Quote from Pekelo:
I understand that, but there will be always a little or not so little difference between the EOD quote and the money put to work or withdrawn.
Now I can see that if their traders are good and time the transaction correctly they can make a little extra money on it (buying early with freshly deposited money on a rally day or selling early with withdrawn money on a selloff day) and that extra money could be used for the expenses of the fund instead of for profit...
To avoid a big difference because it can be negative for them:
1. They can execute the transaction as close to market close as it is practical.
2. Average in during the day, this way they gonna at least half the difference.
But again, they might just execute it anytime because with the constant in and outflow, sometimes they win sometimes they lose but it is a breakeven in the long run, although I think they should still try to time it...
I don't think you're getting it right. It works something like this:
1) Fund starts the day with the portfolio that was there at the end of yesterday, say $90M stocks + $5M cash. Say there were 10M shares outstanding yesterday, each share is worth $9.50.
2) Investors send more cash during the day to buy into the fund, say $1M. This stays on the sidelines during the day.
3) At the end of the day the fund calculates its value ignoring the new $1M cash, say $95M stocks (big up day)+ $5M cash, $100M total. Old investors will get the $5M gain.
4) They figure out a new share price for all purchases or redemptions. This is value/old shares, or $10. Old shares were 9.50 yesterday and there are 10M, this is how they get the gains for the day.
5) New shares are issued to the new investors that sent money during the day. $1M came in, shares are $10, so they sell 1000 new shares to the new investors. Now the fund has is worth $101M ($95M stocks, $6M cash) and has 10.001 M shares outstanding.
6) This repeats on normal days. Then on a special day the fund takes out its fees/expenses for the period. Number of shares don't change, but the value goes down by the amount taken out.
A bit simplified but those are the basics.
They might monitor the flows during the day and pre-adjust with the cash they have (from the day before) but they can't get to the new cash until they sell the new shares at the end of the day. If they do what you said and buy early on rally day, this gain goes to the old investors and not fund management.
