Back-Up-The-Truck, boyz?? LOL...

Maybe. But... nahhh. Not for me. Not yet.
For most folks doing things gradually keeps risk closer to their tolerance. You don't want to be chasing it up in the FOMO frenzy, so starting to nibble a bit early, and patiently enduring a tolerable drawdown should one occur, means you at least have some skin in if the correction takes you by surprise. I think we are about half the fundamental PQ=MV price right now, so a correction seems inevitable, eventually, unless the dnm economy suddenly contracts to match. I allocate a % of powder to limit bids increasing in size all down the book, and a % of disposable income to periodic buys, under such circumstances. But yeah, the staircase has not confirmedly reversed yet.
