Read full description
What is "Kabyuu"? Kabyuu is a stock investment management and analysis app that uniquely aggregates, reorganizes, and graphs past transaction data that is not stored on securities company websites. It supports US stocks, ETFs, and multiple accounts. With diverse visuals and abundant analysis functions, it "visualizes" the past and present of your stock investments. (Some content is paid.) ■Main Features of the App■ ▼Asset Trends Automatically collects and graphs past asset increases and decreases and portfolio changes that are not stored on securities company websites. You can check the performance of asset trends for any period, including the last 10 days, month, year, and all past periods. 【Monthly Report Function】 This is a Kabyuu original content that allows you to see the changes in your monthly investment status at a glance by consolidating individual analysis items from each function and content within Kabyuu, such as profit/loss trends, win rate, and profit-contributing stocks, onto one screen on a "monthly basis." ▼Transaction History Displays past transactions of Japanese stocks, US stocks, and investment trusts in chronological order. Exit history is linked to entry information, allowing you to review each trade as a single transaction. [Golden Arrow Function] *Patented This function connects entry and exit points on the stock price chart with lines, visualizing buy and sell timing. [AI Trade Diagnosis] Kabyuu AI objectively evaluates your trades. It analyzes the quality of entry and exit timing, price movements during the holding period, stock price trends after sale, overall market sentiment, and even disclosed information such as financial results and earnings revisions, providing a deep analysis of your trades from multiple perspectives. ▼Profit and Loss by Stock "Realized Profit/Loss," "Unrealized Profit/Loss," and "Dividends" for each stock are displayed side-by-side, and you can check the "Total Profit/Loss" by summing all of these, allowing you to see your overall performance including dividends. Furthermore, the changes in position and the trends in stock price and profit/loss amount for each stock are displayed in a single graph, allowing you to review "your history with that stock" at a glance. [Analysis of Trading Results] This analyzes your entire past trading history across multiple evaluation axes, including trading type (spot/margin), holding period, market capitalization of the stocks, and holdings across fiscal year-ends. It displays profitable trading trends in a graph. You can also check trading performance for each stock, such as win rate and payoff ratio. ▼Heatmap This shows the daily trends of your holdings from various angles. [Amorphous Heatmap] This represents the total value of your holdings and their rate of return using tile size and color. You can get an overview of your portfolio and intuitively check changes at a glance. By comparing the past and present, you can also check changes in your holdings and fluctuations in their composition. [Asset Composition] This graph shows the proportion of your holdings in Japanese stocks, US stocks, investment trusts, and cash, allowing for intuitive understanding. ▼Portfolio In addition to "profit and loss information" and "fundamentals" for your holdings, you can also check information such as "timely disclosure" and "fiscal year-end/ex-dividend dates," including for stocks you do not hold. [Timely Disclosure] Timely disclosure information released on the day is consolidated on one page for efficient checking. Furthermore, it supports US stock earnings information (with AI translation function), allowing for smooth access to overseas information. [Earnings and Ex-Dividend Date Schedule] You can view a list of scheduled earnings announcement dates for Japanese and US stocks, as well as dividend and stock split ex-dividend dates for Japanese stocks. ▼Watchlist You can register stocks of interest as "watchlist stocks" and track them continuously. This can be used in a wide range of situations, such as pre-investment consideration, post-trading review, tracking, and analysis. ▼Individual Stock Information Page This page provides a clear summary of each stock's "IR information," "supply and demand information/position status," and "fundamentals."
