It’s so funny that you say that, cuz that’s exactly what I did! On the good side, I got extremely lucky and bought across the board literally the same week that the DOW hit the bottom in 2009. I made $150k profit (which is actually not that good compared to where the market is now.)
I bought some BAC at 2 and change for myself, my wife and my brother. Sold mine and my wife’s at around eight. Let my brother’s shares ride!
