I would hope that people reading the link would understand the definition of ADJUSTED CLOSE. The adjusted close of $24.19 is the price of Intel stock adjusted for the dividend paid over the last 10 years.
$29.81 was the close and the adjusted close $24.19 compute $5.62 in dividends in the past 10 years. The "lame dividend" argument is not too lame if Intel was bought in the last couple years at prices below $20 or even if its sole purpose is for income.
People follow stocks and participate in the discussions for personal profit. The only other reason that I can think of is for entertainment. Are there any other reasons?
It really does not matter what the Intel price was 10 years ago does it? It matters what the Intel price is tomorrow, next month, next year, ... and what the prospects are for tomorrow. It is hard to make any money on the past.
I buy the stock and keep a core position. Sell puts after a sell off and sell covered calls (buy-writes) after a run up. It seems to be a steady predictable source of income. The share price seems to be reacting (not controlled) to option activity (strangles and straddles) that seemed to be timed to the dividend payments.
