Warning: [[irrational exuberance]] gave lots of data against this /tactic/ — Invest at every correction or crash, invest in bigger amounts than you have recently done in normal times. If decline continues, then decide whether to buy-n-Forget or invest more.

ETF quickGrab: buy-low +! due diligence is a more concrete plan.

— J4: ECR compound return .. widely accepted, even on non-U.S. markets [1].
This perception basically assumes that after every decline, perhaps after a few years [1] of zigzag, market would eventually transition to a “fast_window”, where annual return stays above average for months or years.

Some traders focus on the shorter horizon and target to capture a few months of fast_window. In contrasts, authors (big influence on me), financial advisors, financial planners, bank staff … focus on a longer horizon of a few years to a decade. But regardless of horizon, all of them agree on one thing — the fast_window.

— J4: DCA robot.. See my blogpost on DCA
j4: DRIP robot is related

DCA and DRIP assume that even after a market /rally/, it’s not unwise, not risky, to let the robot continue investing _small_ amounts.

— [1] Warning: this analysis only applies to U.S. equities. Non-U.S. markets can experience a long trough before (hopefully) entering a fast_window.
