How to measure the returns on portfolio
For adding and withdrawals during a year the period of retention of a return for the portfolio is calculated in the following way:
Interest + Dividends + Capital earnings + Not expected capital earnings
Retention period = Initial investment + [New Funds x (# of Months in Portfolio / 12)] – [Funds
Withdrawal x (# of Months in Portfolio / 12]
For instance let’s imagine that a portfolio was started with $110,500 at the beginning of the year, received dividends for $8,600, and profits over capital for $12,000, but suffered an unexpected loss for $6,000 during a year. New funds for $10,000 were added at beginning of the month of April and an amount of $4,000 was withdrawn on October. The portfolio had an annual return of 12.44%
8,600 + 12,000 – 6,000
Retention period = 110,500 + 10,000 (9/12) – 4,000 (2/12) = 12.44%
This portfolio earned 12.44% of return before taxes, and can be compared with a comparable benchmark index for the same period of time.
Return as to how the Stock Market Index prices it
An unknown number of stock market indexes have different market prices, and you can use them in the following way:
- To determine the stock market happenings
- As a reference for comparing your portfolios and mutual funds individual performance
- As a tool to project future business fields
These market indexes only take a glance in each stock price operations. Even so you should understand the relation between index and individual stocks before getting into the game.
For example a panic attack is not necessary when Dow Jones Industrial Average falls 150 points any given day, neither should you order Champaign for all the neighborhood when NASDAQ Index raises 40 points. Normally, the different stock market indexes fluctuate from up to down as a group by much or few amounts in difference although there are times in which they totally oppose. These differences have to do with the composition of stocks in each index. The way each index is calculated and the weighs allocated to each stock. These differences explain the discrepancies between return rates and the different indexes. Following you’ll find a debate over stock indexes badly used.
