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.

$339.45$806.83$1,274$1,742
2021-102026-09 · $1,218

Over 3 months from Sep 2026, roughly two-thirds of past moves landed between $979.78 and $1,514; nine in ten between $851.55 and $1,742.

Tested against this asset’s own history: across 248 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 $36,150 today, so the real (inflation-adjusted) return is +2706.6%.

Lump sum instead — $26,300 all at once in Nov 2004: $3,241,715 (+12225.9%) — lump sum came out ahead.

Worst timing — same monthly amount started at the all-time high (Apr 2026): $522.74 on $600 invested (-12.9%).

⚠ 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.
