We do the same... Q1, one of Mom's accounts took a nose dive, fortunately, it matures (an IRA) the end of the year, thank gawd!
Yeah, don't get too worried. Think long term, even at her age. My mom's investments took a beating earlier this year, but they came back most of the way.
My ex-wife used to go into a panic every time the market took a hit. I had to calm her down. She wanted to sell off everything, which would have been a really stupid move. But, the market would recover, and she'd be glad we did it my way -- until the next dive, when she'd want to sell everything, again.
