Week to date, shares of home marketplace company Opendoor Technologies (NASDAQ: OPEN) were up 37.4% through Thursday's market close, according to data provided by S&P Global Market Intelligence, after investors jumped back into high-risk stocks. The stock has cratered from a high of $11.39 in the last year all the way to under $1 per share, but it has recovered on the hope that the housing market won't be as bad as feared. It certainly helps that investors are bidding up a lot of the tech stocks that have gotten crushed over the past year.
