Can someone explain what happened here in after market hours?

I see this huge drop

Can someone explain how this is possible?

 

It is not.

 

Time for you to get a charting s/w that doesn't display after market hours.

If not, you will suffer from Data Analysis Paralysis.

 

Maybe Google is pulling data from a different source or a technical glitch?

Another source, there's some crazy action going on there in the intraday session, that is for sure.

 

How come schwab platform is not showing this huge drop?

 

I don't know. In how many exchanges can you trade NVIDIA? We must be looking at different exchanges.

 

@Drawdown Addict, the 9.22am sell-off is around 2.1% so IMO not too exciting. Also, the sell-off could be Mark Stevens or Jensen Huang selling shares, & as their shares are sold with algos their sell-offs aren't always tradeable (as the algo will stop selling shares if the price becomes too cheap). You can check here in a few days:

Chart displaying regular + extended hours:

 

You should be able to see the sell-off at 9.30am on Wednesday starting around $134, use a 1 minute chart, it's only around 2.1% so it's not huge

 

Schwab is the worst at after market price adjustments. I see those valleys in prices almost every day especially for illiquid securities like some of my credit ETFs & CEFs. Their current price algorithms are really bad.

Even intraday Schwab shows the last traded instead of the bid or ask if there is a huge gap in price. This is really true for illiquid securities.
