WHAT TO DO NOW: The market cave-in continues, with some sacred cows and resilient stocks catching up on the downside now. The trend clearly remains down, and while we’re not craving more cash (69% coming into today), have only smaller positions and see some legitimate oversold signs out there, we’re also not going to just hold and hope with things that are caving in. Tonight, then, we’ll sell the rest of our ProShares S&P 500 Fund (SSO) and one-third of what we have left in Uber (UBER), which will leave us with just over three-quarters of the portfolio on the sideline. Details below.
