NVDA's strength supports market optimism; a close above 240 could turn 235 resistance into support.

I'm particularly keeping an eye on Nvidia, as it continues to rise to new all-time highs. It is the largest stock in the world. It was a tech-driven rally, and suddenly the biggest stock in the tech sector is taking it to new heights.

But right now, if you're looking for a stock that will keep this market close to new highs, it's Nvidia. That's what it's doing.

I see Nvidia knocking on 237's door again now. Apparently it hit an all-time high last week, which helped the Nasdaq.

So I like the market to close at new highs and that's why Nvidia is making me a little optimistic, because if they can close at 240 now, the old resistance around 235, which we are struggling to stay above, could now act as support, let's see how it closes today.

Yes, it could be support and suddenly the narrative will change because the fear of missing out will work, since Nvidia has been stagnant for quite some time.
