BUFFALO Funds, an actively managed mutual fund advised by Kornitzer Capital Management, released its third-quarter 2026 investor letter for "Buffalo Growth Fund". The letter can be downloaded here. The Buffalo Growth Fund advanced 4.57% in Q3, significantly outperforming the Russell 3000® Growth Index's 0.45%. The primary driver of this outperformance was stock selection in Information Technology, particularly among hyperscaler stocks that benefited from higher cloud revenue. However, rising oil prices and inflation challenged the market, prompting the Federal Reserve to raise interest rates for the first time since July 2023 and prompting caution within the Fund. The fund has reduced some positions, noting the cost of capital's impact on business models. There is optimism for hyperscalers following the upcoming Anthropic IPO, which could provide investor transparency for future capex.

Buffalo Growth Fund stated the following regarding Sandisk Corporation (NASDAQ:SNDK) in its Q3 2026 investor letter:
"In the previous quarter we determined the portfolio was lacking exposure to the memory ***** e and initiated small positions in both Micron and Sandisk Corporation (NASDAQ:SNDK). Unfortunately, the timing on Sandisk was poor as the stock advanced rapidly through the end of June and then experienced the bottom drop out with nasty momentum unwind in July. We decided to take losses on Sandisk and move on from a ***** e that has historically been incredibly cyclical. Typically, cyclical businesses like this aren't where we focus our time and this experience reminded us of that."
