A visualization of each time @APompliano has tweeted about "entering the new bull market"

out of a sample size of 15 (excluding today's call because it was only 2 hours ago), 10 of those tweets were followed by a red day (66.6%)

The average 7 day return, measured from the close of the day the tweet was made, is -2.58%, with only 3 tweets resulting in positive 7-day results

I can continue running more numbers, but the TL;DR is "pomp, please for the love of god shut the fuck up."

Conversely, just market sell every time. It's a profitable strategy, although I'd prefer more data points before running a significant amount of money on the strat.
