Take, for example, Tesla's CEO Elon Musk.

He could earn as much as a trillion dollars if he hits certain targets.

And the CEO of Google's owner Alphabet could get almost $700 million in the next three years.

There's a new craze on Wall Street.

Hedge funds are growing their assets fast by slashing wealthy investors' tax bills.

It's called tax loss harvesting, and it's brought in $90 billion in assets since the start of last year.

But the practice has its fair share of controversy.

Here to explain all this is the FT's U.S.

investment correspondent, Amelia Pollard.

Hi, Amelia.

Hi, Sonia.

Thanks for having me.

Thanks for being on the show.

So explain tax loss harvesting to me.

What exactly are these hedge funds doing?

OK, so on top of this being a somewhat complex strategy, it has been very lucrative.

Why is this taking off now in particular?

Is there something that's going on in the wider market that's making this more attractive, or it's just kind of a new strategy and people are catching on to it?

What about risks just as a wealth management investment strategy?
