A Connecticut judge has settled a bitter feud over the estate of the late legendary blues guitarist Johnny Winter.

In the two years since the office-sharing company’s failed IPO, a new way to launch a stock on Wall Street has become fashionable: SPACs. Special purpose acquisition companies have been embraced by big institutions and small-pocketed investors alike. The goal is to use those millions of dollars to take a private company public without using the traditional initial public offering process that’s been around for decades. Management has a financial incentive to find an acquisition target — most often management receives a 20% stake in the newly public company. An exchange-traded fund consisting of SPACs and companies taken public through SPAC acquisitions, the Defiance Next Gen SPAC fund, jumped 55% between early November and mid-February.
