Portfolio Value Explained


“All Time” refers to the price movement of the shares currently held in your portfolio, since you bought those shares - it’s a weighted average, taking into account the different prices you bought different amounts of different shares at.

“7 Day” refers to the price change of shares you currently hold that have been in your portfolio for at least 7 days, compared to the weighted average value of each of those holdings, seven days ago. Shares bought less than seven days ago aren’t counted, because they weren’t held at the point in time we compare against.

“24 Hour” refers to the price change of shares you currently hold that have been in your portfolio for at least 24 hours, compared to the weighted average value of each of those holdings, 24 hours ago. Shares bought less than 24hrs ago aren’t counted, because they weren’t held at the point in time we compare against.

The values of these can be different.

For example: If you bought one share and it increased in value 5% on the day you bought it, the all time profit would immediately be 5%, but the 7 day and 24h profit would be zero. If it increased in value by another 5% after the share was held for 24h, it would be 10% all time, 0% 7 Day, and at the time of the price increase, the 24h value would become 5%. If the price remained static after that, the 24h change would return to 0% after 24 hours.

With cash values: If you bought one £10 share and it increased in value £1 on the day you bought it, the all time profit would immediately be £1, but the 7 day and 24h profit would be zero. If it increased in value by another £1 after the share was held for 24h, it would be £2 all time, £0 7 Day, and at the time of the price increase, the £ value would become £1. If the price remained static after that, the 24h change would return to £0 after 24 hours, if the price moved in the previous 24h period, or during the day, this value could vary.

These are simplified examples, and complexity is added when there are different amounts of shares bought and sold at different times, some of which may or may not be counted in the 7 day and/or 24h calculation depending on when they were bought, and the fluctuation of multiple share prices in both the retrospective 7 day and 24h retrospective windows, and the various points in time at which a user checks their portfolio stats.
