First investment was Dec. 2014. Gotten my ass kicked and made some good trades for huge gains so far. The market for me is a constantly perplexing, ever changing, brutal bitch! I am humbled by the wisdom of others.
Find undervalued stocks and accumulate. Diversify. Don't gamble on junk. Buy on trend--there are always dips, esp on Fridays and options weeks. Watch ends of quarters. Be patient, use settled cash so you can bail fast. Have a plan and stick with it.
