Yes, trying to stay optimistic as well. We've been invested for over 25 years -- every time we've sold, the market has perked back up. So I've learned to stay put. This feels different. The market isn't just losing hundreds of pts. but thousands and not just for a day or two but for a week.
I have been at this , on an obsession level basis for 40 years. I track, research, and parse, compare these things to death.
Maybe the best advise I ever got was "Jump in when everyone else is on a stampede to the exits". This served me fantastically in '87, '01, and '09.
No one is sure of the bottom. Since I am retired, my exuberance is a little subuded, in deference toward more fixed income vehicles. I will go on record though, that the rally after the '09 crash is probably, (repeat probably with disclaimer) that the worst floor we will see on this crash (additonal 50%.). In any case, I am already bargain hunting. Addtions to my energy sector portfolio is peakiing my interest. Some big names there, are already under their '09 crash levels, and yielding 3-6% divys.
And again, folks.... like others have said.... Don't invest with money you need to live on.
