Price History

The shaded fan is where this price has historically travelled over the months after a close like today’s. It is not a forecast: it has no view on direction, only on distance.

$83.15$850$1,617$2,384
2021-102026-09 · $1,651

Over 3 months from Sep 2026, roughly two-thirds of past moves landed between $1,321 and $2,064; nine in ten between $1,144 and $2,384.

Tested against this asset’s own history: across 337 past 3-month windows, the price actually landed inside the two-thirds band 66% of the time. The gap from 68% is the model’s error — real returns have fatter tails than the maths assumes, so the band gets breached more often than it claims.

Scenarios

Inflation — the same contributions merely keeping pace with CPI would be $53,245 today, so the real (inflation-adjusted) return is +9337.4%.

Lump sum instead — $35,200 all at once in Jun 1997: $3,720,206 (+10468.8%) — DCA came out ahead.

Worst timing — same monthly amount started at the all-time high (Jun 2026): $385.63 on $400 invested (-3.6%).

⚠ Price returns only — dividends are not included. This understates the true return of dividend-paying shares, and any comparison against crypto (which pays no dividends) is biased against equities by roughly the dividend yield, compounded.
