Stock-tracking app

Hi, all.

Does anyone know of an app or a website that will notify you when a stock goes up or down by a certain percentage?

no because I don't buy individual stocks. I own the market. why are you owning individual stocks? Do you think you know more than the market? If 80% of mutual fund managers don't beat the market every year, what makes you think you will?

have you read (and understood) this:

Guy asked for an app, not to be scolded for your beliefs.

I use my Fidelity app as it allows me to set notifications on stock prices. I go into the watch list then click +Alert. Does exactly what your asking for.
Most finance sites like Yahoo Finance will allow you to setup watch lists and in turn email notifications.

The Schwab and TD Ameritrade sites and apps will send notifications as well.
You could also set up limit orders to buy on certain prices automatically.
What platform are you using to buy stocks?

My apologies for that mistake.

A related question: how does one know how much he or she is paying for a unit of VTSAX? When I ask to buy more VTSAX, I'm prompted to enter a dollar amount, but not given any information on the number of units that particular amount buys.

you get the number of shares based on the amount of money you invest divided by the NAV which isn't determined until the market closes (but you'd have to make a purchase prior to 4 p.m. to get that day's ending NAV).

Google is showing VTSAX price $84.42 (I honestly don't know if that's the price as of open today (Friday's close NAV) or today's close NAV. But let's say it's the close of today and you invested $200 in vtsax before 4 p.m. today.

you'd get 2.369 shares ($200 / $84.42).

if you buy the ETF you have to have the actual money required to buy a certain amount of shares (unless able to buy fractional ETF shares). So if you wanted to invest $200 in VTI, you couldn't. You'd have to buy (assuming shares of VTI right now are $168.58/share) :

1 share totaling $168.58 or
2 shares totaling $337.16

Thank you.

The scenario you suggest is odd: in order to lock in an end-of-day NAV price, I would need to purchase the units before 4 p.m. But that NAV price isn't actually determined until after 4 p.m.; for example, the current NAV price ($84.42) is from last Friday.

Vanguard should be clearer about just how many units one is buying.

ETFs are more straightforward with pricing and real time data. Use VTI instead of VTSAX.

Thank you. The NAV I'm seeing ($84.42) is from last Friday; I suppose it takes a little while after closing time to update. It's peculiar, though, that Vanguard doesn't actually tell you the number of units you're buying.
you can't know because you're buying before 4 p.m. in order to get that day's close. But the day's closing NAV isn't known at 4 oclock as you see. It's only known later after everything settles out.

If you buy now (after 4 pm.) on 9/8/2020 you're not going to get the NAV that settles in a couple hours for today. You'll be buying at whatever the price of the NAV is as of 4 p.m. TOMORROW 9/9/2020 (after tomorrow's close).

so there's no way to know (with a fund) how many shares you're buying.

you can know that with an ETF, which is why some prefer that.

I don't think it matters per se, when you are buying shares over your lifetime.

Does a difference in share price today vs tomorrow going to have an enormous impact overall? No.

Cool story. Next time you have nothing helpful to contribute, feel free to scroll along. We can all do without your snarky remarks.

To the OP:

I’m not sure what OS you’re using, but if you’re looking for an iOS app, head to the App Store and search for “stock alerts”. The search should return a ton of useful apps which provide exactly what you’re looking for.
i think those links were extraordinarily helpful.

there seem to be a lot of new people asking about individual stocks, so I'd assume they haven't read the links I've provided. William Sharpe is a very smart and experienced man and a nobel laureate to boot. Not sure why you'd think he doesn't have anything to offer in the two links I provided above.

The way i look at it is none of your comments answer the question or are relevant to the topic. Bogleheads (and this board specifically "Personal Investments") is about all types of investments. Not just what you deem investments.

That is certainly a feature that your trading platform app could/should provide.

For MF|ETF|Stock I could also do a quick calculation and set up my Buy at the limit.

There are investors who "buy the dip" and that is probably a good description of your question.

Retail traders make up nearly 25% of the stock market following COVID-driven volatility, Citadel Securities says.

The group made up just 10% of the market in 2019. The proportion steadily climbed as brokers slashed commission fees and the pandemic fueled violent price swings.
