Following prices and holdings in one place
Investors who follow several shares tend to end up with prices in one place and holdings in another. MarketMonk tries to join the two. You add the stocks you watch, then build a personal portfolio next to them.
The app tracks stock prices and market performance, so the watchlist and the portfolio sit in the same dashboard.
Line charts and portfolio monitoring
The main analysis tool is the line chart. It lets you explore price movements and gains over time instead of reading a single number.
Portfolio monitoring covers the shares you hold and how they perform. You can also organise the information you care about and change settings to match the way you prefer to view your investments.
