- A core-satellite portfolio splits investments into stable core holdings and higher-risk satellite picks.
- The core is usually 60% of the portfolio, with satellites at 40%.
- It blends passive index investing with active opportunity bets.


Copyright law was built to stop people from copying songs. It was not built to stop a free AI tool from making a brand new song in your voice.
That is the gap Taylor Swift's lawyers are now trying to plug.
Swift filed new forms with the US Patent and Trademark Office last week. The forms cover two voice clips and one stage image.
Josh Gerben, a US trademark lawyer who founded Gerben IP, broke the news in a blog post. The filings are listed under her firm, TAS Rights Management.
The new piece is the use of "sound marks." A sound mark is a rare type of trademark.
It has never been tested in court for a star's spoken voice, Gerben said.
The two voice clips are short ad reads from her album "The Life of a Showgirl." One is for Amazon Music Unlimited, and the other is a Spotify pre-save.
The image is a now-famous Eras Tour shot of Swift on stage. She is holding a pink guitar and wearing a sparkly outfit.
If the marks are granted, Swift could go after AI-made audio that mimics her voice. She could also block AI-made images that copy that look, even if they were not pulled from any real song or photo.
Old-school copyright stops people from copying an old song or photo. AI flips that.
It can make brand new audio that sounds like a star without ever touching the real master.
Gerben said AI lets users make brand new content that sounds like a star's voice. He added that this creates "a gap that trademarks may help fill."
Swift is not the only one testing this idea. Actor Matthew McConaughey filed the same kind of voice and image marks in recent months.
Both are running a legal test for the rest of the show business field.
For investors in music labels, streaming firms and AI firms, the signal here is much bigger than one star.
Swift has filed more than 300 trademark forms in the US alone. That comes from Leticia Caminero, a lawyer at WIPO, the world body for IP rights.
Each filing helps build her brand. It also trains lawyers in how to defend voice and image rights.
The push lands at a key moment. AI tools can now make music in a star's style, flood streaming sites with fake songs, and shape ads with cloned voices.
None of that copies an old recording, so old copyright rules do not always work.
Sound marks may be the first real fix. They are also a long shot in court.
The first big fight will set the tone for the rest.
If a court ever upholds a sound-mark claim against an AI voice clone, the rules of the road change overnight. The biggest names in music will move first, and everyone else will follow.
The case is new. The law is not.
The rules will need to bend if the new tech keeps moving as fast as it has.
