One year is again behind us (in this case, it was 2025), and we are all a little older (and hopefully richer and/or wiser). Turn-of-the-year period is usually an excellent time for a short recap. Over the past 12 months, we have kept our pace and published nearly 70 short analyses of academic papers and our own research articles. So let’s summarize 10 of them, which were the most popular (based on the Google Analytics ranking). The top 10 is diverse, as usual; once again, we hope that you may find something you have not read yet …

In Understanding Gold, Claude B. Erb and Campbell R. Harvey examine gold’s enduring reputation as a safe-haven asset and contrast popular narratives with empirical evidence. While gold has preserved purchasing power over millennia—what the authors call the “golden constant”—this does not translate into reliable short- or medium-term inflation hedging. Gold’s volatility is comparable to equities, while inflation itself is far more stable, making gold an unreliable hedge over typical investor horizons. The key insight is that gold’s real long-run return is approximately zero, which is precisely what one should expect from a hedging asset rather than a growth asset.

In recent times, we have observed heightened volatility across financial markets. Concerns surrounding government shutdowns, as well as the uncertainty they create, do little to calm these fluctuations. Rather than being purely disruptive, however, such events raise an intriguing question: could these episodes of political and economic uncertainty actually be leveraged to our advantage in investment strategies? In this article, we will examine several asset classes and attempt to assess whether this phenomenon provides a sufficiently relevant signal for investment decisions.

Investors are increasingly exploring alternative indicators to gain an edge in financial markets. Traditional signals, such as earnings reports or macroeconomic data, often come with delays or may already be priced in. As a result, unconventional metrics have attracted attention. In this article, we examine the Producer Price Index (PPI) for the Corrugated and Solid Fiber Box Manufacturing industry, including corrugated boxes and pallets. Our motivation is to evaluate this index’s effectiveness as a predictive signal for the S&P 500 ETF, sector-specific ETFs, and individual stocks such as Amazon (AMZN), one of the largest consumers of materials tracked by this index. We present several investment strategies that incorporate this indicator and assess whether it can enhance risk-adjusted returns.

Bitcoin is one of the most widely discussed financial assets of the modern era. Since its inception, it has evolved from a niche digital experiment into a globally recognized investment instrument with institutional adoption and billions in daily trading volume. Despite its inherent volatility, Bitcoin has demonstrated a strong long-term growth trajectory, making it an attractive candidate for trend-based and momentum-oriented trading strategies. In this study, we apply concepts from technical analysis to construct and refine a trend-following strategy for Bitcoin, progressing step by step from a simple MACD setup toward an improved multi-timeframe model.

The clustering of excess returns on the final trading days of the month constitutes a robust empirical regularity with significant implications for portfolio construction. We document a month-end premium that is both statistically and economically significant, distinct from the canonical turn-of-the-month (ToM) effect. Our strategy highlights systematic style rotations—particularly shifts in value versus growth exposures, as proxied by the IVE–IVW spread—and documents parallel contemporaneous dislocations between real-estate and broad-equity benchmarks, as measured by the IYR–SPY spread.
