I'm still in the game at age 50.
Engineers are allowed to be eccentric, yes?
Accordingly, I would like to introduce the "Holiday Method" of investing. Nothing else seems to be working.

Today, on St Patrick's Day as it worked out, I did my first stock MF buy since I FIREd in 2007. I'm hoping the luck o' the Irish will be with me. I am part Irish.

The followup DCA will commence on April 1st, which is my FIRE anniversary.
I was going to wait until June to restart my stock MF DCA, for a different reason than market behavior. But what the heck, huh? The sale won't last forever.
