Best Finance Tweets of the Year: 2015

“The ephemerality of good tweets is a feature, not a bug,” Matt Levine tweeted in June. “It reminds us that life is fleeting and wit is worthless.”

The average tweet has about 15 minutes to be seen and shared before it gets buried under a stream of newer tweets, social media consultants say. But over the past year, a few of them stuck out.

Here, in chronological order, are some of our favorite tweets from 2015:

 Janus manager Bill Gross called for shorting 10-year bunds. But when his fund subsequently fell 2.5% after he made the trade, he chalked up the loss to poor execution.

Gross: German 10yr Bunds = The short of a lifetime. Better than the pound in 1993. Only question is Timing / ECB QE
