Aug. Byebye! Sep. Buybuy! Could September Effect Bring Buy Point?

As of August 28th’s close, $NASDAQ(.IXIC)$ and $S&P 500(.SPX)$ are up 2.76% and 2.56% respectively. The pullback that the market had been waiting for never came, yet the enthusiasm has already cooled down significantly.

What happened in August? How was your portfolio?

August saw weaker profit-making effects as sector rotations dominated and meme stocks made a surprising comeback.

Which stock brings you profits?

The "Mag 7" earnings were mixed, with none severely missing expectations, though $NVIDIA(NVDA)$, despite strong numbers, failed to dazzle.

$UnitedHealth(UNH)$ plunged post-earnings, only to rebound after rumors of Buffett increasing his stake.

Powell’s dovish tone earlier this month boosted sentiment, but Trump’s comments about firing Fed governors quickly reminded markets of political risks.

Despite these twists, the market ended August on solid footing.

What may September effect bring us?

September has historically been the worst month for the S&P 500.

After months of steady gains with little pullback, the market often experiences post-summer rebalancing as traders return from vacation and adjust positions, behavioral biases leading investors to trim positions after rallies, mutual fund fiscal year-ends forcing the sale of underperformers, rising volatility and retail participation, hedging activity for Q4.

September could be tedious but also rewarding if played well, while long-term investors can largely ignore the noise.

    八月份表现平平,没有什么买入。只是趁反弹出掉了一直亏损很久的股票。感觉股市涨得太快了,9月可能会回调一波。
    现在等着英伟达下跌来买入。 @Tiramisu2020

    對我來說,八月更多的是行業輪動,而不是大幅上漲。我的投資組合保持綠色,主要來自防禦性股票和削減一些科技股。英偉達的 $英偉達 Corp(NVDA)$ 強勁的盈利並沒有對市場產生太大影響,這提醒我對預期保持謹慎,不要盲目追逐勢頭。

    對於9月份,我認爲“9月效應”與其說是迷信,不如說是季節性再平衡——基金削減和投資者鎖定利潤。波動性通常會上升,所以我會小心短期交易,但長期頭寸會保持穩定。這是紀律比預測更重要的一個月。

    在下跌時,我會關注特斯拉 $Tesla Motors(TSLA)$和Palantir $Palantir Technologies Inc.(PLTR)$ ,而醫療保健提供穩定性 $Oscar Health, Inc.(OSCR)$ .九月可能會波動,但它通常會在年底前建立有吸引力的切入點,這就是爲什麼我準備好現金。

    The September Effect is a supposed market anormaly whereby the stock market returns are relatively weak during September. The stock market’s solid gains during August 2025 have brought the indexes to new highs. Such high performance will be difficult to duplicate in the September. Although the Fed has hinted rate cuts, it still has to depends on whether labor-market weakness continues to look like a bigger risk than rising inflation. And the new inflation data has showed rising prices is still a risk heading into September. There might be some volatility in September and hopefully it is a great buying opportunity if the market rally into year end. Buy the dip $NVIDIA(NVDA)$🚀🚀🚀 Thank you & “Big Like” to @Tiger_comments @TigerStars @Tiger_SG @Tiger_chat @MillionaireTiger @icycrystal

    My august trading performance has been good so far. I believe in the September effect to a certain extent. I have been eyeing to buy more semiconductor related stocks such as NVIDIA and ASML in case it dipped further below my intrinsic value.

    The ways of trading have changed since the online platforms like Tiger and Moomoo started operating. So the worse months to trade or to buy have changed too. I remembered a few weeks ago, many also said sell in August but look what happened, nothing. August reminds the same... a normal trading month

    八月是一个非常好的月份,香港/中国和美国股市都上涨。回调并没有发生。


    今年九月将与往年不同,因为每个人都希望降息,而降息自上次降息以来进展缓慢。如果美联储给马克预期的结果,市场很有可能因这种乐观情绪而上涨。


    对我来说,九月效应可能只是市场趋势,因为投资者和交易者会审查他们的投资组合并做出相应调整。所以,从这个意义上说,这是科学的,一点也不迷信。市场波动通常与市场事件一致,如财报季、通胀报告以及最近的战争和停火。


    作为交易者和投资者,我们管理风险并相应地进行交易。我认为更重要的是保持坚定、目标清晰和风险管理。


    如果市场下跌,我将考虑添加更多VTI。它是多样化的,从长远来看,世界指数可能会上涨多于下跌。

    My Aug portfolio dropped a little but it is as expected. I will continue to buy few tranches on shares which is also in the list mentioned if they continue to fall. [Cool]

    August stocks fly too high, if September have a healthy pullback, it is a good time for DCA, however we can't time the market.... @AI_Dig

    🌟🌟🌟On August 28, the S&P500 Index closed at a record breaking 6,501, its 28th all time high of 2025.  That was not a fluke. It was a crescendo.  A surge in Tech Titans like Google, Amazon pushed the index higher, defying gravity even as other sectors wobbled.  It marked a 10.5% climb year todate and a stunning 30% rebound from its April low.  This wasn't just a rally.  It was a roar.

    My conviction in $SPDR Portfolio S&P 500 ETF(SPLG)$ is paying off as I am up 47%.  SPLG is the mini version of SPY with a super low expense ratio of 0.02%.  Both ETFs are managed by the same fund manager State Street Global.

    Why did August shine?

    Texh resilience : AI optimism and cloud infrastructure demand ignited faith in US megacaps.

    Easing interest rate expectations.

    And September?

    September may test the nerves of short term traders but for me, it is just another chapter in a long beautifully compounding journey.

    Usually September is a quite month with many stock price down. Just keep extra cash and buy the discounted stock 😆

    August was rather meh for me because I started being rather cautious in preparation for the September effect. September effect isn't a superstition but more of seasonal portfolio rebalancing. I've set aside cash to buy the dips, so let's see 🔥🚀

    The market is influenced by countless variables while relying on the "September Effect" as a precise trading signal is risky though it is not entirely superstition it is not a reliable predictor of future performance either even if September has historically been the worst month for the S&P 500。。。
