I'm sure several forum members remember October 19, 1987, aka Black Monday.
I was 22 years old and had just invested my life's savings into two different mutual funds on Thursday, October 15th. $10,000 hard earned dollars were worth about $6,000 the next week. I didn't sell and actually kept buying as I could and stuck to it. It hurt, but calm heads won. The only saving grace for me was that the MN Twins won the World Series, something I thought I'd never get to see.
Just a friendly pointer to young investors on the forum, there are going to be corrections in your investment lifetime, take them in stride and stay the course. It really does work.
The BEST lesson I have ever gotten on investing. I was 3 years into my first j*b and had started contributing to this new thing called a 401k in 1985. As I only had a small balance the damage was not too bad. But hearing all the news of doom and gloom forever then seeing full recovery in a couple of years hardened my resolve to ignore the naysayers and stay on track with my program. Served me well in 2000 and 2008.
