The Nikkei 225 closed at 59,140 (-0.75%) amid a volatile trading session that saw the index oscillate between a low of 58,621 and a high of 60,014. The day's decline reflects a slight pullback after recent gains, highlighting a cautious sentiment among investors as the index approaches its 52-week high of 59,586.

From a technical perspective, the Nikkei remains in a robust position, trading above both the 20-day simple moving average (SMA) of 55,951 and the 50-day SMA of 55,730, indicating a bullish trend. However, the 14-day Relative Strength Index (RSI) at 78.2 signals that the index is entering overbought territory, suggesting that a correction could be on the horizon.

Looking ahead, key levels to watch include the psychological resistance at 60,000 and the support level around 58,500. A sustained move above 60,000 may open the door for further gains, while a breach below 58,500 would warrant closer scrutiny of market momentum.
