Stocks were indicated to open handily lower on Thursday, after a disappointing no-change stance from the Bank of Japan caused stocks to slide globally. Despite the prices on Thursday, the investors theme that has prevailed of late is the return to buying the dips. Just keep in mind that the S&P 500’s last value seen was about 17.8 times its forward 12-month price-to-earnings (P/E) ratio, after peaking at 17.9 last week.
