The first quarter brought some long overdue volatility to equity markets. Indeed, the S&P 500 Index’s relatively modest decline of 0.8% belies the underlying tumult during the quarter. Markets started the year where they left off in 2017, with the S&P 500 Index gaining 5.7% in January and cruising to new all-time highs. However, things quickly changed in February as the S&P 500 Index declined 3.7% and snapped its longest monthly winning streak since 1959 according to CNBC.
