I continue to come across this odd fact about mutual fund investing, but I never understood how it works. Let's say I decided to invest in ABC fund the day before year-end distributions. At the beginning of the year, NAV was $10 per share. Then, a year later, NAV increased to $100 per share. At that point, I invest $100,000 at $100 per share. So, now I own 1000 shares of ABC fund. When distributions are calculated, I discover that the NAV or none of the underlying prices have changed since the day prior such that if I had invested in these shares individually, there would have been no gain/loss. Nevertheless, I receive the distributions (and pay taxes on) the gain earned in the fund throughout the entire year, which is 900%. Assuming for the sake illustration that the fund turns over entire holdings, how exactly would this work and what would be my capital gains at this point?

    Your question is really confusing. You bought 1,000 shares for $100 per share ($100k) at the end of the year and you received distributions throughout the year. Also, I have no clue what the 90% refers to. It would be much clearer if you stated that you bought X shares for Y dollars per share on DATE along with the amount of the dividend received on DATE (dividends reinvested on DATE for Z dollars per share, or not reinvested) and then at a later DATE you owned XX shares at YY price. If you do that, proper calculations can be made. Commented Aug 15, 2020 at 17:26
  • A mutual fund doesn't likely turn-over the entire fund holdings in one year and therefor the capital-gains distribution is likely much smaller than a gain in fund NAV.

  • Thanks for the clarification. I meant 900% not 90%, which represents the gain in the fund from 10$ NAV to 100$. I'm using these numbers to highlight an extreme yet conceivable scenario in which I invest in a fund on the day before distributions, and although I've only been invested one day, I receive distributions on the 900% gain that the fund experienced over the entire year. Lets also assume to make it simple that the fund turns over entire holdings and each position was held long term. How is that 900% gain distributed to me? Or how does this work in general?

  • hello! what does "turns over entire holdings" mean ?

  • Referring to S Spring's comment which I assume what is means by that is the fund sold (or traded?) all the shares that it started to the year with.

The premises of the OP's question have several misconceptions that make the conclusions drawn by the OP incorrect. Let us take the basic numbers, unbelievable though they are, as correct: at the beginning of the year, the mutual fund shares had an NAV of $10/share and on the day before the fund declares a distribution, the NAV was $100/share. Typically, much of the increase in NAV is due to increases in the market price of the mutual fund's holdings, and a relatively small amount is due to the mutual fund's activities. That is, it would be an unbelievably rare case that the mutual fund would pay a distribution of $90 per share the next day.

As the OP correctly states, the mutual fund bought and sold the stocks/bonds in its holdings throughout the year, so the fund had capital gains or losses from these activities. The fund also collected dividends paid by the stocks that it held and/or interest paid by the bonds that it held. These items are paid out as distributions to the share holders, categorized as net long term gains, net short-term gains, and dividends, categorized these days into qualified dividends (dividends from stocks) and non-qualified dividends (interest from bonds). For example, in December 2019, Vanguard Explorer Fund had a NAV of a little over $100 per share, but declared a dividend of only $0.2949 per share and long-term capital gains of $4.8967 per share. Net losses are retained by the fund to offset future capital gains (cf. this answer or this one). It doesn't matter whether the mutual fund turned over its entire portfolio once or twice or twenty times or not at all; the distribution amount is determined by the realized gains and losses by the mutual fund's activities, and not by the unrealized gains due to market movement of the prices of the underlying investments. In short, the OP's dreams of getting a $90 per share distribution because the NAV increased from $10/share to $100/share are likely to remain a pipe dream.

As aganju points out in another answer, it is a bad idea to buy a mutual fund just before it declares a distribution (in a taxable account). This is called "buying a dividend" because the distribution is a taxable event (the OP will owe taxes on the amounts distributed regardless of whether the OP receives the distribution in cash or chooses to re-invest it in the same fund (or a different fund). If the OP receives a $5 per share distribution in cash ($5K total), the mutual fund's NAV will drop to $95, and those 1000 shares will be worth only $95,000; that is, the distribution will have no effect on how much money the OP has. If the $5000 distribution is re-invested into the same mutual fund, the OP will now own 1000+5000/95 = 1052.63157... shares priced at $95/share for a total value of $100,000. In either case, the OP has incurred $5000 in taxable income. If the OP had kept her purse shut for just one more day, she could have bought 1052.63157 shares of the fund with her $100,000 after the distribution was declared and no taxable income of $5000 would have resulted. That's why buying shares just before a distribution is declared is not a very good idea. Most mutual fund companies that make distributions in December post estimates of the per-share distributions on their websites by late October or November, and usually have recommendations suggesting that investors not invest in the funds in the days leading up to the day when the fund declares a dividend.

What about the other scenario envisioned by the OP in comments below this answer:

The share price stayed at $10/share all through the year but the mutual fund sold and bought many securities through the year and is now holding a huge amount of capital gains. Can I get some part of these gains by investing $100K (thus getting 10,000 shares) the day before the announced distribution?

Once again, the premises are faulty. First, the NAV of the mutual fund's shares is determined each evening by adding up the total value of all the securities held (using that day's market closing prices of the securities) plus all cash on hand. Almost all mutual funds have a "bank account" (sort of like a petty cash account) into which all new investment money is deposited until the fund manager decides what securities to buy with that new money, and from which all redemptions of shares are paid out, and from which the daily expense fee is paid out to the fund management etc.). So, if the mutual fund has a "ton of gains", that ton of money is either sitting in the "bank account" (very unlikely) or (more likely) invested in more securities until distribution day rolls around. Either way, the NAV would be more than $10/share, and would fall by exactly the distribution per share paid out when the distribution is declared (assuming no change in the price of the underlying securities from the previous day). So, yes, assuming the NAV is $10 in the day before the distribution, the OP can buy 10,000 shares for her $100K, but if the next day, the mutual fund declares a distribution of $2 per share, its NAV will be $8, and while she will getting a check for $20K soon (taxable income!), her 10,000 shares will be worth only $80K. Practically, what will happen is that the mutual fund will just send back $20K from the $100K cash she invested the previous day and so is still sitting in the "bank account" most likely, and will record her as the owner of 10,000 shares she bought (purchase price $10/share). If she tries to redeem those shares the next day, they will be worth $80K only, and that's how much money she would get as the proceeds of the redemption. In short, this is not a quick way to make a buck, but instead a quick way of unnecessarily creating taxable income on which tax will be due soon without any change in wealth.

  • This is super helpful, but I'm not actually expecting this to happen (in real life or in my dreams). I'm simply trying to understand the mechanics of how it works that one could receive a full year's worth of capital gains by being invested for one day. That's why I wanted to use extreme numbers -- so I can follow the implications of this fact to an absurd consequence.

  • Your post actually brings up a lot more questions. An increase in NAV from $10 to $100 in the course of a year does not translate into a $90 per share distribution at the end of the year, and that my distribution depends on the realized gains from MFs activities -- I get that. But then let's say the NAV didn't change at all over the year, it remained at $10/share, but the MF had sold a ton of shares at huge gains -- could I have invested my $100,000 at $10/share in this MF day before distributions and receive all the gains over the year? To simplify, assume no dividends. Is this possible? How?

  • clarification: the NAV coincidentally went back to $10/share at the end of the year (not that it never changed).

  • @Karen See revised answer. Your question is at the end of what I previously wrote. Commented Aug 17, 2020 at 20:46

Buying a fund or an ETF directly before the dividend payment date has the same effect as buying an individual share right before its dividend payment - you get a dividend that is taxable for that calendar year, and the investment price drops by the dividend amount.

Both are similarly bad ideas - unless you love paying taxes, or you are in a special situation (for example, you have larger losses from other investments that you couldn’t deduct), it is typically a poor decision.

Simply watch out for the dividend pay day when you buy significant amounts of shares, funds, or whatever.

Note that if you hold the investment sixty days after the dividend (or bought it sixty days before), the dividend will count as long-term gains.

  • Nits: assuming US, 'qualified' dividends are taxed at the same reduced rates as long-term cap gains, but are reported and computed separately, not netted against losses as cap gains are. In addition to holding for 60 days, and not hedging, it must be from a company in the US or certain other countries, and for a fund/ETF which has multiple holdings the dividend may be only partly qualified (your 1099 will say).
