Portfolio Stalker calculates the Market Cap of a company in real-time, using the current stock price and common outstanding shares as reported by the last quarterly results. Companies may change the number of outstanding shares before or after a quarter. This is not reflected until the next quarter.

Companies provide the next earning date in the quarterly reports. However companies frequently update these dates as the date gets closer so the dates may change. Portfolio Stalker takes every effort to update the dates for S&P 500 and NASDAQ 100 companies, however we cannot guarantee the exact dates and they may fluctuate, by as much as a week. Earning dates for stocks outside these indexes are not updated from the last quarterly reports.

Stocks statistics, related to the last quarterly report, take 3 to 4 weeks, after the quarter announcement, to be updated.

Your current daily portfolio values can be seen by opening the History tab. The daily value for each portfolio is calculated after the Close value is set at 8pm.

The option graph shows the volume and open interest for Calls and Puts. Options volumes and open interest can indicate market sentiment, for example where the market projects the stock price will be by the end of the week, next week or next months. Options price quotes are as of the end of the previous trading day.
