It'll mostly come back when the dividend is reinvested by most folks on monday or tuesday.
Hmm, in their divine wisdom, fidelity appears to have prevented direct linking to articles on their fund news, so here it is, likely in violation of some copyright law. They may sue me.
"On Monday, May 7, the Fidelity Magellan fund will pay a distribution to shareholders of $5.28. On Friday, May 4, the fund's ex-dividend date, shareholders of record will notice that the distribution was deducted from the fund's net asset value (NAV) and the NAV at the close of the market Friday was substantially different from the NAV on the preceding day. This is normal.
The Fund's NAV closed at $97.14 on Thursday May 3. As of 4:00 pm on May 4, Fidelity Magellan Fund's NAV will reflect a drop of $5.28 (or 5.5% of the NAV).
On Monday, May 7, the fund will pay a distribution to shareholders of $0.10 per share in dividends and $5.18 per share in long-term capital gains, for a total of $5.28. It's important to keep in mind, however, that distributions do not affect total return. Although the NAV of the fund drops when a distribution is declared, shareholders will either have their proceeds reinvested in additional shares of the fund or they will receive the value of the distribution in cash according to standing instructions they have previously communicated to Fidelity.
Shareholders are required to pay taxes on mutual fund distributions – unless the mutual funds are held in tax-advantaged accounts such as Individual Retirement Accounts (IRAs) and group retirement accounts such as 401(k) and 403(b) accounts – whether the distributions are paid out in cash or reinvested in additional shares.
The vast majority of the assets in Magellan Fund are held in tax-advantaged retirement accounts. Shareholders who own the funds in these types of accounts pay taxes, if any, on fund distributions only when money is withdrawn from the account – in most cases, well into the future.
