Scenarios

Inflation — the same contributions merely keeping pace with CPI would be $35,908 today, so the real (inflation-adjusted) return is +3205.9%.

Lump sum instead — $26,200 all at once in Nov 2004: $3,778,873 (+14323.2%) — lump sum came out ahead.

Worst timing — same monthly amount started at the all-time high (Apr 2026): $482.27 on $500 invested (-3.5%).

⚠ 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.

It's a listed company categorised under information technology and semiconductors, with a market cap of about $70.0B.

It rates High Risk at 2.9/5, meaning several rated factors score badly, so this carries materially more risk than a typical holding.

Scoring well: sector / regulatory at 1.0/5.

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