Soybeans, and soy derivatives have large amounts of natural estrogens. Interestingly enough, soy sauce is not a major source of phytoestrogens. Flaxseed, pulses, citrus fruits, wheat, licorice, alfalfa, fennel and celery also have fairly large amounts of natural estrogens. List of Sources: 1.
Market cap (as it is commonly referred to) is equal to the stock price multiplied by the number of shares outstanding. For example, a stock with a $5 stock price and 10 million shares outstanding/trading is worth $50 million ($5 x 10 million).
Thus, the stock price is a relative and proportional value of a company's worth and only represents percentage changes in market cap at any given point in time. Any percentage changes in a stock price will result in an equal percentage change in a company's value. This is the reason why investors are so concerned with stock prices and any changes that may occur since a $0.10 drop in a $5 stock can result in a $100,000 loss for shareholders with one million shares.
