The deep research logic is organized as follows: 

Okay, the user is asking how to invest in gold. Let me start by recalling the references provided. The user is an active investor interested in short-term trading, so I need to focus on strategies that align with that approach. 

First, I should outline the main ways to invest in gold. From the references, there are physical gold, ETFs, mining stocks, and futures. Since the user likes technical analysis and market sentiment, ETFs and mining stocks might be more relevant because they're traded on exchanges and can be analyzed with those methods.

Looking at the references, Number 5 and 6 mention physical gold, ETFs, and mining stocks. Number 7 talks about ETFs being recommended by experts, especially in turbulent times. Number 16 lists top gold ETFs with performance data, which is useful. Number 18 also emphasizes ETFs for immediate exposure without physical storage.

The user's interest in short-term trading suggests they might prefer ETFs or mining stocks because they can be traded more flexibly. Physical gold is more of a long-term hold, which might not align with their short-term focus. Also, the user likes stocks with strong buy ratings and potential for short squeezes. Mining stocks (like those in Number 17) could offer that volatility and squeeze potential.

References 20, 21, and 22 discuss portfolio allocation, with some experts recommending 10% in gold. This could be a way to suggest a balanced approach but highlight the short-term strategies within that. Number 28 mentions the VanEck Gold Miners ETF (GDX) rising 34% in 2025, which is a strong performer and fits the user's interest in top-performing stocks.

Risks are important too. References 13, 14, 15, and 36 point out volatility, lack of income, and geopolitical factors. The user should be aware that gold's price can swing, which is both a risk and an opportunity for short-term traders. Also, Number 36 mentions Goldman Sachs doubting gold as an inflation hedge, which adds a layer of caution but also highlights the need for careful analysis.

The user's preference for technical analysis means I should mention how to apply it to gold ETFs or mining stocks. For example, tracking price trends, volume, and key levels. Also, market sentiment indicators like fear/greed indices or geopolitical news affecting gold prices.

In terms of structure, I'll start with a conclusion that gold offers short-term opportunities through ETFs and mining stocks, then break down the strategies. Each strategy should include how it aligns with the user's interests, like liquidity, technical analysis applicability, and potential for volatility.

I need to cite the references properly. For example, when mentioning ETFs, cite Number 16 and 18. For mining stocks, cite Number 17 and 28. Risks should be cited from Numbers 13, 14, 15, and 36. Also
