I am 77. My (and my husband’s) portfolio (all stocks) value has decreased about $700,000 since January. My RMD for my 403B for this year is about $22000. I hate to sell when prices are so low but I wonder if I can take the RMD money and buy stock shares for my Brokerage account (after tax money)? Also, am I eligible to put some of it into my Roth IRA? Thanks!
