You... are down, stocks are cheaper... so you REDUCE YOUR CONTRIBUTION AMOUNT????
HOW DO YOU WORK FOR A BANK?
Right now IS THE TIME TO MAX OUT YOUR CONTRIBUTIONS. MAX IT. Unless you are close to retirement, you should be just going ham on contributions. Look at it this way. There are two worst case scenario options.
A. The stock market collapses to zero. America is done. You better hope you have a bunker to hide in.
B. The stock market is not done, and it goes up SIMPLY DUE TO INFLATION over the next 20 years. This is ignoring growth. Just inflation will break you even (actually will double your money in 20 years).
But hey, you do you. I'm doing max. I only wish they would let us choose a dollar amount rather than a percentage so I can just set the maximum.
