I closed 60.0 share(s) $Amazon.com(AMZN)$  ,Amazon hasn't capitalized on the current semiconductor and AI trends. Its main revenue still comes from e-commerce, and its cloud computing business only accounts for about 10-15% of its revenue. Moreover, there aren't many new stories or exciting developments to tell in that area right now.

I closed $ProShares UltraPro Short QQQ(SQQQ)$  ,In reality, this trade is profitable, but Tiger's calculation method shows it as a loss. I’ll continue to close out my short SQQQ positions.

I closed $Tesla Motors(TSLA)$  ,I sold half of my Tesla shares while there's still a profit. Tesla and Nvidia both have a highly speculative nature and significant volatility..

I closed $Advanced Micro Devices(AMD)$  ,AMD is a solid company, and its products have made significant progress. However, its stock has been overhyped recently.

I closed $Tesla Motors(TSLA)$  ,I sold half of my Tesla shares while there's still a profit. Tesla and Nvidia both have a highly speculative nature and significant volatility.

I opened $Alphabet(GOOG)$  ,Google's recent performance has been relatively weak, but that might be exactly the time to buy. Buying a stock when a company is underperforming is a tough decision. Whether to buy at this point depends on your trading style and strategy. You can accumulate a position during its slump or wait until it breaks out in price before buying—both approaches are valid.

I closed $Eli Lilly(LLY)$  ,LLY is an excellent stock, standing out with very stable performance among pharmaceutical stocks. However, it's been growing quite a bit recently, so I'm trimming my position slightly.

I opened $iShares 20+ Year Treasury Bond ETF(TLT)$  ,I used the remaining cash to buy in, because I believe it's a relatively safe and rewarding investment.

I opened $Alphabet(GOOG)$  ,I bought a small amount of Google stock, not for any particular reason, but just to diversify my holdings a bit and avoid being too concentrated in Apple and Microsoft. Additionally, its valuation seems relatively more attractive compared to others.

I closed $PDD Holdings Inc(PDD)$  ,I liquidated my Pinduoduo position. Although I made a small profit this time, I realize that when I bought it, it didn't align with my stock-picking rules, and I shouldn't have done that. It's important to stick to my trading discipline.

I closed 2000.0 share(s) $ProShares UltraPro Short QQQ(SQQQ)$  ,I continued to close out some of my short SQQQ positions. Their purpose was to capture the rebound after the rapid drop earlier. Now that the situation has changed, holding them any longer would go against my original intent.

I closed $NVIDIA Corp(NVDA)$  ,This Nvidia position is still profitable, even though the gains aren't significant. According to Tiger's trading rules, it shows as a loss, but that's okay. I've already reduced a lot of my Nvidia holdings, and this is the last portion.

I closed 2500.0 share(s) $ProShares UltraPro Short QQQ(SQQQ)$  ,I've decided to gradually close out the additional shares I bought during the dip a month ago. This will help me better prepare for the upcoming market conditions.

I closed $American Express(AXP)$  ,American Express, Visa, and MasterCard—I believe choosing just one is sufficient. Currently, no one can challenge their dominance in the credit card industry.

I opened 1 lot(s) $AAPL 20240830 232.5 CALL$  ,I sold a call option at a strike price that's almost impossible to be exercised, accepting some loss in fees. The main goal was to complete the weekly options trading task and earn Tiger's reward points..

I opened $Alphabet(GOOG)$  ,It's indeed challenging to find the right stock and the right buying opportunity. Adding a bit more to my Google position still feels relatively safe.
