# 100-Day Reading Sharing Plan — Day 61

$Cleveland Cliffs(CLF.US) $Novo Nordisk AS(NVO.US) $Amazon(AMZN.US) Amazon has fallen for nine consecutive days, which I didn't expect. I'll continue holding.

"A Random Walk Down Wall Street"

1\. Albert Einstein once described compound interest as "the greatest mathematical discovery of all time."

2\. There is a useful rule called the "Rule of 72" that allows you to easily know how long it will take for your money to double. Divide the number 72 by the interest rate you receive, and you'll get the number of years it takes for your money to double.

3\. The higher a stock's dividend growth rate and earnings growth rate, the higher the price a rational investor should be willing to pay for it.

4\. Rule 2: All else being equal, the higher the proportion of a company's earnings paid out as cash dividends, the higher the price a rational investor should be willing to pay for its stock.

5\. There is a famous theory that states if a company's stock price (or its total annual return including dividends) is more volatile relative to the overall stock market, then the risk of that company's stock is greater.

Today is still the first day.
