Theme Guides
Themes are how people actually think about portfolios. Not “will this ticker go up” but “is AI infrastructure still the right place to be”, “does my income side need more dividend growth”, “am I exposed to defense modernization at all”. Each theme below lists every stock that fits, the ETFs commonly used as passive proxies, and how to build a basket around it in Walnut.
