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).
That would make the total investment $65,000 and the average stock price $32.50. However, this is not dollar cost averaging -- it is simple averaging. The average cost of the stock will not trend towards the current market value if you do not remain consistent in your investment strategy. Using dollar cost averaging, a person would invest a fixed amount -- say $33,000 per interval.
