Question 1

How much would $1,000 invested in Amazon in 2000 be worth today?

Accepted Answer

$1,000 invested in Amazon at the start of 2000 (around $65 pre-split, or roughly $3.25 split-adjusted after the 20-for-1 split in 2022) would be worth well over $60,000 today — an approximate 60x return over 25 years, or about 18% annualized. This ignores dividends (Amazon doesn't pay any) and taxes. The exact number depends on the precise purchase date, since Amazon traded as high as $107 pre-split at the peak of the dot-com bubble and as low as $6 after the crash.

Question 2

How do I calculate what my past stock investment would be worth today?

Accepted Answer

Start with the historical price on your purchase date, divide your investment amount by that price to get your original share count, and multiply by the cumulative split ratio for every split that has happened since. Multiply the resulting split-adjusted share count by today's price to get your position's current value. The math is straightforward but tedious to do by hand across multiple splits — this calculator handles it automatically for every covered company.

Question 3

Which stocks have delivered the best long-term returns?

Accepted Answer

Over the last 30 years, top performers include NVIDIA, Amazon, Apple, Netflix, Monster Beverage, and Domino's Pizza — several of which have compounded at 20–35% annualized over multi-decade stretches. Over shorter windows, the leaderboard rotates heavily: 2010s tech (FAANG), 2020s AI infrastructure (NVIDIA, Broadcom), and various biotech and semiconductor names have all had their moment. Past leaders rarely repeat, which is why diversification beats trying to pick the next 10-bagger.

Question 4

Why do split-adjusted prices matter for calculating historical returns?

Accepted Answer

Because raw historical prices are misleading. Apple traded around $700 in 2014 and $232 today — without split adjustment, that looks like a decline. Apply the 7-for-1 (2014) and 4-for-1 (2020) splits and the true split-adjusted 2014 price is closer to $25, making today's $232 an 800%+ gain. Any honest historical return calculation must split-adjust; every calculation on this page does that automatically.

Question 5

Is it too late to invest in stocks that have already gone up 10x?

Accepted Answer

Not necessarily. Amazon, Apple, and Microsoft were all up 10x from IPO by the mid-2000s and have since delivered another 20–50x on top of that. The relevant question is not 'how much has it already risen?' but 'is the underlying business still growing, and is the valuation reasonable relative to that growth?' Historically expensive winners can keep compounding for decades; historically cheap losers can stay cheap. Use this tool for context, not as a signal on its own.
