$Intel (INTC.US)$ How do you say, can I join now?

Just saying hi.
There hasn't been much activity recently, still the following four. Except xlv being a drag on eli lilly and co's performance, the rest are quite explosive. However, it's probably close to the end of this surge to 6000 points. After all, Trump has not taken office yet, maybe a bit overpriced.

Today, Dragon and TSM both broke through important resistance levels. I was originally planning to increase my position, but before placing the order, I noticed a problem:
The volume is insufficient.
I hesitated for a moment and did not place the order.
If it had been a breakout with high volume, I would definitely have chased after it. However, for a breakout with low volume, I have some doubts.
As a precaution, I instead reduced my holdings of NVDA.
Let's see how PLTR's financial report turns out. Today's surge with high volume is unlikely to be caused by retail investors; it must be institutions aggressively buying, with retail investors at most following the trend. If there is a stock price plunge after-market due to the financial report, that would be a bit amusing. I'll consider whether to buy put options to protect my profits.

$Tesla (TSLA.US)$
$Vertiv Holdings (VRT.US)$
after earnings, both increase 10+%
interestingly, TSLA has been downtrend and VRT has been ongoing uptrend.
So the question is: do you think it is easier to go up for uptrend stock, or downtrend stock?
What is your thought? is this buyable over the gap up?
