1. Wall Street is battling over whether scorching-hot tech stocks are too expensive. The answer varies, depending on which valuation metric one uses.
2. One of history's most reliable stock-trading strategies is struggling. Value investing provided consistent gains for the better part of seven decades, but has faltered during the ongoing economic cycle.

4. Traders are cranking up their bets against Snap. They haven't been this bearish on the stock since the period immediately following its IPO. Snap has been drawing the ire of analysts across Wall Street because of concerns over user growth.
