Mastercard's 1.39B Volume and 38th Rank Signal Bullish RSI Momentum as Stock Retests All-Time High

Mastercard (MA) closed 0.13% lower on August 21, 2025, with a trading volume of $1.39 billion, ranking 38th in market activity. Technical analysis indicates the stock is retesting its all-time high near $595 after rebounding from the 200-day moving average in mid-June. The recent breakout above $570 resistance and RSI momentum above 60 suggest sustained bullish momentum. Historical patterns show similar RSI improvements coincided with prior rally phases in 2023-2025, reinforcing the case for continued upside.

Key support levels at $585.37 and $567.23 could provide short-term stability if the stock faces pullbacks. However, the RSI14 at 76 signals overbought conditions, increasing near-term volatility risks. While the 50-day moving average remains above the 200-day line, a breakdown below $562.03 would trigger sell signals. Analysts note the absence of bearish momentum divergences seen in previous peaks, suggesting this rally could extend further if the $595 threshold holds.

Backtesting of a volume-based trading strategy (top 500 stocks by daily volume, held one day from 2022) showed mixed results: 31.52% cumulative returns over 365 days with a 0.98% average daily gain. The approach delivered best performance in June 2023 (+7.02%) but suffered a -4.20% loss in September 2022, highlighting sensitivity to market volatility. This underscores the strategy’s reliance on short-term momentum rather than fundamental catalysts.
