Some stock is bought to flip within a week. Some is held for months or years because it's expected to rise. The second kind behaves like an investment, so it helps to track it like one.
Value it every day
Flipdesk checks a market value for your stock about once a day, from current listings that closely match each item. A value you type yourself is always kept.
Watch the trend, not just today
Portfolio adds those values up into a chart of what you're holding over 7 days, a month, three months, a year or all time, with your gain on cost and a trend line for each holding.
Sell with confidence
When something has risen well past what you paid and the trend is flattening, that's a good time to list it. When it's still climbing, you can hold with the numbers to back you up.
