Which ai etf is best?

The deep research logic is organized as follows: 

Okay, let's tackle the user's question: "Which AI ETF is best?" The user is interested in the China market, asset management, military, Tencent, and Berkshire Hathaway's portfolio. They focus on technical analysis and short to medium-term investments. 

First, I need to check the provided references. The main data points are about the Spear Alpha ETF (SPRX.O). It's an actively managed ETF with a focus on AI, robotics, and active equity. The historical performance shows a 40.68% 1-year return and 108.85% 3-year return, which is impressive. The expense ratio is 0.75%, and AUM is around $63.97 million. The top holdings include NVIDIA, Marvell, and Vistra Corp. 

Looking at other AI ETFs mentioned, like Fidelity's FTEC.P with $14.53 billion AUM and a low expense ratio of 0.08%, but it's passive. The user might prefer active management for better performance, especially in a niche like AI. 

The user's profile mentions interest in technical analysis, so I should highlight SPRX's recent performance and volatility. The 1-year return is 40.68%, which is strong. The expense ratio is higher than some competitors, but the AUM is growing, indicating investor confidence. 

Also, the user is interested in buy-in prices. The Spear Alpha ETF's last price is $31.85 with a 0.86% change. The 1-year performance is 40.68%, which suggests it's been a good performer. The AUM growth from $55.5M to $63.97M shows increasing interest. 

I should compare SPRX with other AI ETFs but the references don't provide much data on others. The user might appreciate knowing that SPRX is actively managed and focuses on breakthrough innovations, which aligns with their interest in potential high-growth areas. 

The user's focus on technicals means mentioning the Sharpe ratio and volatility would be relevant. However, the references don't have specific data on SPRX's Sharpe ratio, but the historical performance suggests it's a high-volatility, high-reward option. 

In conclusion, SPRX stands out as a top AI ETF due to its strong performance, active management, and focus on key AI companies. It fits the user's interest in high-growth, technically driven investments with a short to medium-term horizon.
