$Microsoft(MSFT.US)$ a good time to buy?

$Microsoft(MSFT.US)$ down a sweet $100bn in market cap due to the UBS downgrade. Sees 24.5x FCF as “not cheap given <10% revs growth”
One sentence, $100bn gone in people’s brokerage accounts. That’s finance.

$Apple(AAPL.US)$
$Microsoft(MSFT.US)$
Tech giants have had a tough time lately. In particular, Tesla led the decline, and the stock price collapsed. Apple also fell below key support, forming a typical multi-top structure. The high at the end of last year will probably not be surpassed in the next two or three years. Shorting these stocks, on the other hand, would be a good way to hedge against risk.
However, how do you go short?
1. Shorting individual stocks means first borrowing shares from a brokerage firm and selling them, then buying and returning the shares in the future. This is one of the worst methods: no matter the risk of misjudging the direction and rolling. Let's just say that if you borrow stocks from a brokerage firm, you must not only pay interest, but also have a security deposit. I didn't do anything, and I just lost money, which is very uneconomical.
2. reverse etf. For example, this strange thing called TSLS, $DIREXION DAILY TSLA BEAR 1X SHARES(TSLS.US)$ Or go directly to sqqq, fngd, etc. Whether leveraged or not, these ETFs themselves are not cheap to hold. For example, take a look at the closing price of QQQ yesterday, and find the day before that, the QQQ closing price was the same as yesterday. If you buy QQQ and haven't moved, you won't make a profit or loss. But if you compare the prices of sqqq and tqqq, you'll find that no matter which one you buy, you've lost quite a bit; the longer it takes...
