We used our publicly available analysis tools to understand the performance of the Nasdaq Composite index within a historical context of market performance. In particular, we wished to better understand how Nasdaq Composite index performance in May 2025 compared to performance in May of previous years.

Historically and on average, the Nasdaq Composite index has shown positive returns in May. Figure 3 shows average monthly (January to December) returns for the Nasdaq Composite index from January 1995 to May 2025.

In May 2025, the Nasdaq Composite index had a gain of 9.56%. As shown in Figure 4, this is the second best May performance ever for this index since May 1971.
We then looked at monthly returns of the Nasdaq Composite index from November 2023 to May 2025 (Figure 5). Figure 5 shows that May 2025 performance is the best performance for any month since November 2023.
