Odd Market Yesterday?

[marko]

Anyone else see this?
Yesterday, 11/27, the Dow closed down -138, S&P down -22, Nadaq down -115.

Yet despite that every one of my stocks and funds were UP several hundred bucks except for the S&P index fund. They usually follow the market fairly consistently. A down Dow usually brings a down day etc.

Very odd, isn't it? Yes, I know many of you don't track things day to day but even if you don't, don't you find this strange? I have all standard investments, nothing exotic.

Interesting!!! I never checked my numbers today so don't know if up or down. I follow the DJIA as well for what is happening to my portfolio. I do know on days when it is up I may not go up that day but will the next.
It really depends on where those shares are at in the funds you have.

Update> I just checked one account of mine, and it did go down.

Dell was down 12.2%, HP was down 11.4%, NVDA was down 1.2%, MSFT was down 1.2%, AMZN was down 1%. When the largest stocks in a capitalization weighted index fall, the index can fall even if most of the components rise.

Here is an informative table to show what I mean (with respect to the S&P 500)

If you checked in the hour or two after the market closed, the funds may have been showing the closing price (and relative change) from Tuesday (which was up) instead of Wednesday (which was down). But you probably knew that, so... .

Interesting. My “later portfolio “ which has different management strategies in it, was up for the day yesterday.

Could be a sign index stocks are overvalued so money is starting to slosh to other areas.

 

[OldShooter]

IMO there's probably no reason. Short term stock prices are roughly random, so what you have is basically how the dice landed. Meaningless.

I monitor my investment changes in percentages, not share-price dollars.
Nonetheless, all of my domestic stock ETFs were down yesterday, with the exception of Vanguard REIT...

My equity index funds were down yesterday.

This post had me curious to look. I just added everything up, and I'm down about 0.261% compared to 11/26. So while down, that probably qualifies as "meaningless noise" in the overall scheme of things.

Thanks for posting, that is a very helpful table. Remarkable that AAPL, NVDA and MSFT make up 21.8% of the index and the top just 29 equities make up over 50% of the S&P500.

Well known as the S&P500 is a market cap weighted index. Usually 10-12 companies dominate. But they change out over long periods of time - when comparing decades you see big changes in the top 10. Someone linked a timelapse video a while back.

Here it is: NVDA wasn't even in the top 10 in 2020. In fact just compare today 2024 to 2020 and there are big differences. Also worth noticing how different industries have dominated the S&P 500 at different periods of time.

^^^^^

Very interesting. Thanks for sharing. Puts things in perspective.

Yesterday I had 5 funds post gains, 4 funds post losses, with an overall loss of 0.18% for the day because the majority of my funds are in a total stock market index fund.

Very interesting. I worked for the tech company that was in the top during the 80s, by the time I retired (last year), it was gone way down.

I often wonder if the brokerage houses like etrade, fidelity, vanguard etc have some lag time to update composite account values for customers compared to instantaneous values you might see directly.

It never concerned me enough to go do some googlin' though.

I've commented before that Quicken can download and update my Vanguard MFs about 8 minutes after market close, but Vanguard on their own website usually takes about an hour and a half. I don't know why.

I checked the dollars again on the next day. I did compare them to the day before because sometimes there is a lag. I cross referenced between M*, Google sheets, and my own broker. They were all the same.
Not going to lose any sleep over it but just found it a little interesting.

Dividends?

It just depends on so much, including how you’ve diversified. I wish my whole portfolio was up this year as much as the S&P500, but I also like that when some things go down, others go up, keeping me in balance and in some safety.

 

[jollystomper]

The Russell 2000 was up Wednesday. Small/midcap value funds were probably up. I do have one like that (ACMVX) that was up Wednesday.

 

[calmloki]

Got up this morning and opened Morningstar to find that our dip on Wednesday had kicked into a major dive! Realized that most of the dive was due to NVDA having a 100% loss and now being valued at $0. Ten minutes later and all's right with the world, NVDA has a reported value, and I'll get my tryptophan levels back up soon.

 

[GrayHare]

At $0 I'd have bought more, lots more.
