According to Diamond Hill's 15-minute chart, the Relative Strength Index (RSI) has reached overbought levels, and the KDJ indicator has formed a death cross on August 22, 2025, at 13:00. This suggests that the stock price has risen too quickly and exceeds the fundamental support, indicating a shift in momentum towards a downward trend with potential for further declines.

The RSI indicator, which measures the speed and change of price movements, has reached an overbought level of 70, indicating that the stock has experienced a significant increase in price. This rapid rise may be unsustainable and could lead to a correction in the stock's price. The KDJ indicator, a combination of the K and D lines crossing below the J line, suggests a bearish trend. This death cross, along with the narrowing of Bollinger Bands, indicates that the magnitude of stock price fluctuations is decreasing, and the momentum is shifting towards the downside [1].

The market volatility experienced by Diamond Hill is influenced by various factors, including tariff announcements and market conditions. The benchmark three-month copper contract on the London Metal Exchange (LME) fell by 0.6% to $9,736 per metric ton on July 18, 2025, touching its weakest point since July 18 at $9,720.50 [1]. The U.S.-listed shares of global mining giants Rio Tinto (RIO) and BHP Group (BHP) also experienced declines, falling by 2.3% and 1.8%, respectively. Southern Copper (SCCO) and Freeport-McMoRan (FCX) saw their stocks decrease by 1.9% and ~1%, respectively. Canadian miners Ero Copper (ERO) and Hudbay Minerals (HBM) saw their stocks decrease by ~1% and 1.3%, respectively [1].

Investors should closely monitor Diamond Hill's stock and be prepared for further volatility as the market awaits developments regarding potential tariffs. The technical indicators suggest a bearish trend, with a potential for further decline in the stock's value. While the KDJ Golden Cross and Death Cross signals suggest a potential for further price movements, investors should remain vigilant and monitor the market closely for any new developments that could impact Diamond Hill's stock performance.
