Im 61 and have found no better investing tactic than to never day trade. I have tons of day trade experience, enough to know the best tactic is investing dollar cost averaging buys each month or week forever into VGT, VUG, VOO, VB. Buy $1,000 per month or $250 each every month for 30-40 years. Buy twice as much when markets collapse and never ever ever market time. Also buy ET and never ever ever sell. Re invest the dividends. Buy XOM and re invest the dividends. Pay off all debt. Always have a cash reserve from $10,000-$100,000 or more for emergencies. Never retire from generating cash reserves.
