DigiFundManager: Investment Software

Sets the conditions under which your past performance is your best predictor of expected portfolio performance.

  • Each week, it screens & ranks stocks from any stock list by decreasing likelihood to increase/decrease in price finding the best long/short positions by taking the highest/lowest ranks (Statistical Arbitrage).
  • It weights stocks to maximize returns and/or minimize risks (Economic Forecasting).
  • It times portfolios by searching for peaks in the autocorrelations of Wall Street's random price fluctuations over several recessions (Wiener-Khinchin-Einstein theorem), which also holds for non-stationary fluctuations such as the ones of Wall Street: (Non-stationary fluctuations). 
Portfolio managers use these techniques to compute optimal portfolios that outperform the market. Perfect Competition sets a cap on each investment from $500 to $250 Million.

Fractional shares can level the playing field between large and retail investments when computed stock weights lead to fractional shares.

Safe investing

Watch the slide show to the right to learn how to minimize your risks and maximize your annual expected returns using DigiFundManager

Expected risks and rewards are averages of the past. Averages have spreads, so that they never warrant future performance. Spreads are indicators for risks.

  • 1. The broker account

    To trade equity, you need to open an investment account with a broker or bank and deposit money that you want to invest. This financial company should enable you to process your buy and sell orders of shares of stocks on Wall Street. It should also enable you to process Market on Close (MOC) orders, hence to trade shares at end-of-day prices, which can be back tested.

  • 2. Buying/selling of own and borrowed shares

    When you buy shares of the stocks of a company, you do that with the expectation that they will increase in value. You hold them for a certain time to let them grow and then sell them. You may also borrow shares of stocks from your broker and sell them with the expectation that they will decrease in value. You hold those for a certain time to let them decrease in price and then buy them back.
  • 3. Watch lists

    Fund Managers select their portfolios from a watchlist. There are about 7000 non-Over-The-Counter (OTC) stocks on Wall Street, which regularly report their financials to the Securities & Exchange Commission (SEC). Our screening conditions can screen any smaller watchlist from this General WatchList. Like only stocks from the tech sector or utility sector, or any of the major Indices.
