$Advanced Micro Devices (AMD.US)$ why suddenly drop so much this few days?

It's 60%of my portfolio and I have an average up to 6.57 per share after adding more at 20
So, fortunate enough to not technically be in the red. But my over all portfolio has decreased by over 300k since October so it's a little discouraging, but I'm holding for at least a few years, so I'm not really worried about the long term. $NIO Inc (NIO.US)$

There are a few ground rules which I follow when it comes to trading.
First and foremost, I follow a system for everything. For my value investing, I do a certain amount of due diligence before starting a position in any stock. I look through articles, financial reports etc. before I decide if it is worth a buy. Similarly, for day-trading or momentum trading, I go in and go out of a trade solely based on technical indicators. When a system is followed, trades are consistent, and you know exactly what you're doing. You aren't just copying someone off Youtube. You aren't just buying because everyone is talking about it.
Second of all, I fight the urge every time I panic. Emotions are your biggest enemy in the stock market. Sometimes, when you followed your system but things go south, it may be tempting to panic-sell. When we're in this state, it's tough to make rational decisions. It is true that in some situations, for example, if a company is suddenly in a lot of trouble and its prospects are drastically affected, it may be a good idea to cut your losses. However, if your stocks are tanking because major indexes are falling, or because of FUD that's not directly related to the prospect of the company itself, then do think again. Distract yourself. Close the app. If you truly believe in the stock, you wouldn't be panicking. Warren Buffett has never tried to time the market. He is systematic and he does not let his emotions cloud his judgment. This is how it should be done.
Lastly, manage your risk well. Money management is important. I allocate a fixed percentage of my money to blue chips and ETFs. $Apple (AAPL.US)$ , $Berkshire Hathaway-B (BRK.B.US)$ and $SPDR S&P 500 ETF (SPY.US)$ are some examples. This is my retirement money. I also allocate a smaller percentage to riskier ventures like day-trading and momentum-trading. Finally, I allocate some percentage to stocks which have considerable risk associated with them, yet I am going to gamble on the long term prospects because I love what I see right now for these companies. These are mainly Chinese EVs like $NIO Inc (NIO.US)$ , fintechs like $Futu Holdings Ltd (FUTU.US)$ and $SoFi Technologies (SOFI.US)$ , to name a few.
Do not be the one guy who puts 90% of his savings into day trading, only to lose half of it in a week. Manage your risk and your money well. While you're at it, know how to put a stop loss or a trailing stop on your positions if necessary. This is especially important for day trading.

$NIO Inc (NIO.US)$ this stock is stubborn like hell. stucked.

$Luminar Technologies (LAZR.US)$ I bought shares, and it went down.
If you want to make money, do the opposite of what I do.
