Scenarios

Inflation — the same contributions merely keeping pace with CPI would be $40,029 today, so the real (inflation-adjusted) return is +2300.0%.

Lump sum instead — $28,500 all at once in Dec 2002: $2,332,617 (+8084.6%) — lump sum came out ahead.

Worst timing — same monthly amount started at the all-time high (Jun 2026): $293.59 on $300 invested (-2.1%).

⚠ 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 Seagate Technology

Seagate Technology Holdings plc is an Irish-domiciled data storage company. It was incorporated in 1978 as Shugart Technology and commenced business in 1979. Since 2010, the company has been incorporated in Dublin, Ireland, with operational headquarters in Fremont, California, United States. (Wikipedia)

It's a listed company categorised under information technology and technology hardware, storage & peripherals, with a market cap of about $199.0B.

It rates High Risk at 3.0/5, meaning several rated factors score badly, so this carries materially more risk than a typical holding.

What pushes the score up: earnings quality (5.0/5) and market / volatility (4.7/5).

Scoring well: sector / regulatory 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.

Ratings summarise sourced facts against fixed rules — not investment advice, and no substitute for your own diligence.
