Instant Portfolio Builder: Biotech & Pharma Stocks

Use the Instant Portfolio Builder: Biotech & Pharma Stocks to compute the 10-year annualized returns of portfolios of randomly selected biotech and pharmaceutical stocks with ten or more years of price data at Yahoo! Finance. See the 53 pharmaceutical and biotech stocks.

To run the calculator, select the number of stocks in a portfolio and the number of portfolios to generate. The calculator selects stocks randomly using random numbers from the PHP mt_rand() function.

The stocks are equally weighted in a portfolio. For example, each stock in a 20-stock portfolio is weighted at five percent of the portfolio.

The calculator displays the 10-year annualized return for each random portfolio from highest to lowest. Click on a return for a portfolio to see the stocks included in it. In addition, the average return and standard deviation for all random portfolio returns are displayed.

And the 10-year annualized returns of the SPDR S&P 500 ETF (SPY) and the Health Care Select Sector SPDR Fund (XLV) are displayed for comparison.

Also, compare the calculator results with those from the Instant Rebalanced Portfolio Builder: Biotech & Pharma Stocks which assumes stocks change each year for a 10-year period.

All returns are based on weekly closing prices with dividends reinvested from Yahoo! Finance.
