July P/L Challenge: How did I make the most out of volatility?

My real portfolio seem to made a profit loss 📉 as I'd timed ⏲️ the market slightly wrong = did not get the best highest price for tendies...
Well, whatever... I just has to time ⏲️ the lowest next (By the way, for the day... I timed ⏲️ the price within the top few. But for the week, I got trashed 🗑 for timing wrongly = still learning 📖 * Still never learn my lesson yet eh? = Timing the market again ...)

Which stocks did you choose in volatility?
It depends...
Some ppls / investors have 2 seperate portfolios = aggressive vs defensive or short-term vs long-term.
For aggressive portfolio, of course choose stocks that are more volatile like $Tesla(TSLA.US)$, $AMC Entertainment(AMC.US)$, $GameStop(GME.US)$ & many others more...
For defensive portfolio, choose those that are less volatile & are a strong stable company like $Alphabet-A(GOOGL.US)$ (well, not really sure if can say that now for the short-term ), $Coca-Cola(KO.US)$, $McDonald's(MCD.US)$, $Berkshire Hathaway-A(BRK.A.US)$, $SPDR S&P 500 ETF(SPY.US)$, $Vanguard S&P 500 ETF(VOO.US)$, ...

Why did you choose them?
Well, because it's more easy to trade for the short-term & less worries for the long-term as I'm sure/confident that it will do well in the future.
Did you adjust your return expectations?
Yup , I'm a flexible investor. I adjusted my strategies to my comfort & torrent level based on the changes in the economy .
Are you looking for a more diversified and resilient portfolio?
I'm trying to go for a more diversified portfolio as it's safer ?
