I didn't keep track of peak-to-trough, and only keep final-day financial data for each month on my spreadsheet, but as of Friday's close, I'm down about 1.3% from my 8/29/14 peak, which incidentally, was a new high.
On 9/30/14, I was down about 2.7%. I think there was a point somewhere in early October where I was down about 7-8% off that peak, but that data's gone now.
The last time I really had a correction worth whining about was from March-May 2012. That took me down about 6.7%. And I didn't fully recover until August.
I had a ~14% correction from July to August, back in 2011. That one seemed pretty scary, as I saw about $90K evaporate in just one month. That was the most money I had ever "lost" in a single month, and a good lesson to focus more on percentages, rather than dollar amounts!
I lost more money, percentage wise and $ amount, in the "Great Recession", but, that was dragged out over a longer time span. And for comparison, back during the tech bubble burst, 9/11 tragedy, and following recession, I didn't even have $90K to lose!
