My wife has a Fidelity account that she doesn’t look at. Father in law used to manage it for her and it’s been sitting stagnant since he stopped. She’s invested in a couple triple leveraged stocks and is up over 100% in both. I’m not familiar with them but everything I’m reading says they’re geared more for day trading. We don’t need the money, so my question is, should I just let it keep going or sell and invest in a more stable ETF?
