Misreading misleading headlines: VIX edition

February 13, 2012

I was shocked to see the following bold headline this morning, as it describes something which did not actually happen: CBOE 'fear guage' drops 6% in Monday trading Let's be clear: the VIX is measured in percentage points.

Misreading misleading charts: Alaska edition

August 4, 2011

There's a headline making the rounds this morning that caught my eye because it seemed preposterous: "Apple Stock Helping the Alaska Permanent Fund More than Oil."

Misreading misleading charts

March 26, 2009

This chart caught my eye because it is potentially misleading (click to zoom).  It shows the year-over-year change in hotel occupancy rates, from 2001-2009. My first impression, on viewing the small chart, was that we haven't hit the low of the last recession.  But (as the box very clearly points out) the low of the […]
