August 2025 Markets Review

S&P 500: +4.05%
NASDAQ: +6.14%

September is typically one of the weakest months of the year, and I highlighted my concerns in my previous portfolio review:

Despite these concerns, September has largely been an “up-only” market for the indexes. The S&P 500 posted its fifth consecutive monthly gain while both the S&P 500 and NASDAQ reached all-time highs again.

Chinese equities continued to see strong inflows and performance, with Alibaba leading the charge (+25% in the past month). Gold also saw one of the strongest months on record with a +10% gain into all-time highs.

Markets are clearly in a risk-on environment, like we’ve not seen since late 2021. We know what happened in the subsequent year, though that is merely an observation.

These trends do not worry me at all, as it is typical for markets to go up. However, there are certainly some concerns for me in specific sectors of the market, with many pre-revenue or meme stocks going up exponentially in the past few months.

The quantum sector in particular has been extremely hot, with several of these stocks up over 300% YTD and 100% in the past month alone (RGTI, QBTS, IONQ etc…). I would not touch any of these with a 10-foot pole.

More on my positioning later in this update.
