I'm surprised this didn't get a little lower through support, but again it doesn't have to. It might be Nvidia is too bullish to let the dow pull it that low below it's own support. Apple's dramatic sell off this week pulled it well below it's own support yesterday. Nvidia is back above $117 support and we're still waiting on Apple to get back above $216.
Amazon and Microsoft are both floating well above their supports of $164 and $278 respectively, but it's very unlikely they'll ever get there.
Walmart and JP Morgan both hit their supports almost exactly yesterday and have since bounced nicely.
It's interesting last week I learned of two much older people I know who sold off their entire retirement accounts. It's sad, but that's a sign of throwing the towel in at the bottom, rather than timing the top perfectly.
