For our most recent M6 competition submission (Apr 24), our model said $VXX had over 60% chance of placing in the top quintile of performance among all US stocks + ETFs. I thought that couldn't possibly be right, so I fudged the numbers down to 45%.🤦‍♂️

There were ~1,000 users when I joined my #MastodonSocial server (mstdn.ca) about a week and a half ago. There are now nearly 20,000 users. The poor server admin is going nuts trying to scale resources.
