A series of earthquakes were registered under Iceland's Katla volcano over the past couple of days. Judging by the depth of some of the earthquakes, fresh magma is making its way upward.

ââThinking that in a low-inflation environment is dreaming,â he said.â. Beyond that, the long-term data for the stock market points to that 7% number as well.

The log return for the year is the sum of the daily log returns. The log return for the year for the S&P is 12.8% (the data are in percent already).
