I have a question which I'm hoping someone can shed some light on. I decided to tally up how many funds I had deposited into Robinhood over the time I have used the app through the completed transfers sections. The number was nearly $5,000 short of the current net worth of my portfolio.

    In terms of 'realized profit' over the lifetime of trading securities on RobinHood, I am $700+ in profit. Can someone help me understand this discrepancy? I have not made any significant withdrawals from this account, so not sure why I am down in actual value. This $5,000 delta is not visible in my portfolio either.

    Why does the math not add up?

    1. If your portfolio value is $5000 more than your total deposits and you have $700 in realized gains with no withdrawals, it means there’s $4300 in unrealized gains. It will not become realized gain until sold (and it would also become a taxable event).

    2. I’ve tried to explain this to a few clients like this; not all of them “got it” so maybe the lecture still needs some cleaning up. See what you think.

      Suppose the starting value of your portfolio is $1000. Later, it’s $1200. What happened?

      Well, you’d think that you could derive it like thusly:

      Starting ± Addns/ ± Invest = Ending
      Value Subs Perform Value

      Problem is, you can’t **know** “Investment Performance”. You can only **derive** InvPerf from the other three values, which you CAN know. Consider:

      * Starting Value $1000, ending value $1200, no deps/withdrawals?
      * Investing Performance must be +$200
      * Starting Value $1000, ending value $1200, $100 deposit?
      * Investing Performance must be +$100
      * Starting Value $1000, ending value $1200, $100 withdrawal?
      * Investing Performance must be +$300
      * Starting Value $1000, ending value $1200, $500 deposits?
      * Investing Performance must be **-$300**.
      * Starting Value $1000, ending value $800, $300 withdrawals?
      * Investing Performance must be **+**$100 (even though ending bal is lower)

      That should help “the math to add up”.
