You’re right, this chart doesn’t factor in stock splits. Since February 1997, Intel has undergone three 2-for-1 splits, so a $10K investment back then would now be worth around $80K.

If we adjust for inflation, that initial $10K in 1997 would be equivalent to about $19K in today’s dollars. So, overall, the investment has experienced roughly 4x growth over the last 27 years.

Potentially, we should also account for dividends paid during this period of time.

Thanks for bringing this up!
