm didn’t mean too much when he posted more than 50 tweets about a financial collapse. But now that the stock market is turning some investors into whimpering losers, Pishevar’s tweet predictions are the talk of the investment industry.

Mr. Pishevar said the stock market would tank in 2018. He said the market would give back all its gains. And that’s exactly what’s happening. The Dow Jones Industrial Average is in negative territory for the year. Investors see the bear market taking shape faster than they expected. But Shervin Pishevar knew the market would turn rookie investors into frantic crybabies with no backup plan months ago. His tweet about the bond market yields seems to be taking shape as well. The 2-year bond yield may catch up with the 10-year yield in 2019, and that possibility has seasoned investors worried.

And to make investment matters worse, Pishevar predicted no asset class will keep investors safe in 2019. Even gold and Bitcoin investors are looking for safe havens, according to recent financial news reports. Some investors want to hear more from Shervin Pishevar. That may happen in 2019 now that his tweetstorm prompted investment around the world to follow him on Twitter. They want to know where they should put their money next year.
