Why would a mutual fund plummet on the same day it pays its annual distribution & capital gains? [duplicate]
The price of a share of a mutual fund is its Net Asset Value (nav). Before the payout of dividends and capital gain distribution, the fund was holding both stock shares and cash that resulted from dividends and capital gains. After the payout, a share only holds the stock. Therefore once the cash is paid out the NAV must drop by the same amount as was paid out per share. Thus of course assumes no other activity or valuation changes of the underlying assets. Regular market activity will obscure what the payout does to the NAV.
