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.

$108.17$162.01$215.85$269.69
2021-102026-09 · $168.18

Over 3 months from Sep 2026, roughly two-thirds of past moves landed between $150.61 and $187.8; nine in ten between $140.26 and $201.66.

Tested against this asset’s own history: across 219 past 3-month windows, the price actually landed inside the two-thirds band 73% 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 $31,268 today, so the real (inflation-adjusted) return is +201.4%.

Lump sum instead — $23,400 all at once in Apr 2007: $70,150 (+199.8%) — DCA came out ahead.

Worst timing — same monthly amount started at the all-time high (Feb 2025): $1,594 on $2,000 invested (-20.3%).

⚠ 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.

About T-Mobile US

T-Mobile US, Inc. is an American wireless network operator headquartered in Bellevue, Washington. Its majority shareholder and namesake is the German telecommunications company Deutsche Telekom. T-Mobile is the second largest wireless carrier in the United States, with 140 million subscribers as of September 30, 2025. (Wikipedia)

It's a listed company categorised under communication services and wireless telecommunication services, with a market cap of about $180.4B.

It rates High Risk at 2.8/5, meaning several rated factors score badly, so this carries materially more risk than a typical holding.

What pushes the score up: leverage / financial (4.0/5) and earnings quality (3.0/5).

Scoring well: liquidity at 1.0/5.

Not yet researched: concentration, governance. These are excluded from the score rather than guessed, so the real risk may be higher than what’s shown.
