$CrowdStrike(CRWD.US)$ Thanks CRWD, it's been 5 months of profit in just one day

$NVIDIA(NVDA.US)$ what happened? is this a pattern for most Fridays to drop near the end of trading?

$Advanced Micro Devices(AMD.US)$ Bought some at 151, reason: fell near MA200.
$Tesla(TSLA.US)$ Bought some at 237, reason: I added positions around 235 as planned.
I didn't buy much. Buy in batches, then drop and buy again.
They sold some small plates of garbage, and after two days, profits went back up, and some even lost some money. It was really uninteresting. However, I didn't expect this garbage to make any money; I just played around, and the positions were very small. You still have to play the big market to trade stocks. Unless there is another zero-interest rate spill, the chances are minimal.
